Question

请问各位高手,如何让vb.net达到这样一种效果

令A=4
此时在text中读入一个数据5，使用if判断5>4，那么咋样才能让A返回TEXT中，输出出来呢

Answer 1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TextBox1.Text = "5"
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim A As Integer = 4
Dim B As Integer
B = CInt(TextBox1.Text)
If B > A Then TextBox1.Text = A.ToString()
End Sub

只想说这个仅仅需要用if语句就可以了，而且如果这个都要问的话，建议你还是先把vb.net基础书籍看完。。。
