委托 调用的函数带参数 如何实现？？

Question

委托事件中调用的函数中还有函数调用，且带参变量，但这种方法无法执行，请问采取什么样的方法能够解决这样的问题？？
        private delegate void CallData();//定义委托
        System.Timers.Timer timer = new System.Timers.Timer();//全局监控计时器        void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            this.Data();
            //throw new NotImplementedException();
        }        #region 自定义函数
        void Data()
        {
            // InvokeRequired需要比较调用线程ID和创建线程ID
            // 如果它们不相同则返回true
            if (A101.InvokeRequired)
            {
                CallData cd = new CallData(this.setdata);
                this.BeginInvoke(cd);
            }
            else
            {
                this.setdata();
            }
        }
        void setdata()
        {
            this.DataShow(A101, t101, (clsE3)DeviceE3Var.LstE3[163], true);//A101：控件名称        }
       public void DataShow(ControlLibrary.Labels lab, ControlLibrary.Titles title, clsE3 e3tmp, Boolean e3run)
        {
            title.Model = true;
            if (e3run == true)//设备启动e3运行
            {
                lab.Lab1 = Convert.ToString(e3tmp.JianShi[4]); //平均电流
                lab.Lab2 = Convert.ToString(e3tmp.JianShi[9]); //已用热容量百分比
                lab.Lab3 = Convert.ToString(e3tmp.JianShi[11]); //电流不平衡百分比
             }
            else//设备停止运行
            {
                lab.Lab1 = "0";
                lab.Lab2 = "0";
                lab.Lab3 = "0";
            }
        }

private void btnOcr_Click(object sender, EventArgs e)
        {
            this.Enabled = false;
            //funOcr(imageViewer1.ImageSouce);
            this.progressBar1.Maximum = imageViewer1.ImageSouce.Length *2+ 5;
            dlgtOCR dg = new dlgtOCR(funOcr);

        }
        void funCallBack(IAsyncResult ia)
        {

            }
            else
            {
                if (i < progressBar1.Maximum)
                {
                    progressBar1.Visible = true;
                    label2.Visible = true;
                    this.progressBar1.Value = i;

                }
                else

                    progressBar1.Visible = false;
                    label2.Visible = false;
                }
            }
        }        delegate void dlgtOCR(string[] strImg);
        delegate void dlgtShowMessage(string strIn, Control ct);
        delegate void dlgtShowBar(int i,string mesg);
        delegate void dlgtEndOcr();
 private void funOcr(string[] strImg)
        {
}

通过Data() 可直接访问类内部的对象，无需再额外传递参数。例如：
       private int k = 0;              ///这是我定义的一个新的字段    
        private delegate void CallData();//定义委托 
        System.Timers.Timer timer = new System.Timers.Timer();//全局监控计时器         void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
        { 
            this.Data(); 
            //throw new NotImplementedException(); 
        }         #region 自定义函数 
        void Data() 
        {             k = 20;       //使用这个字段。
            // InvokeRequired需要比较调用线程ID和创建线程ID 
            // 如果它们不相同则返回true 
            if (A101.InvokeRequired) 
            { 
                CallData cd = new CallData(this.setdata); 
                this.BeginInvoke(cd); 
            } 
            else 
            { 
                this.setdata(); 
            } 
        } 从上面推荐你可以看出来怎么做了。

Answer 3

delegate void dlgtOCR(string[] strImg);
 dlgtOCR dg = new dlgtOCR(funOcr);
 dg.BeginInvoke(imageViewer1.ImageSouce,null,null);
上面的红色部分就是参数这个简单的委托示例,

delegate void dlgtOCR(string[] strImg);
 dlgtOCR dg = new dlgtOCR(funOcr);
 dg.BeginInvoke(imageViewer1.ImageSouce,null,null);

Answer 6

    public partial class Form5 : Form
    {
        public Form5()
        {
            InitializeComponent();
        }        private delegate void CallData();        private void button1_Click(object sender, EventArgs e)
        {
            this.Data();
        }        void Data()
        {
            CallData cd = new CallData(this.setData);
            this.BeginInvoke(cd);
        }        void setData()
        {
            this.DataShow(this.textBox1.Text);
        }        public void DataShow(string s)
        {
            this.textBox2.Text = s;
        }
       
    }
委托事件中也是可以有函数的，参照以上。
