使用async修饰符可将方法、lambda表达式或匿名方法指定为异步。如果对方法或表达式使用此修饰符,则其称为异步方法。如下示例定义了一个名为ExampleMethodAsync的异步方法: publicasyncTask<int>ExampleMethodAsync(){//...} 如果不熟悉异步编程,或者不了解异步方法如何在不阻止调用方线程的情况下使用await运算符执行可能...
A lambda object must not outlive any of its reference captured objects. EXP62-CPP Do not access the bits of an object representation that are not part of the object's value representation. EXP63-CPP Do not rely on the value of a moved-from object. INT50-CPP Do not cast to an...

下一个选项涉及使用 lambda 表达式。lambda 表达式定义了一个不属于任何类的方法。我们创建这样一个方法,调用另一个方法所需的参数,并在另一个线程中启动它。当我们启动threadThree线程时,它打印出 12 个数字,这些数字正是我们通过 lambda 表达式传递给它的数字。
