Say I have a struct:
struct MyStruct
{
public int X
public int Y
}
And a method in some class that is iterated over many times elsewhere:
public bool MyMethod( MyStruct myStruct )
{
return ...
}
Is changing the MyMethod signature to the following an acceptable optimization?
public bool MyMethod( ref MyStruct myStruct )
If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?
