In addition, press CTRL+L

The simple understanding is that the CLR is the chef that makes the CLI this recipe play its real role.Let's try these dishes:Food : Class Library (Framework class LIBRARY,FCL), all in. NET can use the class library. Divided into two parts, part of the raw material , the other part of the finished dish .
Raw Materials : The base Class library (BCL) , as its name implies, contains some basic classes, such as: Io,string,net, and so on. They are the ingredien
I. GENERAL descriptionThese three words appear in the Python class, and the self and the CLS can be replaced by other words, and there are three methods of the class.One is defined by Def, the ordinary general, need to pass at least one parameter, generally with self, such a method must be accessed through an instance of a class, similar to C + + through the object to access;The second is to add @classmethod in front of Def, this kind of method is a f
First, let's simply look at what is called the CLS.
In view of the personal English level, I will give the CLS the English explanation first, then I translate again:
The CLS is a specification which defines the rules to support language integration. This is doing in such a way, which programs written in any language (. NET compliant) can interoperate with one a
CLR: The common language runtime is the common runtime environment for programs written by all. NET languages, such as C # and VB. NET and other languages write programs that need to run on the CLR, and then the CLR resolves the instructions that execute the operating system, and the CLR is a required environment for the. NET program to run in the operating system.Just as a Java program must run in a Java virtual machine. Only the CLR runs all of the. NET supported language development programs,
CTS: common type system, general type system
CLS: Common Language specifiction Common Language Specification
CLR: Common Language Runtime
CTS refers to the rule that defines the Runtime Library of Public languages and plays an integrated role to achieve compatibility of different languages.
CLS refers to defining many verification rules to ensure that. Net compilers generateCodeCompatible with CLR.

Definition by DEFIt is necessary to pass at least one argument, self, so that the defined method must be accessed through an instance of a class, similar to the one accessed through an object in C + +;Two. ClassmethodThe characteristic of this class method is that it can be called by the class name, but a parameter must also be passed: The CLS, or class, that can be called directly by the class name;Three StaticmethodStatic class method, similar to
1. Self, CLS is not a keyword
In Python, self, the CLS is not a keyword, and you can use any variable you write in place of the same effect
Code 1
Copy Code code as follows:
Class MyTest:
myname = ' Peter '
def sayhello (hello):
Print "Say hello to%s"% Hello.myname
if __name__ = = "__main__":
MyTest (). SayHello ()
In code 1, you replace self with Hello, and you get the
CLS files are latex2e format files that determine the layout of the Latex source files. The most general CLS file is our usual article.cls, which is expressed in/documentclass{article}This sentence inside. If the Publisher provides a CLS file, we can use the following two methods (if the CLS file is named Xxx.cls):1)
high-level languages defined within the specification, and to run software on different computer architectures without modification. The CLI is an open technical specification that was launched by Microsoft, Hewlett-Packard, and Intel in 2000 to the ECMA initiative. To be blunt, the CLI is a set of specifications, and the CLR is an implementation of the CLI. So what exactly is defined in this specification of the CLI? You may wish to visit the ECMA website next, or download it here:As shown abo
During the written examination, the chinese meanings of CTS, CLS, and CLR are often obtained. Below is a brief description:
1. CTS
Common Type SystemA common type system is a model that defines the rules that a Common Language Runtime Library follows when declaring, using, and managing types. A framework is built for a general type system, which enables cross-language integration, type security, and high performance.
CodeExecution becomes possible.
The primary role of the CLR is to locate, load, and manage. NET objects on your behalf.The main role of the CLR is to locate, load, and manage for you. NET object.The CLR also takes care of a number of low-level details such as memory management, application hosting, coordinating thre Ads, and performing security checks (among other low-level details).The CLR focuses on some low-level details, including memory management, application hosting, process synchronization, and performing security chec
CLR -- Common Language Runtime FCL -- framework class library CTS -- common type system general type system CLS -- Common Language Specification general language specification (CER) -- Common intermediate language general intermediate language, the IL assembly language CLR/CTS is the most characteristic, and the cel assembly language can be used to implement all types of CTS. The access to all the characteristics of clr cts is the least characteristic
D: \ test> CLS /? Clear the screen. Clsd: \ test> ver /? Displays the Windows version. Verd: \ test> date /? Display or set a date. Date [/T | date] displays the current date settings and prompts for entering a new date. Enter a date without parameters. To retain the existing date, press Enter. If the command extension is enabled, the date command supports the/T switch. This switch indicates that the command only outputs the current date, but does not
programmed on the platform, the compiler will eventually compile it into a unifiedIlCode (for example, console output command in the example ). The above example shows thatCLRHow to support multi-language integration only requires different compilers to compile source filesCLROfIlCode, you can. NetRun under the framework.

· CLS is a subset of CTS, which defines the minimum specification required for the language of the program to be written on the. NET platform. Because. Net allows programs written in different languages to run together, CLS specifications are develope

However, portrait complexion is sallow (not only white balance problem, but also color tendency and brightness), emerald green is yellow, red is saturated and loses level.Among them, portrait photography is particularly troubling.
