How can i make a path short in a string?

This is just a example the string can something else.

C#

string test = "xcopy c:\test\test\test\name.bat d:\test\test\test\hi.bat"

and i want to have

C#

string test = "xcopy c:\..\name.bat d:\..\hi.bat"

other example

string test = "whatever c:\test\test\test\name.bat whatever"
to
string test = "whatever c:\..\name.bat whatever"

other example

regedit.exe /e:a "D:\data\backup\laptop\CCleaner\CCleaner.reg" "HKEY_CURRENT_USER\Software\Piriform\CCleaner"

to
regedit.exe /e:a "D:\..\..\..\..\CCleaner.reg" "HKEY_CURRENT_USER\..\..\CCleaner"

at autoit i can do this with

Func _shortstringpath($data)
Return StringRegExpReplace($data, '("[^\\]+\\)(?:[^\\"]+\\)*([^"]+")', "$1...\\$2")
EndFunc

i want to do this in c# 2.0

this is the link with the question for autoit code but now i need it in c#

Why do you need a relative ("short"?) path?
How do you know what the reference (current?) directory is?
For relative paths, you need a reference: relative to what?
E.g. if you intend to write that xcopy command to a batch file that will later be executed somewhere, you need to set the current directory (cd ...) before that relative call.
And: as others noted: there is no way to combine relative with absolute paths. You might use wildcards instead, but this is very uncommon and error prone.

Solution 1

You can use relative paths - which is what the ".." bit in a path means: "the directory above the current", "." means "the current directory".
But you can't combine a relative path with any part of an absolute path specification.
So if you start your path with an absolute specification like "C:\" you can't then use a relative path specifier in the path and expect it to work!

Why not just use File.Move[^]?

Solution 4

try this method :

C#

public static string GetShortPath(string fullPath)
       {
            var ellipsesPath = "";

            if (string.IsNullOrEmpty(fullPath)) return ellipsesPath;
            var dirName = fullPath.Split('\\');
            var fileName = Path.GetFileName(fullPath); 
            if (fileName.Length > 25)
            {
                fileName = fileName.Substring(0, 15) + "..."+ fileName.Substring(fileName.Length - 5, 5);
            } 
            ellipsesPath = Path.GetPathRoot(fullPath) + (dirName.Length > 2 ?@"..\" : "") + fileName; 
            return ellipsesPath;
       }

and use it like this :

C#

string shortPath= GetShortPath(@"d:\tester\test\test\hi.bat");

C#

string pattern = @"(""[^\\]+\\)(?:[^\\""]+\\)*([^""]+"")";
string data = regedit.exe /e:a "D:\data\backup\laptop\CCleaner\CCleaner.reg" "HKEY_CURRENT_USER\Software\Piriform\CCleaner"
string replacement = "$1...\\$2";
Regex rgx = new Regex(pattern);
data = rgx.Replace("\"" + data + "\"", replacement);
data = data.TrimStart('"');
data = data.TrimEnd('"');
