How to create and download excel document using asp.net ?

的目的是使用XML，LINQ或任何通过浏览器的Excel文档发送给客户。

The purpose is to use xml, linq or whatever to send an excel document to a customer via a browser.

编辑：使用情况

用户负荷在浏览器中的GridView（与Ajax框架制造），在GridView直接连接到SQL数据库。

推荐答案

首先，我已经下载的<一个href=\"http://www.microsoft.com/downloads/details.aspx?FamilyID=c6e744e5-36e9-45f5-8d8c-331df206e0d0&DisplayLang=en\"相对=nofollow> Open XML格式SDK 2.0 。

Starter kit

First i have downloaded the Open XML Format SDK 2.0.

它配备了3有用的工具：

It comes with 3 useful tools in :

C：\\ Program Files文件\\ Open XML格式SDK \\ V2.0 \\工具

C:\Program Files\Open XML Format SDK\V2.0\tools

• DocumentReflector.exe 至极汽车
  生成C＃打造
  US preadsheet从code。


• OpenXmlClassesExplorer.exe 显示
  ECMA规范和类
  文档（使用MSDN风格
  格式）。


• OpenXmlDiff.exe 图形比较
  可用两个开放式XML文件和搜索
  错误。

• DocumentReflector.exe wich auto generate the c# to build a spreadsheet from the code.
• OpenXmlClassesExplorer.exe display Ecma specification and the class documentation (using an MSDN style format).
• OpenXmlDiff.exe graphically compare two Open XML files and search for errors.

我建议任何人谁开始的改名 * 的.xlsx *的到的* *。拉链，所以你可以看到谁推动了S preadsheet（对于例如我们的表是在XL \\工作表）的XML文件。

I suggest anyone who begin to rename *.xlsx *to* *.zip, so you can see the XML files who drive our spreadsheet ( for the example our sheets are in "xl\worksheets" ).

免责声明：我偷了所有的code从的 MSDN技术文章 ; d

Disclaimer : I have stolen all the code from an MSDN technical article ;D

以下code使用*的.xlsx模板我手动进行，以便能够对其进行修改。

The following code use an *.xlsx template i made manually to be able to modify it.

命名空间的引用

using System.IO;
using System.Xml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;
using DocumentFormat.OpenXml;


// Database object
        DataClassesDataContext db = new DataClassesDataContext();

        // Make a copy of the template file.
        File.Copy(@"C:\inetpub\wwwroot\project.Web\Clients\Handlers\oxml-tpl\livreurs.xlsx", @"C:\inetpub\wwwroot\project.Web\Clients\Handlers\oxml-tpl\generated.xlsx", true);

        // Open the copied template workbook. 
        using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(@"C:\inetpub\wwwroot\project.Web\Clients\Handlers\oxml-tpl\generated.xlsx", true))
        {
            // Access the main Workbook part, which contains all references.
            WorkbookPart workbookPart = myWorkbook.WorkbookPart;

            // Get the first worksheet. 
            WorksheetPart worksheetPart = workbookPart.WorksheetParts.ElementAt(2);

            // The SheetData object will contain all the data.
            SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();

            // Begining Row pointer                       
            int index = 2;

            // Database results
            var query = from t in db.Clients select t;

            // For each item in the database, add a Row to SheetData.
            foreach (var item in query)
            {
                // Cell related variable
                string Nom = item.Nom;

                // New Row
                Row row = new Row();
                row.RowIndex = (UInt32)index;

                // New Cell
                Cell cell = new Cell();
                cell.DataType = CellValues.InlineString;
                // Column A1, 2, 3 ... and so on
                cell.CellReference = "A"+index;

                // Create Text object
                Text t = new Text();
                t.Text = Nom;

                // Append Text to InlineString object
                InlineString inlineString = new InlineString();
                inlineString.AppendChild(t);

                // Append InlineString to Cell
                cell.AppendChild(inlineString);

                // Append Cell to Row
                row.AppendChild(cell);

                // Append Row to SheetData
                sheetData.AppendChild(row);

                // increase row pointer
                index++;                

            }

            // save
            worksheetPart.Worksheet.Save();

        }

我还没有说完呢，我的第二份工作是自动下载在S preadsheet修改后

I havent finished yet, my second job is to auto download the spreadsheet after modification.

最后，我将用户重定向到我的生成S- predsheet（从我的aspx）

Finally, i redirect the user to my generated spredsheet (from my aspx)

 context.Response.Redirect("Oxml-tpl/generated.xlsx");
