刚看完正则语法，怎么在 VB.Net中使用正则表达式，举个简单例子就可以了。
比如只允许编辑框输入数字.代码怎么写?

Imports System.Text.RegularExpressions

Public Class Validate
Private _Regex As Regex
Private _Flag As Boolean

Private Sub Validate(ByVal tmpInfo As String, ByVal tmpRegular As String)
Try
Me._Regex = New Regex(tmpRegular)
Me._Flag = Me._Regex.IsMatch(tmpInfo)
Catch
Me._Flag = False
End Try
End Sub

Public ReadOnly Property ValidateIp(ByVal Ip As String) As Boolean
Get
Me.Validate(Ip, "^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$ ")
Return Me._Flag
End Get
End Property

End Class
