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

Question

I have 2 DirectoryInfo objects and want to check if they are pointing to the same directory. Besides comparing their Fullname, are there any other better ways

Answer 1

Case-insensitive comparison is the best you can get. Extract it to a helper class just in case mankind comes up with a better method.

public static class DirectoryInfoExtensions
{
    public static bool IsEqualTo(this DirectoryInfo left, DirectoryInfo right)
    {
        return left.FullName.ToUpperInvariant() == right.FullName.ToUpperInvariant();
    }
}

and use:

if (di1.IsEqualTo(di2))
{
    // Code here
}
