异步调用开发应用总结（WCF）

上一篇随笔的异步调用是方法的异步调用实现，WCF的异步调用有自己的实现逻辑（一些方法和调用过程.net已经制定好）

WCF异步调用示例：

客户端调用：

            AsyncManageAgent clientAgent = this.Command as AsyncManageAgent;
            clientAgent.GetNameAsync(Code, userState);
            clientAgent.GetNameCompleted += delegate(object sender, Agent.GetNameCompletedEventArgs args)
            {

                this.GetNameCompleted(this, new GetNameCompletedEventArgs(args.results,args.Error,args.Cancelled,args.UserState));
            };

WCF代理类（异步调用）

        private System.IAsyncResult OnBeginGetName(object[] inValues, System.AsyncCallback callback, object asyncState)
        {
            string Code = inValues[0].ToString();
            return this.BeginGetName(Code, callback, asyncState);
        }

        //onEnd
        private object[] OnEndGetName(System.IAsyncResult result)
        {
            string retVal = this.EndGetName(result);
            return new object[] {
                    retVal};
        }

        //OnCompleted
        private void OnGetNameCompleted(object state)
        {
            if ((this.GetNameCompleted != null))
            {
                InvokeAsyncCompletedEventArgs e = ((InvokeAsyncCompletedEventArgs)(state));
                this.GetNameCompleted(this, new GetNameCompletedEventArgs(e.Results, e.Error, e.Cancelled, e.UserState));
            }
        }
        //Async方法
        public void GetNameAsync(string Code)
        {
            this.GetNameAsync(Code, null);
        }

        public void GetNameAsync(string Code, object userState)
        {
            if ((this.onBeginGetNameDelegate == null))
            {
                this.onBeginGetNameDelegate = new BeginOperationDelegate(this.OnBeginGetName);
            }
            if ((this.onEndGetNameDelegate == null))
            {
                this.onEndGetNameDelegate = new EndOperationDelegate(this.OnEndGetName);
            }
            if ((this.onGetNameCompletedDelegate == null))
            {
                this.onGetNameCompletedDelegate = new System.Threading.SendOrPostCallback(this.OnGetNameCompleted);
            }
            base.InvokeAsync(this.onBeginGetNameDelegate, new object[] {
                        Code}, this.onEndGetNameDelegate, this.onGetNameCompletedDelegate, userState);
        }

关于服务端具体实现，服务部署配置等需要另写博客，待续。。
