The Select...Case statement in Visual Basic provides an alternative to nested If/Then/ElseIf statements. It allows a single test expression to be evaluated and, if a match is found, the associated block of code is executed. If no matches are found, the optional Case Else statement will execute. The syntax includes the Select Case statement followed by the test expression, multiple Case statements listing possible expression matches and the associated code blocks, and an optional Case Else statement. An example demonstrates using a Select Case statement to evaluate a test score stored in a variable and output the corresponding grade in a message box.
