隐藏窗体制作托盘

综合网上的前辈的资料，自己经过琢磨整理代码如下：

using System.Windows.Forms;
using System.Data;

        private System.Windows.Forms.MenuItem menuItem2;

        public Form1()
        {
            //
            // Windows 窗体设计器支持所必需的

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }

        /**//// <summary>

        protected override void Dispose( bool disposing )
        {
            if( disposing )
            {
                if (components != null) 
                {

                }
