正则，可以用NET自带的正则控件，也可以使用JS。

如果是输入的时候就控制不允许输入，那可以使用JS或者Ajax.Net的FilteredTextBox

如果是输入后想验证的话，那就用验证控件，很方便

放一个CompareValidator，
OPERATOR设置为：DataTypeCheck，然后TYPE：Integer，这算不算？

Private nonNumberEntered As Boolean = False

Private Sub textBox1_KeyDown(sender As Object, e As _
System.Windows.Forms.KeyEventArgs) _
Handles textBox1.KeyDown
nonNumberEntered = False

If e.KeyCode < Keys.D0 OrElse e.KeyCode > Keys.D9 Then
If e.KeyCode < Keys.NumPad0 OrElse e.KeyCode > Keys.NumPad9 Then
If e.KeyCode <> Keys.Back Then
nonNumberEntered = True
End If
End If
End If
End Sub


---------------------------------------------------------------------------- Private Sub textBox1_KeyPress(sender As Object, e As _
System.Windows.Forms.KeyPressEventArgs) _
Handles textBox1.KeyPress
If nonNumberEntered = True Then
e.Handled = True
End If
End Sub
End Class

就是上面的这两段代码,一个KeyDown事件,一个KeyPress事件,联合起来用.
(代码帖出来有点乱)
