No. For reference types, you are passing a reference already, there is no need to pass the reference by reference unless you want to change what the reference points to, e.g. assign it a new object. For value types, you can pass by reference, but unless you have a performance problem, I wouldn't do this. Especially if the types in question are small (4 bytes or less), there is little or no performance gain, possibly even a penalty.
