从c＃中的字符串文件路径中删除额外的反斜杠“\\”

Question

How to convert

"String path = @"C:\\Abc\\Omg\\Why\\Me\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\";

into

String path = @"C:\\Abc\\Omg\\Why\\Me\\" .

My approach is to first reverse the string and then remove all the "\\" till we get first char , and the reverse it again.

How to do this in C#, is there any method for such operation?

Answer 1

You can just construct path using the Path static class:

string path = Path.GetFullPath(@"C:\Abc\Omg\Why\Me\\\\\\\\\\\\\\\\\\\\\");

After this operation, variable path will contain the minimal version:

C:\Abc\Omg\Why\Me\

Answer 2

You can use path.TrimEnd('\\\\') . Have a look at the documentation for String.TrimEnd .

If you want the trailing slash, you can add it back easily.

Answer 3

var path = @"C:\Abc\Omg\Why\Me\\\\\\\\\\\\\\\\\\\\\";
path = path.TrimEnd('\\') + '\\';

another solution is

var path = @"C:\Abc\Omg\Why\Me\\\\\\\\\\\\\\\\\\\\\";
path = Path.GetFullPath(path);

Answer 4

You can also remove multiple slash using Regular expression as follow:

 string path= @"C:\Abc\Omg\Why\Me\\\\\\\\\\\\\\\\\\\\\";
 path = Regex.Replace(path, "\\\\{2,}", @"\");
