c# - 如何在c#中将一些文本写入excel文件

Question

我正在将网格表添加到 excel 并在 excel 中添加标题。

     string subject = lbl_Subj.Text;
    Response.Clear();
    Response.Buffer = true;
    Response.ClearHeaders();
    Response.AddHeader("Cache-Control", "no-store, no-cache");        
    Response.AddHeader("content-disposition", "attachment;filename=" + subject + "-Status");
    Response.Charset = "";
    this.EnableViewState = false;    
    Response.ContentType = "application/vnd.ms-excel";
    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
    Grid_UserTable.RenderControl(htmlWrite);        
    rptList.RenderControl(htmlWrite);       
    Response.Write(stringWrite.ToString());     
    Response.End();

如何在 excel 中添加一些文本，我想添加一些字符串，例如

string add="this is the text I want to add to the excel";

Answer 1

尝试添加：htmlWrite.WriteLine(add);

  string subject = lbl_Subj.Text;
    Response.Clear();
    Response.Buffer = true;
    Response.ClearHeaders();
    Response.AddHeader("Cache-Control", "no-store, no-cache");        
    Response.AddHeader("content-disposition", "attachment;filename=" + subject + "-Status");
    Response.Charset = "";
    this.EnableViewState = false;    
    Response.ContentType = "application/vnd.ms-excel";
    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

    htmlWrite.WriteLine(add);

    Grid_UserTable.RenderControl(htmlWrite);        
    rptList.RenderControl(htmlWrite);       
    Response.Write(stringWrite.ToString());     
    Response.End();

只要您使用的是 Office 2007/2010，就可以使用 Office Open XML - http://msdn.microsoft.com/en-us/office/ee358824

Answer 3

您不能使用字符串/html 编写器，因为 excel 是二进制的。

您必须使用 Excel PIA 来创建 Excel 工作表。

hw.RenderBeginTag("strong");
hw.Write("this is the text I want to add to the excel" + DateTime.Now);
