Question

I have an asp.net url path which is being generated in a web form, and is coming out something like ‘/foo/bar/../bar/path.aspx’, and is coming out in the generated html like this too. It should be shortened to ‘/foo/bar/path.aspx’.

Path.Combine didn’t fix it. Is there a function to clean this path up?

You could create a helper class which wrapped the UriBuilder class in System.Net

public static class UriHelper {            public static string NormalizeRelativePath(string path)     {         UriBuilder _builder = new UriBuilder('http://localhost');         builder.Path = path;         return builder.Uri.AbsolutePath;     } } 

which could then be used like this:

string url = 'foo/bar/../bar/path.aspx'; Console.WriteLine(UriHelper.NormalizeRelativePath(url)); 

It is a bit hacky but it would work for the specific example you gave.
