[VB.Net]判斷變數是否改變

其實這個功能我找了好久，因為我是從Indusoft撰寫程式跳到真正的程式語言，所以很依賴這個功能，每當某變數有啥變動時，就執行那些指令。

在Google大神下用中文搜尋超久，一直沒有我要的答案。後來用英文的方式搜尋，果真有我要的....這時候真的覺得  會英文真好~~~哈

目前找到的版本如下，有點麻煩~~但還可以接受

Public Class Form1
    Private WithEvents test As New myVar

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        test.Variable = TextBox1.Text
    End Sub
    Private Sub VariableChanged(ByVal NewValue As String) Handles test.VariableChanged
        MessageBox.Show(NewValue)
    End Sub
End Class

Public Class myVar
    Private mValue As String
    Public Event VariableChanged(ByVal mvalue As String)
    Public Property Variable() As String
        Get
            Variable = mValue
        End Get
        Set(ByVal value As String)
            mValue = value
            RaiseEvent VariableChanged(mValue)
        End Set
    End Property
End Class
