有个朋友问我下载弹出提示框的写法，具体如下：
出现提示框
string strFile="F:\\a.doc";//路径根据实际情况而定
if(!System.IO.File.Exists(strFile))
{
Response.Write("<script language='javascript'>alert('对不起，文件不存在！');</script>");
return;
}
Response.Clear();
Response.ClearHeaders();
Response.Charset = "GB2312";
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/octet-stream";
FileInfo fi=new FileInfo(strFile);
Response.AddHeader("Content-Disposition","attachment; filename=" + HttpUtility.UrlEncode(fi.Name)) ;
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();
直接在浏览器中打开
string strFile="F:\\a.doc";//路径根据实际情况而定
Response.Clear();
Response.ClearHeaders();
Response.Charset = "GB2312";
Response.ContentEncoding =System.Text.Encoding.UTF8;
Response.ContentType = "application/msword";
Response.WriteFile(strFile);
