如何删除路径的DirectorySeparatorChar？ [英] How do I remove the DirectorySeparatorChar of an Path?

问题描述

大家好。



我目前有一点问题，因为系统无法识别以反斜杠结尾的路径



我在这里尝试这个，但它对论证没有影响

Hi guys.

I have currently a little Problem, because the System doesn't recognizes a Path that ends with a backslash

I'm trying this here, but it has no affect on the argument

args[0] = args[0].TrimEnd(Path.DirectorySeparatorChar);

谢谢。



真诚地：

Jonas

thanks.

Sincerely:
Jonas

推荐答案

系统无法识别以反斜杠结尾的路径

是的，确实如此：它说这是一个文件夹。

"the System doesn't recognizes a Path that ends with a backslash"
Yes, it does: It says "this is a folder".

static void Main(string[] args)
    {
    string[] files = Directory.GetFiles(args[0]);
    foreach (string s in files) Console.WriteLine(s);
    args[0] = args[0].TrimEnd(Path.DirectorySeparatorChar);
    foreach (string s in args)
        Console.WriteLine(s);
    }

然后使用ConsoleTester D：\ temp \运行应用程序，它会打印临时文件列表文件夹。



但是......请注意，Path.DirectorySeparatorChar只是反斜杠 - 它也不会与斜杠'/'匹配，但是Windows很满意。



如果您的路径以分隔符结尾，则它是文件夹路径，而不是文件路径。所以File.RealAllLines（等等）不起作用 - 它们需要一个文件，而不是一个文件夹。

Then run the app with "ConsoleTester D:\temp\", and it prints the list of files in my temporary folder.

But...Do note that Path.DirectorySeparatorChar is only backslash - it will not match a slash '/' as well, but Windows is happy with either.

And if your path ends with a separator character, it's a folder path, not a file path. So File.RealAllLines (and so forth) will not work - they need a file, not a folder.
