VB.NET := Operator

What does the following mean?

Class.Function(variable := 1 + 1)

What is this operator called, and what does it do?

It assigns the optional parameter "variable" the value 2.

It is used to assign optional variables, without assigning the previous ones.

sub test(optional a as string = "", optional b as string = "")
   msgbox(a & b)
end sub

you can now do

test(b:= "blaat")
'in stead of
test("", "blaat")

VB.NET supports this syntax for named (optional) parameters in method calls. This particular syntax informs Class.Function that its parameter variable is to be set to 2 (1 + 1).
