Question

This question is not about managing Windows pathnames; I used that only as a specific example of a case-insensitive string. (And I if I change the example now, a w

A shorter and more lightweight approach might be to create an extension method:

public static class StringExt
{
    public static bool IsSamePathAs(this string @this, string other)
    {
        if (@this == null)
            return other == null;

        if (object.ReferenceEquals(@this, other))
            return true;

        // add other checks
        return @this.Equals(other, StringComparison.OrdinalIgnoreCase);
    }
}

This requires far less coding than creating a whole separate class, has no performance overhead (might even get inlined), no additional allocations, and also expresses the intent pretty clearly IMO:

var arePathsEqual = @"c:\test.txt".IsSamePathAs(@"C:\TEST.txt");
