如何在c#中的服务器上检查文件是否存在 [英] how to check if a file exists on a server in c#

问题描述

大家好，

请帮帮我.我想知道如何检查C#中服务器上是否存在文件.

Hi everyone,

please help me out. I want to know how to check whether a file exists on a server or not in C#.

推荐答案

文件类具有静态方法Exists.那应该有帮助.由于您提到的是服务器，因此我假设您想将该信息发送回UI或客户端.

您必须前往服务器才能了解这一点.

File class has a static method Exists. That should help. Since you are mentioning server, I assume you want to sent that information back to UI or the client.

You will have to make a trip to server to get to know this.

看看这种方法

您可以在服务器上尝试Web Service允许托管.

使用[WebMethod] File.Exist("FileNameOnServerLocation")并返回结果.

添加网络参考，您可以从网站或EXE使用它.

You can try Web Service on the server if you allowed to host.

Use a [WebMethod] File.Exist("FileNameOnServerLocation") and return the result.

Add a web reference, you can consume it from website or EXE.
