How to check whether 2 DirectoryInfo objects are pointing to the same directory?

var dirUserSelected = new DirectoryInfo(Path.GetDirectoryName("SOME PATH"));
var dirWorkingFolder = new DirectoryInfo(Path.GetDirectoryName("SAME PATH AS ABOVE"));

if (dirUserSelected == dirWorkingFolder)
{ 
   //this is skipped 
}

if (dirUserSelected.Equals(dirWorkingFolder))
{ 
   //this is skipped 
}

Whilst debugging, I can examine the values in each and they ARE equal. So i’m guessing this is another byval byref misunderstanding… Please someone, how do I compare these two things?

I believe you want to do this :

var dirUserSelected = new DirectoryInfo(Path.GetDirectoryName(@"c:\some\path\"));
var dirWorkingFolder = new DirectoryInfo(Path.GetDirectoryName(@"c:\Some\PATH"));

if (dirUserSelected.FullName  == dirWorkingFolder.FullName )
{ // this will be skipped, 
  // since the first string contains an ending "\" and the other doesn't
  // and the casing in the second differs from the first
}

// to be sure all things are equal; 
// either build string like this (or strip last char if its a separator) 
// and compare without considering casing (or ToLower when constructing)
var strA = Path.Combine(dirUserSelected.Parent, dirUserSelected.Name);
var strB = Path.Combine(dirWorkingFolder.Parent, dirWorkingFolder.Name);
if (strA.Equals(strB, StringComparison.CurrentCultureIgnoreCase)
{ //this will not be skipped 
}

In you example you are comparing 2 different objects thats why they are not equal. I believe you need to compare Paths so use the code above.
