One line if in VB .NET

Use IF().

It is a short-circuiting ternary operator.

Dim Result = IF(expression,<true return>,<false return>)

• IIF becomes If, and a true ternary operator

It's actually pretty simple..

If CONDITION Then ..INSERT CODE HERE..

At the risk of causing some cringing by purests and c# programmers, you can use multiple statements and else in a one-line if statement in VB. In this example, y ends up 3 and not 7.

i = 1
If i = 1 Then x = 3 : y = 3 Else x = 7 : y = 7

Or

IIf(CONDITION, TRUE_ACTION, FALSE_ACTION)

Just add Then:

If A = 1 Then A = 2

or:

If A = 1 Then _
    A = 2

You can use the IIf function too:

CheckIt = IIf(TestMe > 1000, "Large", "Small")

If (condition, condition_is_true, condition_is_false)

It will look like this in longer version:

If (condition_is_true) Then 

Else (condition_is_false)

End If
