如何刪除從服務器下載的文件

Question

我已經創建了一個mdb文件，並使用asp.net壓縮該文件，之後我正在下載zip文件。

下載文件後，我只想通過使用c＃刪除目錄中的文件？

我剛剛嘗試過，但下載是在按鈕單擊存在後完成的，但我想下載該文件，下載後將其從目錄中刪除。

Answer 1

這可能會幫助你

String filename=Directory.GetFile(@"c:\filename"); 
File.Delete(filename); 

Answer 2

您是否嘗試過這個代碼？

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(); 

     // Delete the file... 
     System.IO.File.Delete(file.FullName);  

    } 
    else 
    { 
     Response.Write("This file does not exist."); 
    } 
}

有一個例子：

protected virtual void DownloadNDelete(string sFilePath, string sContentType)  
{ 

string FileName = Path.GetFileName(sFilePath); 
Response.Clear(); 
Response.AddHeader("Content-Disposition","attachment; filename=" + FileName); 
Response.ContentType = sContentType; 
Response.WriteFile(sFilePath); 
Response.Flush(); 
this.DeleteFile(sFilePath); 
Response.End(); 

}
