在c#中使用ExcelLibrary输出到Excel

Question

下面的代码使用controller.file输出到csv文件。我想将其更改为输入到excel工作表(.xls)而不是csv文件。我在这里使用这个库来做这件事..http://code.google.com/p/excellibrary/

根据这篇stackoverflow帖子..Create Excel (.XLS and .XLSX) file from C#

编辑：

foreach (var value in valueDataList)

    {
        var value1 = xxxxxxx    // this value is set here based on a query.. 
        int value2 = xxxxxxxx   // this value is set here based on a query.. 

        byte[] content;

        using (var ms = new MemoryStream())  
           {
              using (var writer = new StreamWriter(ms))
                {
                  writer.WriteLine("ValueHeading1   " + " ValueHeading2");
                  writer.WriteLine(value1 + "              " + value2);                         
                }
                  content = ms.ToArray();
                  return File(content, "text/csv", "demo.csv");
            //ExcelLibrary.DataSetHelper.CreateWorkbook("MyExcelTest.xls", content);

           }
    }   

如何使用此库修改现有代码以将其放入excel。代码中的最后一个注释行不起作用，因为它要求“content”是一个数据集，而不是一个字节。谢谢你的帮助。

public ActionResult Excel()
{
    DataSet ds = ...
    using (var ms = new MemoryStream())  
    {
        ExcelLibrary.DataSetHelper.CreateWorkbook(ms, ds)
        return File(ms.ToArray(), "application/vnd.ms-excel", "demo.xls");
    }
}
