这是一个提供下载文件的函数.但到客户端后显示的文件名称是乱码.请进来看看,帮忙解决一下.

Question

public bool LoadDownFile(string FileName,string ClientFileName,System.Web.UI.Page page)
{
try
{
string type = FileName.Split('.')[1];
FileInfo fileinfo = new FileInfo(FileName);
FileStream stream = File.OpenRead(FileName);
byte[] fb = new byte[fileinfo.Length];
stream.Read(fb,0,fb.Length);
System.Web.HttpResponse rps = page.Response;
rps.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
rps.Charset = "utf-8";
rps.BufferOutput=false;
rps.ContentType="application/" + type;
ClientFileName = System.Web.HttpUtility.UrlEncode(FileName).Replace("+","%20");
rps.AppendHeader("Content-Disposition", "attachment;FileName=" + ClientFileName);
rps.ContentType = "application/octet-stream"; 
rps.BinaryWrite(fb);                    
stream.Close();
}
catch(Exception)
{
return false;
}
return true;
}

给你个下栽函数:
private void LoadFile(string FilePath,string FileName)
{
try
{
string strFile=FilePath;
if(!System.IO.File.Exists(strFile))
{
return;
}
Response.Clear();
Response.ClearHeaders();
Response.Charset = "utf-8";
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/octet-stream"; 
FileInfo fi=new FileInfo(strFile);
Response.AddHeader("Content-Disposition","attachment;  filename="  +  HttpUtility.UrlEncode(FileName)) ;
Response.AddHeader("Content-Length",fi.Length.ToString());
byte[] tmpbyte=new byte[1024*8];
FileStream fs=fi.OpenRead();
int count;
while((count=fs.Read(tmpbyte,0,tmpbyte.Length))>0)
{
Response.BinaryWrite(tmpbyte);
Response.Flush();
}
fs.Close();
Response.End();
}
catch(Exception err)
{
throw new Exception("文件下载失败"+err.Message);
}
}
