You may need to run an async method synchronously due to being hosted in a method that is not marked as async. Try calling like this:#!csharpvar dotNet = GetAsync("https://dot.net") .GetAwaiter().GetResult(); display($"DotNet HTML length: {dotNet.Length}");...
第五章,“使用 C# 5.0”,详细解释了新的 C# 5.0 特性 - 异步方法。您将了解 async 和 await 关键字的含义,以及如何在不同场景中使用它们,以及 await 在幕后的工作原理。 第六章,“使用并发集合”,描述了.NET Framework 中包含的用于并行算法的标准数据结构。它涵盖了每种数据结构的示例编程场景。 第七章,“...
An async method runs synchronously until it reaches its firstawaitexpression, at which point the method is suspended until the awaited task is complete. In the meantime, control returns to the caller of the method, as the example in the next section shows. ...
Connect("sample_keyspace"); // Execute a query on a connection synchronously var rs = session.Execute("SELECT * FROM sample_table"); // Iterate through the RowSet foreach (var row in rs) { var value = row.GetValue<int>("sample_int_column"); // Do something with the value }...
Can i use TolistAsync() when doing LINQ to object Can lock work between multiple objects of a class ? Can multiple threads safely run the same method simultaneously? can not cast interface to object which imlements it Can not find System.Web in add reference. Can not implicitly convert '...
method is frequently expected to return synchronously, and where it’s unlikely we can cache a completed task for all common return values. For instance, the runtime can cache a completed Task<bool> for a result of true and one for a result of false, but it can’t cache fo...

When the await completes, it attempts to execute the remainder of the async method within the captured context. But that context already has a thread in it, which is (synchronously) waiting for the async method to complete. They’re each waiting for the other, causing a deadlock. To Do ...
