Thread is a single sequential control process in a process. A thread is an entity in a process. A process can have multiple threads, and a thread must have a parent process.Threads generally have three basic states of read,blocking and operation.

Factory method Mode (Factory): Defines an interface for a feudal object, which allows subclasses to think Shiwa which class, the factory method, defers the instantiation of a class to its subclasses.Simple Factory Model Advantages: The factory class

Prototype mode (PROTOTYPE): Specifies the kind of object created with the prototype instance, and creates a new object by copying the prototypes. The prototype pattern is actually creating another customizable object from one object without needing

The function wrapper wraps up the function: it has the following characteristics1. Design a common function execution interface, you can set the count (number of function executions) and level2. Function wrappers rely on function templates to

C # supports executing code in parallel through multithreading, where a thread has its own execution path and can run concurrently with other threads. A C # program starts with a single thread, which is created automatically by the CLR and the

Multithreading, as the name implies, is the implementation of multiple tasks in an application, in C #, thread threads is included in the System.Threading namespace.One, the simplest way to create a threads is to create a threads instanceegThread

Proxy mode: Provides a proxy for other objects to control access to this object.Scenario: 1. A remote proxy, which provides a local representation of an object in a different address space, can hide the fact that an object exists in a different

The Break keyword function : 1, jump out of switch-case structure.2. Jump out of the current loop.Break is generally not used alone, but is used with the If judgment, indicating that when certain conditions are met, it is no longer

In this C # class, the teacher told us the 22nd chapter of the data flow related content. First we need to use the class in the System.IO namespace. These classes include the file class that represents one of the files on the disk, and the directory
