Does C# have the equivalent of Java's java.lang.RuntimeException?

SystemException is the equivalent, it is the base class of all exceptions that can be raised by .NET code. As opposed to application exceptions.

From the comments it however sounds like you want to catch this exception. In which case you should never use SystemException, you'll catch too many. Make your own exception class, derived from Exception.

There are no exception specifications in .NET, in case that's what you're after.
