C# 如果文件名放置到目录不起作用

C# 如果文件名放置到目录不起作用,c#,filenames,if-statement,C#,Filenames,If Statement,我有一个小问题…我正在编写自动更新程序,当我下载.exe文件时,我想把它放到main dir..和others.extension到sub dir File.exe=这里是我下载到主目录的地方 Else=放置到子目录…但它不工作,请将所有内容放置到主目录 if(ex[1] == "File.exe") { if (File.Exists(path)) { if(File.Exists(String.Format("{0}WoW.exe", wow.GetValue

使用
Path.combined
进行路径操作,以确保文件名的正确性。除此之外,我不知道你的代码有什么问题。您是否追踪了它以找出导致您的问题的原因。

请详细说明“不起作用”?这并没有告诉我们问题出在哪里。
