Select Case Statement Select Case is similar to If..Then..Else statement. Select Case allows us to do various comparisions against one variable that we use throughout the whole statement. Select Case is cleaner and easier to understand if you are continually comparing against one variable.
The following sample asks the user to enter a vowel in a textbox and checks the value entered using the the Select Case statement and if true displays some text.
Private Sub IfThen_Click(ByVal sender As System.Object, ByVal e_
As System.EventArgs) Handles IfThen.Click
If CInt(TextBox1.Text) = 1 Then
Label1.Text = "You entered" & CInt(TextBox1.Text)
ElseIf CInt(TextBox1.Text) = 2 Then
Label1.Text = "You entered" & CInt(TextBox2.Text)
ElseIf CInt(TextBox1.Text) = 3 Then
Label1.Text = "You entered" & CInt(TextBox2.Text)
Else
Label1.Text = "You entered another number"
End If
End Sub |
