如何使用this.Invoke方法传递多个参数给委托
下面是MSDN中的例子：
using System;using System.Drawing;using System.Windows.Forms;using System.Threading; public class MyFormControl : Form { public delegate void AddListItem(String myString); public AddListItem myDelegate; private Button myButton; private Thread myThread; private ListBox myListBox; public MyFormControl() { myButton = new Button(); myListBox = new ListBox(); myButton.Location = new Point(72, 160); myButton.Size = new Size(152, 32); myButton.TabIndex = 1; myButton.Text = "Add items in list box"; myButton.Click += new EventHandler(Button_Click); myListBox.Location = new Point(48, 32); myListBox.Name = "myListBox"; myListBox.Size = new Size(200, 95); myListBox.TabIndex = 2; ClientSize = new Size(292, 273); Controls.AddRange(new Control[] {myListBox,myButton}); Text = " 'Control_Invoke' example "; myDelegate = new AddListItem(AddListItemMethod); } static void Main() { MyFormControl myForm = new MyFormControl(); myForm.ShowDialog(); } public void AddListItemMethod(String myString) { myListBox.Items.Add(myString); } private void Button_Click(object sender, EventArgs e) { myThread = new Thread(new ThreadStart(ThreadFunction)); myThread.Start(); } private void ThreadFunction() { MyThreadClass myThreadClassObject = new MyThreadClass(this); myThreadClassObject.Run(); } } public class MyThreadClass { MyFormControl myFormControl1; public MyThreadClass(MyFormControl myForm) { myFormControl1 = myForm; } String myString; public void Run() { for (int i = 1; i <= 5; i++) { myString = "Step number " + i.ToString() + " executed"; Thread.Sleep(400); // Execute the specified delegate on the thread that owns // 'myFormControl1' control's underlying window handle with // the specified list of arguments. myFormControl1.Invoke(myFormControl1.myDelegate, new Object[] {myString}); } } }
