无法复制Word文档的特定页面 [英] Not able to copy specific pages of word document

问题描述

我试图剪切我的word文档(.docx)的特定页面，比如说2、4.我正在使用for循环遍历根据根据,进行拆分的页面.下面是代码相同的

I am trying to cut specific pages of my word document(.docx), say 2, 4. I am using for loop to traverse as per the page gave splitting it based on ,.Below is the code for the same

if (startEnd.Contains(','))
{
    arrSpecificPage = startEnd.Split(',');

    for (int i = 0; i < arrSpecificPage.Length; i++)
    {
        range.Start = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).Start;
        range.End = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).End;
        range.Copy();
        newDocument.Range().Paste();                    
    }
    newDocument.SaveAs(outputSplitDocpath);
}

，但是此代码的问题在于它仅将最后一页仅复制到新文档，即在这种情况下为4.如何添加2?代码有什么问题?

but the issue with this code is that its just copying the last page only to the new document i.e 4 in this case. How to add 2 as well? What's wrong in the code?

推荐答案

由于您始终将整个文档范围"指定为目标，因此每次粘贴文档的全部内容都会被替换.

Since you always specify the entire document "range" as the target, each time you paste the entire content of the document is replaced.

使用Range对象而不是选择对象是正确的，但是如果您思考诸如选择对象之类的范围，则会有所帮助.如果选择所有内容(Ctrl + A)然后粘贴，则所选内容将替换为粘贴的内容.分配给范围的任何内容都将替换范围的内容.

It's correct that you work with a Range object and not with a selection, but it helps if you think about a Range like a selection. If you select everything (Ctrl+A) then paste, what was selected is replaced by what is pasted. Whatever is assigned to a Range will replace the content of the Range.

解决此问题的方法是折叠"范围-就像按右箭头或左箭头键将选择折叠"到其起点或终点一样.在对象模型中，这是Collapse方法，该方法带有一个参数，该参数指示是折叠到起点还是终点(请参见下面的代码).

The way to solve this is to "collapse" the Range - think of it like pressing the Right-arrow or left-arrow key to "collapse" a selection to its start or end point. In the object model, this is the Collapse method that takes a parameter indicating whether to collapse to the start or end point (see the code below).

请注意，我还更改了代码以使用document.Content而不是Document.Range. Content是一个属性，它返回文档的整个主体； Range是一种期望定义Range的起点和终点的方法.使用属性是整个文档的首选方法.

Note that I've also changed the code to use document.Content instead of Document.Range. Content is a property that returns the entire body of the document; Rangeis a method that expects a start and end point defining a Range. Using the property is the preferred method for the entire document.

if (startEnd.Contains(','))
{
    arrSpecificPage = startEnd.Split(',');

    for (int i = 0; i < arrSpecificPage.Length; i++)
    {
        range.Start = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).Start;
        range.End = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).End;
        range.Copy();
        Word.Range targetRange = newDocument.Content
        targetRange.Collapse(Word.WdCollapseDirection.wdCollapseEnd);
        targetRange.Paste();                    
    }
    newDocument.SaveAs(outputSplitDocpath);
}
