Task 分为两种：<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">1) Task，表示可以执行一个异步操作，声明如下：<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">public class Task : IAsyncResult, IDisposable { }<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">2) Task<TResult>，表示可以执行带有返回值的异步操作，声明如下：<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">public class Task<TResult> : Task { }</p>
<p style="box-sizing: border-box; outline: 0; margin: 0 0 16px; padding: 0; font-family: "Microsoft YaHei", "SF Pro Display", Roboto, Noto, Arial, "PingFang SC", sans-serif; font-size: 16px; color: rgba(77, 77, 77, 1); line-height: 26px; overflow-x: auto; overflow-wrap: break-word">4. 异步方法的返回类型必须为 void、Task、Task<TResult> 中的其中一种。<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">1) void，表示无返回值，不关心异步方法执行后的结果，一般用于仅仅执行某一项任务，但是不关心结果的场景。<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">2) Task，表示异步方法将返回一个 Task 对象，该对象通常用于判断异步任务是否已经完成，可以使用 taskObj.Wait() 方法等待，或者 taskObj.IsCompleted 判断。<br style="box-sizing: border-box; outline: 0; margin: 0; padding: 0; overflow-wrap: break-word">3) Task<TResult>，表示异步方法将返回一个 Task<TResult> 对象，该对象的 Result 属性则是异步方法的执行结果，调用该属性时将阻塞当前线程（异步方法未执行完成时）。</p>
