Priority of operators in C#: unary operator () (positive sign), - (negative sign), ! (logical NOT), ~ (bitwise NOT) * (multiplication), / (division) ), % (remainder) (addition), - (subtraction) (greater than), >= (greater than or equal to), == (equal to) , != (not equal) && (logical AND), || (logical OR), ^ (logical exclusive OR)?:: (condition? true_expression : false_expression)= (assignment), =, -=, *=, / = (compound assignment)
The precedence of operators in C
#In C#, the precedence of operators The level determines the order in which expressions are evaluated. The precedence of operators from high to low is:
Unary operator
-
()
: Parentheses -
-
-
: Negative sign -
!
: Logical negation -
~
: Bitwise notation
Multiplication and division operators
-
*
: Multiplication -
/
: Division -
%
: Remainder
Addition and subtraction operators
-
-
-
: Subtraction
Comparison operator
- ##: less than
- : less than or equal to
- >
: greater than
- >=
: greater than or equal to
- ==
: equal to
- !=
: Not equal to
Logical operator
- ##&&
- : Logical AND
- : Logical OR
- : Logical XOR
- ?:
- : Condition? true_expression : false_expression
- =
- : Assignment
- ,
-=
,*=
,/=
: Compound assignment
The following example illustrates how operator precedence affects the evaluation of an expression:
int x = 1 + 2 * 3; // 7 int y = (1 + 2) * 3; // 9
In the first expression, multiplication operator has higher precedence than the addition operator, so the expression first evaluates
2 * 3 before adding the result to 1
. In the second expression, the parentheses have higher precedence than the multiplication operator, so the expression first evaluates
and then compares the result with 3
Multiply.
The above is the detailed content of Operator precedence in c#. For more information, please follow other related articles on the PHP Chinese website!

C# and .NET are suitable for web, desktop and mobile development. 1) In web development, ASP.NETCore supports cross-platform development. 2) Desktop development uses WPF and WinForms, which are suitable for different needs. 3) Mobile development realizes cross-platform applications through Xamarin.

The C#.NET ecosystem provides rich frameworks and libraries to help developers build applications efficiently. 1.ASP.NETCore is used to build high-performance web applications, 2.EntityFrameworkCore is used for database operations. By understanding the use and best practices of these tools, developers can improve the quality and performance of their applications.

How to deploy a C# .NET app to Azure or AWS? The answer is to use AzureAppService and AWSElasticBeanstalk. 1. On Azure, automate deployment using AzureAppService and AzurePipelines. 2. On AWS, use Amazon ElasticBeanstalk and AWSLambda to implement deployment and serverless compute.

The combination of C# and .NET provides developers with a powerful programming environment. 1) C# supports polymorphism and asynchronous programming, 2) .NET provides cross-platform capabilities and concurrent processing mechanisms, which makes them widely used in desktop, web and mobile application development.

.NETFramework is a software framework, and C# is a programming language. 1..NETFramework provides libraries and services, supporting desktop, web and mobile application development. 2.C# is designed for .NETFramework and supports modern programming functions. 3..NETFramework manages code execution through CLR, and the C# code is compiled into IL and runs by CLR. 4. Use .NETFramework to quickly develop applications, and C# provides advanced functions such as LINQ. 5. Common errors include type conversion and asynchronous programming deadlocks. VisualStudio tools are required for debugging.

C# is a modern, object-oriented programming language developed by Microsoft, and .NET is a development framework provided by Microsoft. C# combines the performance of C and the simplicity of Java, and is suitable for building various applications. The .NET framework supports multiple languages, provides garbage collection mechanisms, and simplifies memory management.

C# and .NET runtime work closely together to empower developers to efficient, powerful and cross-platform development capabilities. 1) C# is a type-safe and object-oriented programming language designed to integrate seamlessly with the .NET framework. 2) The .NET runtime manages the execution of C# code, provides garbage collection, type safety and other services, and ensures efficient and cross-platform operation.

To start C#.NET development, you need to: 1. Understand the basic knowledge of C# and the core concepts of the .NET framework; 2. Master the basic concepts of variables, data types, control structures, functions and classes; 3. Learn advanced features of C#, such as LINQ and asynchronous programming; 4. Be familiar with debugging techniques and performance optimization methods for common errors. With these steps, you can gradually penetrate the world of C#.NET and write efficient applications.
