What Hidden C# Features Can Boost My Programming Productivity?

Digging in the hidden characteristics of C#: The secret to improve efficiency

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.
