Emit byref parameters

Harley Lagunov

How can I define/emit parameter type which is passed byref?
for example:
void MyFunc(ref MyClass myClass)
{
}

I can define/emit "System.Int32&" type, but can't '"SomeNamespace.MyClass&"?

I don't have the answer, instead I have an additional, related question:
How can I define/emit OUT parameter types with reflection emit?

Make it a ref parameter, and then tag it with the
System.Runtime.InteropServices.OutAttribute.

To get a byref type, use Type.GetType() (or similar GetType method)
and append an "&" at the end of the type name.

If I try to use Type.GetType("MyNamespace.MyClass&") - returns null.
Type.GetType("System.Int32&") - returns int32& :((

Problem is solved:
Following code works fine - getting type from module where type defined:
//for pointer, array, byref types of types
private Type GetByRefType(Type type)
{
string clsName = type.FullName+"&"; //[], or *
Module mod = type.Module;
return mod.GetType(clsName);
}
