Word Interop C#:使用现有页面插入新页面 [英] Word Interop C#: Insert new page using existing page

问题描述

我有一个Word模板文件，其中包含一个表，它有11行3列.因此，首页上的表格中有33个单元格.我在这些单元格中填充了一些数据，但是，如果记录数大于33(例如66)，则我将创建两个文件，每个文件包含33条记录.我想创建一个包含所有66条记录的文件，并且一个文件中应该有两个页面，而不是两个单独的文件.我该怎么办?

I have a word template file which contains a table and it has 11 rows and 3 columns. So there are 33 cells in table on first page. I fill these cell with some data, however if number of records are greater than 33 say 66, I am creating two files, each containing 33 records. I want to create single file which will contain all 66 records and there should be two pages in one file instead of two separate files. How should I do it?

以下是我用来创建一个doc文件的代码.

Following is the code I am using to create one doc file.

private static string FillTemplate(List<ClientListItem> clients, string fileName)
    {
        //Filled document file name
        var savedFileName = string.Empty;
        //Search template file in current directory
        var templateFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "templateFile.doc";

        #region Generate file for labels

        object missing = System.Type.Missing;
        // Create Word application
        WORD._Application app = new WORD.Application();

        try
        {
            Print("Creating label document.");
            // Create new file
            WORD._Document doc = app.Documents.Open(templateFilePath);

            //Print("Creating app selection object");
            WORD.Selection selection = app.Selection;

            //If the template file contains tables
            if (selection.Tables.Count > 0)
            {
                //Use first table
                //Table's are accessed with starting index as 1 not 0
                var tableToUse = selection.Tables[1];

                //Counter for number of parent caregivers inserted
                var counter = 0;
                //Number of parent caregivers
                var numberOfParentCaregivers = clients.Count;
                //Loop on each row
                //Rows are accessed with starting index as 1 not 0
                for (int rowIndex = 1; rowIndex <= tableToUse.Rows.Count; rowIndex++)
                {
                    //Loop on each column
                    //Columns are accessed with starting index as 1 not 0
                    for (int columnIndex = 1; columnIndex <= tableToUse.Columns.Count; columnIndex++)
                    {
                        //If counter has reached to its limit
                        if (counter + 1 > numberOfParentCaregivers)
                        {
                            //Stop
                            break;
                        }

                        //If current column index is even
                        if (columnIndex % 2 == 0)
                        {
                            //Do not process it
                            //Why? Check template file for yourself
                            continue;
                        }

                        //Get parent caregiver to set
                        var parentCaregiver = clients[counter];

                        Print("Generating label to add to document.");

                        //Get label to add to document
                        var labelToAdd = string.Format("{0} {1},{6}{2},{6} {3}, {4} {5}", parentCaregiver.Parent1LastName, parentCaregiver.Parent1FirstName,
                            parentCaregiver.Parent1StreetAddress, parentCaregiver.Parent1City, parentCaregiver.Parent1State, parentCaregiver.Parent1Zip, Environment.NewLine);

                        //Print(string.Format("Adding label {0} at {1}, {2} position.", labelToAdd, rowIndex, columnIndex));

                        //Get cell to set value
                        var tableCell = tableToUse.Cell(rowIndex, columnIndex);
                        //Set text in cell
                        tableCell.Range.Text = labelToAdd;
                        //Middle align text
                        tableCell.Range.ParagraphFormat.Alignment = WORD.WdParagraphAlignment.wdAlignParagraphCenter;

                        Print(string.Format("Label added {0} at {1}, {2} position.", labelToAdd, rowIndex, columnIndex));
                        counter++;
                    }

                    //If counter has reched to its limit
                    //i.e. no parent caregivers to process - all processed
                    if (counter + 1 > numberOfParentCaregivers)
                    {
                        //stop
                        break;
                    }
                }
            }

