Question

VB.net实现数值累加

就是每Click一次button就将数值变量（如num）加1。请给代码

Answer 1

楼上的代码里面num应该在click事件外定义，否则每次单击时num的值都会重新定义

Answer 2

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Static num As Integer = 0
num += 1
Label1.Text = num.ToString() End Sub
