I'm creating a function where I need to pass an object so that it can be modified by the function. What is the difference between:

public void myFunction(ref MyClass someClass)

and

public void myFunction(out MyClass someClass)

Which should I use and why?!

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
