Calling method with "out" parameter from dynamically loaded dll? [duplicate]

This question already has an answer here:

• Why can't I retrieve the value for parameters of type out or ref using Type.InvokeMember? 3 answers

I'm using reflection to load my dll. I can call its methods, get its parameters, etc. But can't figure out how to call a method that has an out parameter. Here's an example of a method I'm trying to call

Dll out method

public void GetNumber(out int number)
{
    ......
    number = 5;
}

I tried with the following, but number value is not changing.

int number = 0;
myType.InvokeMember("GetNumber", BindingFlags.InvokeMethod | BindingFlags.Instance | BindingFlags.Public, null, myInstance, new object[] { number });

How can I achive this?
