The mutex has a reentrant, non-reentrant score. In the C + + standard library, a mutex is used to represent a non-reentrant mutex, and a recursive_mutex is used to represent a reentrant mutex. For these two classes to increase the ability to block

The Expression-bodied method is another feature in C # 6.0 that simplifies code. We are already familiar with the use of lambda expressions to correlate Funciton and delegation. Expression-bodied extends this use of lambda expressions to methods.As
It is often necessary to format strings in the development process. We generally use the String.Format () method, which replaces each format item in the specified string with the text equivalent of the value of the corresponding object. Although
