        this.timer100 = new System.Windows.Forms.Timer(this.components);
       this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.MainForm_FormClosing);
        this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.MainForm_FormClosed);
    }
private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
    {
        timer100.Stop();

    }
private void MainForm_FormClosed(object sender, FormClosedEventArgs e)
    {
        timer100.Dispose();
        timer100 = null;
    }

我没有像注释中提到的jhmt那样将InitializeComponent()放入MainForm的构造函数中。
