How to check if a class implements an interface without navigating through its inheritance tree?

If I want to know if a class inherits IDisposable I have to Go To Definition in each of its parent classes and interfaces?

Isn'开发者_运维技巧t there an easier way?

Put an instance of the class in question in a using statement. The compiler will tell you if it is possible with that class or not.

If you have resharper installed, you can use type hierarchy (Crl + E, H) to view it quickly.

bool implementsIDisposable = (classInstance is IDisposable);
