Convert C# codes to VB.NET

[Steve]

Dear All,
Try to understand the following C# codes. Can someone help me convert the
following codes to VB.NET? What is the meaning of += in C#?

public void InstantiateIn(Control container)
}
LiteralControl l = new LiteralControl();
l.DataBinding += new EventHandler(this.OnDataBinding);
container.Controls.Add(l);
}

Public void OnDataBinding(object sender, EventArgs e)
{
......
}

Thanks,
Steve

x += y is equivalent to x = x + y in C# or VB.NET.

However, C# supports operator overloading (letting you redefine the
meaning of +, for example, for a class), and sometimes language
designers get clever and use operator overloading for something that's
not especially intuitive. See C++ stream operations for the cannonical
example (they work by overloading the bit shifting operators).

The VB.NET equivalent of this line is

AddHandler l.DataBinding, Addressof(this.OnDataBinding)
