    //例一 delegate void AppendStringCallback(string text); private void AppendString(string txt) { this.listView1.Items.Add(txt); } private void ReceiveDate() { AppendStringCallback appendStringCallback = new AppendStringCallback(AppendString); this.Invoke(appendStringCallback, new object[] { string.Format("{0},{1},{2}", str1, str2 + "号", iepAddress.ToString()) }); } //例二 namespace ThreadPoolDemo { public partial class ThreadForm : Form { // 定义delegate以便Invoke时使用 private delegate void SetProgressBarValue(int value); // 跟SetProgressBarValue委托相匹配的方法 private void SetProgressValue(int value) { progressBar.Value = value; } // 使用Invoke方法来设置进度条 private void RunWithInvoke() { int value = progressBar.Value; while (value< progressBar.Maximum) { //如果是跨线程调用 if (InvokeRequired) { this.Invoke(new SetProgressBarValue(SetProgressValue), value++); } else { progressBar.Value = ++value; } } } public ThreadForm() { InitializeComponent(); } private void btnInvoke_Click(object sender, EventArgs e) { progressBar.Value = 0; Thread thread = new Thread(new ThreadStart(RunWithInvoke)); thread.Start(); } } }
