vb.net - VB 2010 中的 Select Case 的多个条件

Question

我试图弄清楚如何测试案例陈述中的两个条件。

Select Case txtWeight.Text
     Case Is <= 2
        decShippingCost = (decShipping2 + (decShipping2 * 0.26))
     Case Is > 2 and <= 4
        decShippingCost = (decShipping4 + (decShipping4 * 0.026))

我无法开始工作，我做错了什么？

Answer 1

Select Case txtWeight.Text
    Case Is <= 2
        decShippingCost = (decShipping2 + (decShipping2 * 0.26))
    Case 3 to 4
        decShippingCost = (decShipping4 + (decShipping4 * 0.026))
End Select

或者如果你想将 2.5 捕获为 >2，也可以这样。

Select Case txtWeight.Text
    Case Is <= 2
        decShippingCost = (decShipping2 + (decShipping2 * 0.26))
    Case 2.01 to 4
        decShippingCost = (decShipping4 + (decShipping4 * 0.026))
End Select
