and i need get related path of second related with first like this:

..\\..\\Projectos2\\CSoft.Core

Exists a way to do this in c# or some one have a function can help me

Answer 1

Try MakeRelativeUri :

Uri first = new Uri(@"C:\Projectos2\CSoft.Core");
Uri second = new Uri(@"C:\Projectos\FrameworkCS\CSoft.Core ");

string relativePath = second.MakeRelativeUri(first).ToString();

Result:

"../../Projectos2/CSoft.Core"

Answer 2

I would probably figure it out by splitting both using the '\\' as a separator. I would then count array items that were the same to get my common bond. Then I would build the destination path using the remaining items in the destination array and build the ..\\ string by counting the remaining items in the source.

• Common path = C:\\Projectos\\
• Remaining destination path = CSoft.Core
• Remaining source path has 1 more item (not including the file name itself) giving you ..\\

Join the ..\\ with the CSoft.Core giving you ..\\CSoft.Core

Addendum: I didn't realise you could use the URI.MakeRelativePath() method for this - don't bother reinventing the wheel if it's already been done elsewhere.
