protected void DownLoadButton_Click(object sender, EventArgs e)
{
string fileName = _sourcename;//客户端保存的文件名
string str = _videoUrl;
string[] strFen = str.Split('/');
string filePath = Server.MapPath("VideoSource/" + strFen[1]);//路径
FileInfo fileInfo = new FileInfo(filePath);
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
Response.AddHeader("Content-Length", fileInfo.Length.ToString());
Response.AddHeader("Content-Transfer-Encoding", "binary");
Response.ContentType = "application/octet-stream";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
Response.WriteFile("VideoSource\\" + strFen[1]);
Response.Flush();
Response.End();
}
我打断点监视了一下filePath变量，路径是"D:\\CLSoftWare\\NewNetText\\VideoSource\\CSharpDenglu1.wmv"
跳出这个循环以后它会显示如下错误：
Microsoft JScript 运行时错误: Sys.WebForms.PageRequestManagerTimeoutException: 服务器请求超时。
这是怎么回事呀？请高人指点
