以下是使用ASP .NET下载文件的示例代码.
Here is the sample code to download a file using ASP .NET
try
{
System.String filename = "myFile.txt";
// set the http content type to "APPLICATION/OCTET-STREAM
Response.ContentType = "APPLICATION/OCTET-STREAM";
// initialize the http content-disposition header to
// indicate a file attachment with the default filename
// "myFile.txt"
System.String disHeader = "Attachment; Filename=\"" + filename +
"\"";
Response.AppendHeader("Content-Disposition", disHeader);
// transfer the file byte-by-byte to the response object
System.IO.FileInfo fileToDownload = new
System.IO.FileInfo("C:\\download\\myFile.txt");
Response.Flush();
Response.WriteFile(fileToDownload.FullName);}
catch (System.Exception e)
// file IO errors
{
SupportClass.WriteStackTrace(e, Console.Error);
}
