1.引用命名空间

using System.Runtime.Remoting.Messaging;

2.定义委托方法
/// <summary>
/// 带参数异步委托
/// </summary>
/// <param name="parameter1"></param>
/// <returns></returns>
delegate Guid MyMutilParamsDelegate(Guid parameter1);

3.创建中转对象
public class MyTask
{
 public MyTask()
 {
 }
 public Guid Test(Guid vGuid)
 {
  return vGuid;
 }
}

4.异步调用
public void UpdateVisitorTime(Guid visitorguid)
{
 MyTask t = new MyTask();
 MyMutilParamsDelegate mutilParams = new MyMutilParamsDelegate(t.Test);
 mutilParams.BeginInvoke(visitorguid, new AsyncCallback(UpdateTime), null);
}

5.Callback

private void UpdateTime(IAsyncResult result)
{
 AsyncResult async = (AsyncResult)result;
 MyMutilParamsDelegate DelegateInstance = (MyMutilParamsDelegate)async.AsyncDelegate;
 Guid vGuid = DelegateInstance.EndInvoke(result);

 //其他处理
}
