下载代码运行奇慢，为什么啊？
private void Button1_Click(object sender, System.EventArgs e)
{
System.IO.FileStream r = new System.IO.FileStream( "e:/后缀.txt ", System.IO.FileMode.Open);
Response.Buffer = false;
Response.AddHeader( "Connection ", "Keep-Alive ");
Response.ContentType = "application/octet-stream ";
Response.AddHeader( "Content-Disposition ", "attachment;filename= " + System.IO.Path.GetFileName( "e:/后缀.txt "));
Response.AddHeader( "Content-Length ", r.Length.ToString());
while ((true))
{
byte[] Buffer = new byte[1024];
Int64 leng;
leng = r.Read(Buffer, 0, 1024);
if (leng == 0)
{
goto exitWhileStatement0;
}
if ((leng == 1024))
{
Response.BinaryWrite(Buffer);
}
else
{
byte[] b = new byte[leng];
Int64 i;
for (i = 0; i <= leng; i++)
{
b[i] = Buffer[i];
}
Response.BinaryWrite(b);
}
}
exitWhileStatement0: ;
r.Close();
File.Delete( "e:/后缀.txt ");
}
[解决办法]
你是在本机调试的吗/
注意缓冲数组的分配问题
