无法通过c＃.net下载exe文件

我设计了一个网站，当我点击一个按钮时，.EXE文件应该从我的计算机的特定路径下载。

但它不下载exe文件而不是下载网站的aspx页面。

我使用以下代码：

WebClient myWebClient = new WebClient(); // Concatenate the domain with the Web resource filename. myWebClient.DownloadFile("http://localhost:1181/Compile/compilers/sample2.exe", "sample2.exe");

你能试试吗？

 string filename = "yourfilename"; if (filename != "") { string path = Server.MapPath(filename); System.IO.FileInfo file = new System.IO.FileInfo(path); if (file.Exists) { Response.Clear(); //Content-Disposition will tell the browser how to treat the file.(eg in case of jpg file, Either to display the file in browser or download it) //Here the attachement is important. which is telling the browser to output as an attachment and the name that is to be displayed on the download dialog Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); //Telling length of the content.. Response.AddHeader("Content-Length", file.Length.ToString()); //Type of the file, whether it is exe, pdf, jpeg etc etc Response.ContentType = "application/octet-stream"; //Writing the content of the file in response to send back to client.. Response.WriteFile(file.FullName); Response.End(); } else { Response.Write("This file does not exist."); } } 

我希望我编辑的评论有助于理解。 但请注意：这只是一个粗略的总结。 你可以做更多的事情。
