C#developers, ready to meet surprises! This article will reveal the hidden characteristics that are well -known but powerful in its ecosystem. Although the foundation and advanced concepts are widely known, this article will be discussed in depth that even experienced programmers may not be fully grasped.
The treasures of the excavated treasure
C# provides rich hidden characteristics, covering the following aspects:
Keywords
: Use this keyword to enhance the iterator function so that it can return multiple values.
: The encoding experience is simplified by allowing the compiler to easily infer the variable type.- : Using this statement to automatically release the object at the end of the scope, thereby improving the efficiency of resource management.
yield
: Enhance the data integrity by declaration by declaration. -
var
Features -
using()
- : Specify the default value for the attribute, simplify the initialization of the object.
readonly
: indicate that the specific elements have been abandoned, and guide developers to turn to update alternatives.
: The display method of the object in the custom debugger is used to improve the debugging efficiency. : The variables that retain their values in multiple threads are declared to achieve efficient thread local storage.
- grammar
DefaultValueAttribute
-
ObsoleteAttribute
(air merger) operator: By returning the default value by returning the default value by the calculation result of the expression to avoid . -
DebuggerDisplayAttribute
Digital logo: Use binary, decimal, hexadecimal, and octagonal logos to give additional information to digital. - : The generic type is limited to the type with a public non -parameter constructor.
ThreadStaticAttribute
Cisemodels: Simplify the generic method and class declaration by omitting type parameters.
Single parameter Lambda expression: When there is only one parameter, omit parentheses to express simple Lambda expressions. Automatic attributes: The declared attribute does not need to be explicitly supported by the field, thereby promoting a more concise encoding style.
- Naming space aliases: Use the abbreviated naming space name to simplify the code.
-
??
NullReferenceException
Language characteristics - Canadian type: Easily handle the empty value, allowing the deficiency of the value of the value without using the change method.
where T:new
Anonymous type: Create a lightweight data structure without explicit definition classes to enhance the readability and flexibility of the code. - Object initializer: Use simple grammar initialization objects, without repeated attribute assignment.
- Extension method: It can enhance its functions without modifying the existing type of source code.
- Visual Studio features
- Text block in the code editor: Quickly select the text block in the Visual Studio code editor to speed up editing and reconstruction tasks.
- Code fragment: Use built -in and custom code fragments to automate a common coding mode to save time and ensure consistency.
Framework
- : Use this powerful class to effectively operate the file path, support the combination path, retrieve the expansion name of the file, and check whether there are tasks such as the existence of the file.

System.IO.Path
Summary
This article only reveals a small part of the hidden characteristics of C#. Further exploring these features will improve your programming ability. Make good use of these hidden characteristics, improve your productivity, write more concise code, and easily and efficiently solve complex programming problems.

There are four commonly used XML libraries in C: TinyXML-2, PugiXML, Xerces-C, and RapidXML. 1.TinyXML-2 is suitable for environments with limited resources, lightweight but limited functions. 2. PugiXML is fast and supports XPath query, suitable for complex XML structures. 3.Xerces-C is powerful, supports DOM and SAX resolution, and is suitable for complex processing. 4. RapidXML focuses on performance and parses extremely fast, but does not support XPath queries.

C interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.

The main differences between C# and C are syntax, performance and application scenarios. 1) The C# syntax is more concise, supports garbage collection, and is suitable for .NET framework development. 2) C has higher performance and requires manual memory management, which is often used in system programming and game development.

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.

There are significant differences in the learning curves of C# and C and developer experience. 1) The learning curve of C# is relatively flat and is suitable for rapid development and enterprise-level applications. 2) The learning curve of C is steep and is suitable for high-performance and low-level control scenarios.

There are significant differences in how C# and C implement and features in object-oriented programming (OOP). 1) The class definition and syntax of C# are more concise and support advanced features such as LINQ. 2) C provides finer granular control, suitable for system programming and high performance needs. Both have their own advantages, and the choice should be based on the specific application scenario.

Converting from XML to C and performing data operations can be achieved through the following steps: 1) parsing XML files using tinyxml2 library, 2) mapping data into C's data structure, 3) using C standard library such as std::vector for data operations. Through these steps, data converted from XML can be processed and manipulated efficiently.

C# uses automatic garbage collection mechanism, while C uses manual memory management. 1. C#'s garbage collector automatically manages memory to reduce the risk of memory leakage, but may lead to performance degradation. 2.C provides flexible memory control, suitable for applications that require fine management, but should be handled with caution to avoid memory leakage.