            // Set file name to save
            savedFileName = string.Format(@"{0}{1}{2}", Path.GetTempPath(), fileName, Path.GetExtension(templateFilePath));
            object fname = savedFileName;
            Print(string.Format("Saving new document at {0}", savedFileName));
            // SaveAs new file
            doc.SaveAs(ref fname, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
            Print(string.Format("{0} saved successfully.", savedFileName));
            app.Documents.Close(ref missing, ref missing, ref missing);
        }
        catch (Exception exc)
        {
            Print("Exception while generating label document");
            Print(exc.ToString());
            //Set file Name to empty string
            savedFileName = string.Empty;
        }
        finally
        {
            // Close Word application
            app.Quit(ref missing, ref missing, ref missing);
            Marshal.ReleaseComObject(app);
            app = null;
            GC.Collect();
            GC.WaitForPendingFinalizers();
            GC.Collect();
            GC.WaitForPendingFinalizers();
        }

        //Return saved file name
        return savedFileName;

    }

请提出更改建议，以便我可以根据要添加到模板文件中的记录数创建任意数量的页面.

Please suggest changes so that I can create any number of pages based on number of records to add in template file.

谢谢， 尼基尔.

推荐答案

我更改了遍历要插入表中的所有项的代码，而不是遍历了表的单元格.在此循环内，将增加列和行的索引，并且当所有单元格都已填充时，在粘贴原始表副本的文档末尾插入一个分页符.此时，两个索引都重置为1，将新表设置为要使用的表，并且一切正常进行.

I changed your code looping over all the items to insert in the table(s) instead of looping over the cells of the table. Inside this loop the indexes of the columns and rows are incremented and when all the cells have been filled a page break is inserted at the end of the document where a copy of the original table is pasted. At this point the two indexes are reset to 1, the new table is set as the one to be used, and everything continues normally.

这是代码:

    private static string FillTemplate(List<ClientListItem> clients, string fileName)
    {
        //Filled document file name
        var savedFileName = string.Empty;
        //Search template file in current directory
        var templateFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "templateFile.doc";



        object missing = System.Type.Missing;
        // Create Word application
        WORD._Application app = new WORD.Application();

        try
        {
            app.Visible = true;
            Print("Creating label document.");
            // Create new file
            WORD._Document doc = app.Documents.Open(templateFilePath);

            //Print("Creating app selection object");
            WORD.Selection selection = app.Selection;

            //If the template file contains tables
            if (selection.Tables.Count > 0)
            {
                //Use first table
                var tableToUse = selection.Tables[1];

                //copy the empty table in the clipboard
                WORD.Range range = tableToUse.Range;
                range.Copy();

                int rowIndex = 1;
                int columnIndex = 1;

                // loop over all the items to insert
                foreach (ClientListItem parentCaregiver in clients)
                {
                    // check if all the cells in the current row have been used
                    if (columnIndex > tableToUse.Columns.Count)
                    {
                        // if this is the case increment the row index and restart from the first column
                        columnIndex = 1;
                        rowIndex++;
                        // check if all the rows in the current table have been used
                        if (rowIndex > tableToUse.Columns.Count)
                        {
                            // if this is the case create a new table and restart from the first row
                            rowIndex = 1;
                            // first go to end of document
                            selection.EndKey(WORD.WdUnits.wdStory, WORD.WdMovementType.wdMove);
                            // then add page break
                            object breakType = WORD.WdBreakType.wdPageBreak; 
                            selection.InsertBreak(ref breakType);
                            // add a new table (initially with 1 row and one column) at the end of the document
                            // i.e. on the new page
                            WORD.Table tableCopy = doc.Tables.Add(selection.Range, 1, 1, ref missing, ref missing);
                            // paste the original empty table over the new one
                            tableCopy.Range.Paste();
                            // makes the copied table the one to use
                            tableToUse = tableCopy;
                        }
                    }
                    Print("Generating label to add to document.");

                    //Get label to add to document

                }


            }
