One, the Task Parallel libraryThe Task Parellel Library is a class library in the BCL that greatly simplifies parallel programming, with Parallel.For and Parallel.ForEach as an example. It is common in C # to use For/foreach loops, and if iterations

1. What is asynchronousIf a program calls a method and waits for it to perform all processing before proceeding, we call this method synchronous.If a program calls a method and returns to the calling method before the method finishes processing, the

Remember:A base class with polymorphic properties should declare a virtual destructor. If class has any virtual functions, it should have a virtual destructor.The design purpose of class is not to declare a virtual destructor if it is not used as a

Reflection describes the ability to inspect and process program elements while they are running. Reflection can accomplish the following tasks: The members of the enumeration type; Instantiate a new object; The members of the

In the AOP programming concept, a common example is intercepting an object and logging the log before and after a method of the object executes.The most common way to intercept is to use the dynamic proxy class, which encapsulates a log interceptor
