One line if in VB .NET

Question

Is it possible to do one line if statement in VB .NET? If so, how?

Answer 1

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

• Is there a conditional ternary operator in VB.NET?

• Orcas introduces the IF operator - a new and improved IIF

Answer 2

It's actually pretty simple..

If CONDITION Then ..INSERT CODE HERE..

Answer 3

Single line

Syntax:

If (condition) Then (do this)

Example:

If flag = true Then i = 1

Multiple ElseIf's

Syntax:

If (condition) Then : (do this)
ElseIf (condition2) Then : (do this)
Else : (do this)
End If

OR

If (condition) Then : (do this) : ElseIf (condition2) Then : (do this) : Else : (do this) : End If

Multiple operations

Syntax:

If (condition) Then : (do this) : (and this) : End If

Answer 4

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
