Question

我跟着article将WCF服务包含到我的ASP.NET核心应用程序中。

似乎Generated Reference.cs文件自动包含异步操作。 是否可以仅使这些操作同步？在Reference.cs中使用它们在客户端。？

生成的Reference.cs文件如下所示 -

您可以同步调用异步方法，有几种方法可以执行此操作：

Task<T>使用：

var result = Task.Run(AsyncMethod).Result;  
// if the Task fails, GetResult() will just throw an `AggregateException`

// or use

var result AsyncMethod.GetAwaiter().GetResult();
// if the Task fails, GetResult() will just throw the exception caused directly

对于Task（不是Task<T>），请使用：

AsyncMethod.RunSynchronously();

如何在代理类中使用只作为同步的操作？
