IIf Function
Returns one of two objects, depending on the evaluation of an expression.
Public Function IIf( _ ByVal Expression As Boolean, _ ByVal TruePart As Object, _ ByVal FalsePart As Object _ ) As Object
Parameters
- Expression
-
Required. Boolean. The expression you want to evaluate.
- TruePart
-
Required. Object. Returned if Expression evaluates to True.
- FalsePart
-
Required. Object. Returned if Expression evaluates to False.
The IIf function provides a counterpart for the ternary Conditional Operator: ? : in Visual C++.
This example uses the IIf function to evaluate the testMe parameter of the checkIt procedure and returns the word "Large" if the amount is greater than 1000; otherwise, it returns the word "Small".
Function checkIt(ByVal testMe As Integer) As String Return CStr(IIf(testMe > 1000, "Large", "Small")) End Function
Note that if Option Strict is On, you must use the CStr keyword to explicitly convert the return from Object to String.
