线程异步调用

Thread objThread = new Thread(new ThreadStart(delegate

            {

                Dispatcher.BeginInvoke(new Action(() =>--解决调用线程必须为 STA，因为许多 UI 组件都需要的问题

                {

                    ReportViewer rp = ReportingServiceHelper.GetReportView(reportName, null, true, true);

                    rp.RefreshReport();

                    CurrentView = ReportingServiceHelper.GetFormHost(rp);

                }));

}));

            objThread.Start();

调用控件的BeginInvoke实现异步

///

         /// 线程调用BeginInvoke          ///

         private void ThreadBeginInvoke()
         {
             listBox1.Items.Add("--begin--");
             new Thread(() =>
             {
                 Thread.CurrentThread.Name = "ThreadBeginInvoke";
                 Thread.Sleep(10000);
                 string temp = "Before!";
                 listBox1.BeginInvoke(new Action(() =>
                 {
                     this.listBox1.Items.Add(temp + ":" + Thread.CurrentThread.Name);
                 }));
                 temp += "After!";
             }).Start();
             Thread.Sleep(1000);
             listBox1.Items.Add("--end--");
         }

委托实现异步

public delegate int AddOp(int x, int y);

class Program

{

static void Main(string[] args)

{

Console.WriteLine("******* 委托异步线程
两个线程“同时”工作 *********");

//显示主线程的唯一标示

Console.WriteLine("调用Main()的主线程的线程ID是：{0}.", Thread.CurrentThread.ManagedThreadId);

//将委托实例指向Add()方法

AddOp pAddOp = new AddOp(Add);

//开始委托次线程调用。委托BeginInvoke()方法返回的类型是IAsyncResult，

//包含这委托指向方法结束返回的值，同时也是EndInvoke()方法参数

IAsyncResult iftAR = pAddOp.BeginInvoke(10, 10, null, null);

Console.WriteLine(""nMain()方法中执行其他任务…….."n");

int sum = pAddOp.EndInvoke(iftAR);

Console.WriteLine("10 + 10 = {0}.", sum);

Console.ReadLine();

}

//求和方法

static int Add(int x, int y)

{

//指示调用该方法的线程ID，ManagedThreadId是线程的唯一标示

Console.WriteLine("调用求和方法 Add()的线程ID是：
{0}.", Thread.CurrentThread.ManagedThreadId);

//模拟一个过程，停留5秒

Thread.Sleep(5000);

int sum = x + y;

return sum;

}

}

}
