C# equivalent to Java resource

Question

Is there an online resource or database that allows looking up the C# equivalent to a Java class and vice versa?

I have been porting code and have been Googling individual classes one at a time; it gets a little tedious. 8^j

something as simple as this: http://www.harding.edu/fmccown/java_csharp_comparison.html

or more about the libraries available on each?
