VB.NET里的委托
一段C#代码想成VB.NET时，却有错误
C#代码ShowMsg.cs里只有一句

public delegate void ShowMsg(string strMsg);

类Connection.cs里

    public class Connection
    {
        string strPath;
        ShowMsg showMsg;
        ShowMsg removeConnection;
        Thread threadMsg;
        bool isWait = true;
...
        public Connection(string strPath, ShowMsg showMsg, ShowMsg removeConnection)
        {
...
            this.strPath = strPath;
            this.showMsg = showMsg;
            this.removeConnection = removeConnection;

            this.threadMsg = new Thread(WaitMsg);
            this.threadMsg.IsBackground = true;
            this.threadMsg.Start();
...
        }

        void WaitMsg()
        {
            while (isWait)
            {
                try
                {
                    ... 
                    showMsg(strMsg);
                }
                catch (Exception ex)
                {
                    ... 
                    removeConnection(strMsg);
                }
            }
        }
...

上述代码改成VB.NET后，WaitMsg里的showMsg(strMsg)和removeConnection(strMsg)这两句，都提示错误“表达式不是方法”，为什么？应该怎么改才正确，谢谢。
VB.net?委托 vb.net ，委托? 委托
[解决办法]

Public Class ShowMsg
    Public Delegate Sub ShowMsg(ByVal strMsg As String)
End Class

去掉Public Class ShowMsg 和 End Class
