More informative comparison of objects in C#

In my C# testing, I often want to compare two objects of the same type (typically an expected object against the actual object), but I want to allow for some flexibility. For example, there may be timestamp fields that I know can't be equal or some fields that I just want to ignore when comparing the objects. I also want to provide an informative message that describes where the two object properties' values differ in order that I can quickly identify what the problem is.

The standard Equals and Comparer methods just seem to return ints or Booleans which don't provide enough information for me. At the moment, my object comparison methods return a custom type that has two fields (a boolean and a message), but my thinking is that there must be a more standard way to do this. These days, perhaps a Tuple might be the way to go, but I would welcome suggestions.
