求助 文件下载问题 在线等..........
string LocalPath= "H:/ERPtest_FTP/ "+TheFtpType+ "/ "+Theremotepath+ "/ ";
stringTheName=LocalPath+LocalFileName;
string TN=LocalFileName;
string TT= "Content-Disposition ";
string TV= "attachment;filename= "+HttpContext.Current.Server.UrlEncode(Request.QueryString[ "strFilename "].ToString());
Response.AddHeader(TT,TV);
Response.WriteFile(TheName);
用此段代码下载
当文件为PDF时文件总会比正确的文件大2K左右，因此下载后打开会报错。但JPG、Xls等却是正确的。
如何解决？？

用這種方式：
private void FileDownload()
{
String FullFileName = Server.MapPath( "文件路径 ");
FileInfo DownloadFile = new FileInfo(FullFileName);
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.ContentType = "application/octet-stream ";
Response.AppendHeader( "Content-Disposition ", "attachment;filename= " + HttpUtility.UrlEncode(DownloadFile.FullName, System.Text.Encoding.UTF8));
Response.AppendHeader( "Content-Length ", DownloadFile.Length.ToString());
Response.WriteFile(DownloadFile.FullName);
Response.Flush();
Response.End();
}
