B/S 页面点击后有个下载文档的操作，如何在下载后重新绑定页面信息
客户端点击后，后天有个下载页面的操作，这是下载的源代码private void Download(string filepath, string filename)
{
if (!String.IsNullOrEmpty(filename))
{
System.IO.Stream iStream = null;
byte[] buffer = new Byte[10240];
int length;
long dataToRead;
try
{
iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open,
System.IO.FileAccess.Read, System.IO.FileShare.Read);
Response.Clear();
dataToRead = iStream.Length;
long p = 0;
if (Request.Headers["Range"] != null)
{
Response.StatusCode = 206;
p = long.Parse(Request.Headers["Range"].Replace("bytes=", "").Replace("-", ""));
}
if (p != 0)
{
Response.AddHeader("Content-Range", "bytes " + p.ToString() + "-" + ((long)(dataToRead - 1)).ToString() + "/" + dataToRead.ToString());
}
Response.AddHeader("Content-Length", ((long)(dataToRead - p)).ToString());
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode(System.IO.Path.GetFileName(filename), System.Text.Encoding.UTF8));
iStream.Position = p;
dataToRead = dataToRead - p;
while (dataToRead > 0)
{
if (Response.IsClientConnected)
{
length = iStream.Read(buffer, 0, 10240);
Response.OutputStream.Write(buffer, 0, length);
Response.Flush();
buffer = new Byte[10240];
dataToRead = dataToRead - length;
}
else
{
dataToRead = -1;
}
}
}
catch (Exception ex)
{
Response.Write("Error : " + ex.Message);
}
finally
{
if (iStream != null)
{
iStream.Close();
}
}
}
}
这里filepath为文件所在路径，filename为文件名称；
这段代码执行后有关页面的操作都没有效果，例如：绑定页面信息、刷新页面等都无效，请问这该如何处理？？？ C# B/S 下载 页面刷新
补充：.NET技术 , C#
