}这里ContextMenuStrip菜单的鼠标右击事件没有动作.谢谢!

Answer 1

 niInfo
是什么打断点查

Answer 2

初步怀疑是Main_Load事件里出的问题,但是不太确定到了什么问题,请高手指点.谢谢

Answer 3

你是不是要添加托盘图标的右键菜单?如果是的话,NotifyIcon本身有个属性:contextMenuStrip,填入你要弹出的菜单就OK了.你现在的问题可能的原因: 你要弹出的menu没有声明吧?

Answer 4

要把Designer的代码贴出来才知道。。

Answer 5

Designer代码如下:namespace RemoteControl
{
    partial class Form1
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }        #region Windows 窗体设计器生成的代码        /// <summary>
        /// 设计器支持所需的方法 - 不要
        /// 使用代码编辑器修改此方法的内容。
        /// </summary>
        private void InitializeComponent()
        {
            this.components = new System.ComponentModel.Container();
            System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));
            this.niInfo = new System.Windows.Forms.NotifyIcon(this.components);
            this.Stop = new System.Windows.Forms.ToolStripMenuItem();
            this.Restart = new System.Windows.Forms.ToolStripMenuItem();
            this.Exit = new System.Windows.Forms.ToolStripMenuItem();
            this.Menu = new System.Windows.Forms.ContextMenuStrip(this.components);
            this.Menu.SuspendLayout();
            this.SuspendLayout();
            // 
            // niInfo
            // 
            this.niInfo.ContextMenuStrip = this.Menu;
            this.niInfo.Icon = ((System.Drawing.Icon)(resources.GetObject("niInfo.Icon")));
            this.niInfo.Text = "notifyIcon1";
            this.niInfo.Visible = true;
            // 
            // Stop
            // 
            this.Stop.Name = "Stop";
            this.Stop.Size = new System.Drawing.Size(152, 22);
            this.Stop.Text = "停止";

            this.Restart.Text = "重启";
            //

            // 
            this.Exit.Name = "Exit";
            this.Exit.Size = new System.Drawing.Size(152, 22);
            this.Exit.Text = "退出";
            this.Exit.Click += new System.EventHandler(this.Exit_Click);
            // 
            // Menu
            // 
            this.Menu.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
            this.Stop,
            this.Restart,
            this.Exit});
            this.Menu.Name = "Menu";
            this.Menu.Size = new System.Drawing.Size(153, 92);
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(305, 254);
            this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.Name = "Form1";
            this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
            this.Text = "Main";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.VisibleChanged += new System.EventHandler(this.Form1_VisibleChanged);
            this.Menu.ResumeLayout(false);
            this.ResumeLayout(false);        }        #endregion        private System.Windows.Forms.NotifyIcon niInfo;
        private System.Windows.Forms.ContextMenuStrip Menu;
        private System.Windows.Forms.ToolStripMenuItem Stop;
        private System.Windows.Forms.ToolStripMenuItem Restart;
        private System.Windows.Forms.ToolStripMenuItem Exit;
    }
}我试过了注释掉Main_Load事件里的StartListener()方法就没有问题.

Answer 6

        private void Main_Load(object sender, EventArgs e) 
        { 
            StartListener(); 
        } 
        private void StartListener() 
        { 
            TcpListener listener; 
            try 
            { 
                listener = new TcpListener(60000); 
            } 
            catch 
            { 
                Console.WriteLine("Falt to Creat Listener Port"); 
                return; 
            } 
            listener.Start(); 
            bool loop = true; 
            while (loop) 
            { 
                Socket s = listener.AcceptSocket(); 
                NetworkStream ns = new NetworkStream(s); 
                StreamReader r = new StreamReader(ns); 
                string command = r.ReadLine(); 
                StreamWriter sw = new StreamWriter(command); 
                sw.WriteLine(); 
                s.Close(); 
            } 
        } while (loop) 
你的窗体一启动就进入了死循环。。窗体一直在做事~！！！你给这个StartListener()加一个线程吧。        private void Main_Load(object sender, EventArgs e) 
        { 
           System.Threading.Thread thread = new System.Threading.Thread(StartListener);
           thread.IsBackground = true;
           thread.Start();
        }
