推荐答案

是否尝试过在Google中搜索?关于文件删除，有很多代码片段.只需尝试熟悉一下 System.IO [

Tried searching in Google? There are many code snippets out there about file deletion. Just try to familiarize yourself about System.IO[^] namespace. As for the confirmation, you can do a Javascript code to display a confirmation box to the user before proceeding with the deletion.

要显示Yes/No对话框，您可以使用Ajax控件，然后从您可以使用System.IO.File.Delete("File path and name");校准服务器端代码以删除文件；

您可以将此代码放在try catch块中，如果文件已在内存中打开，则捕获异常

to display Yes/No dialog box you can use Ajax control and from that you can cal server side code to delete file with System.IO.File.Delete("File path and name");

you can place this code in try catch block and catch the exception if file is already open in memory
