Calling Base Class' Ctor

[BDB]

Hi,

I'm trying to call a base class' constructor. This is giving me an error:
Use of keyword 'base' is not valid in this context.

....

public class B : A
{
B( int i )
{
base( i ) //Calling A's ctor of same declaration
}
}


Thanks,
Bryan

You have to call it before the function body, like so:
public class B : A
{
B( int i ) : base( i )
{
}
}

Good luck,
Jared

Found it.

public class B : A
{
B( int i ) : base( i ) {}
}

I see you've found the answer to this one - but if you have any other
