[VB.NET]这段代码错在哪?关于soundplayer类的

这段代码错在哪?关于soundplayer类的 Public a11 As New Soundplayer Private Sub Form1_Load(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles MyBase.Load a11.soundLocation = d:/tishi.wav a11.Load() a11.Play() End Sub Sub a2() Handles a11.LoadCompleted End Sub 结果在 sub a2 中提示 Handles子句要求一个在包含类型或它的某个基类型中定义WithEvents变量,错在哪了? __________________________________________________________________________ all定义错误 Public WithEvents a11 As Soundplayer __________________________________________________________________________ 谢谢,是我概念不清楚,呵呵. __________________________________________________________________________
