C# 如何将包含图像的网格中的数据导出到excel中？

我想将数据从包含图像的网格导出到excel

我使用以下代码-

 private void CreateXL()
 {
    Response.Clear();
    Response.AddHeader("content-disposition", "attachment;filename=xxxxxxxt.xls");
    Response.Charset = "";

    Response.ContentType = "application/vnd.xls";
    StringWriter objStringWriter = new StringWriter();
    HtmlTextWriter objHtmlTextWriter = new HtmlTextWriter(objStringWriter);

    Gridview.RenderControl(objHtmlTextWriter);
    Response.Write(objStringWriter.ToString());
    Response.End();
 }

但是在excel中，我看不到图像，而不是图像，我收到一条信息，上面说：“链接的图像无法显示，文件可能已被移动、重命名或删除。”。验证链接是否指向正确的文件和位置。”

如何解决此问题？

全文：

private void Excel\u Export（）
{
Response.Clear（）；
Response.Buffer=true；
AddHeader（“内容处置”、“附件；文件名=GridViewExport.xls”）；
响应。Charset=“”；
Response.ContentType=“application/vnd.ms excel”；
StringWriter sw=新的StringWriter（）；
HtmlTextWriter hw=新的HtmlTextWriter（sw）；
GridView1.AllowPaging=false；
GridView1.DataBind（）；
对于（int i=0；i

此URL肯定会对您有很大帮助。。。。这对你有用吗？？？？？？？？

private void Excel_Export()
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition","attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.DataBind();

for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = GridView1.Rows[i];
//Apply text style to each Row
row.Attributes.Add("class", "textmode");
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
