Public Class VBObject
Public Function Hello() As String

前端頁面叫用
VB用法
'呼叫C#類別
Protected Sub btnCSharp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCSharp.Click
Dim myCSharpObject As New CSharpObject
txtMsg1.Text = myCSharpObject.Hello()
End Sub
'呼叫VB類別
Protected Sub btnVB_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnVB.Click
Dim myVBObject As New VBObject
txtMsg2.Text = myVBObject.Hello()
End Sub

CS用法　
//呼叫C#類別
protected void btnCSharp_Click(object sender, EventArgs e)
{
CSharpObject myCSharpObject = new CSharpObject();
txtMsg1.Text = myCSharpObject.Hello();
}
//呼叫VB類別
protected void btnVB_Click(object sender, EventArgs e)
{
VBObject myVBObject = new VBObject();
txtMsg2.Text = myVBObject.Hello();
}
