無法通過c＃下載exe文件.net

我設計了一個網站，通過它我點擊一個按鈕時.EXE文件應該從我的電腦的特定路徑下載。無法通過c＃下載exe文件.net

但它並沒有下載exe文件，而是下載了網站的aspx頁面。

我使用下面的代碼：

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

該頁面的內容是什麼？確保它不是403錯誤或什麼 – Sarrus

@Sarrus沒有403錯誤。頁面的內容是文本框和按鈕。\ –

能否請您試試這個。

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.(e.g. 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."); 
    } 
}

我希望我編輯的評論能幫助理解。但請注意：這只是一個粗略的總結。你可以做的比這更多。

其工作正常..謝謝你Usman ..但實際上我無法理解你的代碼，你可以解釋一下。 –

你想了解什麼？我的意思是哪條線？ –

Response.AddHeader（「Content-Disposition」，「attachment; filename =」+ file.Name）; Response.AddHeader（「Content-Length」，file.Length.ToString（））; Response.ContentType =「application/octet-stream」; Response.WriteFile（file.FullName）; –
