基于事件的异步模式 (EAP),在该模式中异步操作由名为“操作名称Async”和“操作名称Completed”的方法/事件对(例如 WebClient.DownloadStringAsync 和 WebClient.DownloadStringCompleted...Net 2.0 开始出现, 同时在 Silverlight 中大量出现, 这种异步模式以 “操作名称Async” 函数和 “操作名称Completed” 事件成对出现为特征, 以 WebClient 的 DownloadStringAsync...source.SetException(args.Error); return; } source.SetResult(args.Result); }; webClient.DownloadStringAsync
InitializeComponent(); WebClient client = new WebClient(); client.DownloadStringAsync
"entitySet","'Test'") .AddQueryOption("propertyName","'Test'"); WebClient wc = new WebClient(); wc.DownloadStringAsync
} } 3.用linq读取 WebClient client = new WebClient(); client.DownloadStringAsync
string DownloadString(string address), string DownloadString(uri address) #method we will use DownloadStringAsync...Method void DownloadStringAsync(uri address), void DownloadStringAsync(uri address, Sy...

wb.DownloadStringCompleted += (sender, e) => RetrievLdModulesCallBack(BuildLdModules(e)); wb.DownloadStringAsync
c.DownloadStringAsync(uri); } } 火星标转换为84方法代码: /// /// 火星转84 /// 该方法经过实战测试计算比较准确 naki
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.DownloadStringAsync
WebClient(); 26 client.DownloadStringCompleted += completedHandler; 27 client.DownloadStringAsync
代码使用也非常简单: var client = new HttpClient(); string response = await client.DownloadStringAsync("https:/
Console.WriteLine(e.Result.Substring(0,100)); }; client.DownloadStringAsync...Console.ReadLine(); } } } 在上述事例中,对于同步方法DownloadString,提供了一个异步变体方法DownloadStringAsync
Pattern 值的是类似于 xxxxxxxAsync() 和 类似于event xxxxxCompleteHander 通过一个方法和一个完成事件来处理异步操作 .net中的例子: WebClient.DownloadStringAsync
client.DownloadString(url); } } 注意我们web service中的DownloadContent方法调用的是WebClient的同步方法,WebClient也有异步方法即:DownloadStringAsync
