我在ASP.NET C#Page中有一个Gridview。它有几列和一个图像列。我可以将整列导出到Excel文件,但image列为空。顺便说一下,我使用完整的路径。
任何想法?

是default.aspx中的是(对于本地导出)
ImageUrl="http://localhost:4056/CSharp/banner.gif"
instead of ImageUrl="~/banner.gif"
或(用于远程导出)
http://your ip address here :port/foldername/filename

Response.Clear(); //这将清除任何标头或先前输出的响应 Response.Buffer = true; //确保同时呈现整个输出
Response.ContentType = "application/vnd.ms-excel";
StringWriter stringWriter = new StringWriter(); //System.IO namespace should be used
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
GridView2.GridLines = GridLines.Both;
GridView2.RenderControl(htmlTextWriter);
Response.Write(stringWriter.ToString());
Response.End();
