How to use enumeration values? Summary of enumeration value instance usage

Jun 12, 2017 am 09:05 AM

This article mainly introduces the relevant information about C# getting the corresponding text description from the enumeration value. Friends who need it can refer to the C# getting the corresponding text description from the enumeration value. Sometimes when the enumeration value is displayed, it needs to Displays the text string corresponding to the enumeration value. One solution is to use switch or if to judge the enumeration value at the place of call, and then assign it to different text strings, but this will be more troublesome if it is used in many places. Of course, some people say that in this case, you can encapsulate a method for this enumeration value and then call it. What if there are multiple enumeration types that have such a requirement? Is there any more general solution? some. You need to use the Description attribute here, assign this attribute to each enumeration value, and then assign the text string to be described in this attribute. For example #region YesNoEnum public enum YesNoEnum { [Description(&

How to use enumeration values? Summary of enumeration value instance usage

Introduction : Adding a new value to a list is a common and necessary requirement. Schema designers often want to build a way to add additional value to the system architecture, and how this additional value is created is unknown to the schema designer during the design phase. An extensible, easy-to-implement enumeration value list? This article will introduce several methods to achieve this goal. Pattern designers and implementers need an extension

MySQL LIST partition

How to use enumeration values? Summary of enumeration value instance usage##Introduction: LIST partition and RANGE partitioning is very similar. The main difference is that LIST is a collection of enumerated value lists, and RANGE is a collection of continuous interval values. The syntax of the two is very similar. It is also recommended that the LIST partitioning column be a non-null column, otherwise a null value will be inserted. If there is no null value in the enumeration list, the insertion will fail. This is different from other partitions. The RANGE partition will store it as the minimum partition value. HASH\KEY will convert it into 0 for storage. The main LIST partition only supports it. Integer and non-integer fields need to be converted into integer through functions; after version 5.5, function conversion is not required and the LIST COLUMN partition is used to support non-integer fields. In the COLUMN partition

Introduction: The enumeration in PropertyGrid is displayed in Chinese. In system development, PropertyGrid is often used to modify or display the properties of an object. , if an enumeration is defined in the class, the enumeration items or enumeration values ​​will be displayed by default, but this is not what we want. The user does not know what the item represents when using it. The enumeration shows

How to use various symbols in C language How to use various symbols in C language Apr 03, 2025 pm 04:48 PM

The usage methods of symbols in C language cover arithmetic, assignment, conditions, logic, bit operators, etc. Arithmetic operators are used for basic mathematical operations, assignment operators are used for assignment and addition, subtraction, multiplication and division assignment, condition operators are used for different operations according to conditions, logical operators are used for logical operations, bit operators are used for bit-level operations, and special constants are used to represent null pointers, end-of-file markers, and non-numeric values.

What is the role of char in C strings What is the role of char in C strings Apr 03, 2025 pm 03:15 PM

In C, the char type is used in strings: 1. Store a single character; 2. Use an array to represent a string and end with a null terminator; 3. Operate through a string operation function; 4. Read or output a string from the keyboard.

How to handle special characters in C language How to handle special characters in C language Apr 03, 2025 pm 03:18 PM

In C language, special characters are processed through escape sequences, such as: \n represents line breaks. \t means tab character. Use escape sequences or character constants to represent special characters, such as char c = '\n'. Note that the backslash needs to be escaped twice. Different platforms and compilers may have different escape sequences, please consult the documentation.

The difference between multithreading and asynchronous c# The difference between multithreading and asynchronous c# Apr 03, 2025 pm 02:57 PM

The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.

The difference between char and wchar_t in C language The difference between char and wchar_t in C language Apr 03, 2025 pm 03:09 PM

In C language, the main difference between char and wchar_t is character encoding: char uses ASCII or extends ASCII, wchar_t uses Unicode; char takes up 1-2 bytes, wchar_t takes up 2-4 bytes; char is suitable for English text, wchar_t is suitable for multilingual text; char is widely supported, wchar_t depends on whether the compiler and operating system support Unicode; char is limited in character range, wchar_t has a larger character range, and special functions are used for arithmetic operations.

How to convert char in C language How to convert char in C language Apr 03, 2025 pm 03:21 PM

In C language, char type conversion can be directly converted to another type by: casting: using casting characters. Automatic type conversion: When one type of data can accommodate another type of value, the compiler automatically converts it.

What is the difference between char and unsigned char What is the difference between char and unsigned char Apr 03, 2025 pm 03:36 PM

char and unsigned char are two data types that store character data. The main difference is the way to deal with negative and positive numbers: value range: char signed (-128 to 127), and unsigned char unsigned (0 to 255). Negative number processing: char can store negative numbers, unsigned char cannot. Bit mode: char The highest bit represents the symbol, unsigned char Unsigned bit. Arithmetic operations: char and unsigned char are signed and unsigned types, and their arithmetic operations are different. Compatibility: char and unsigned char

How to use char array in C language How to use char array in C language Apr 03, 2025 pm 03:24 PM

The char array stores character sequences in C language and is declared as char array_name[size]. The access element is passed through the subscript operator, and the element ends with the null terminator '\0', which represents the end point of the string. The C language provides a variety of string manipulation functions, such as strlen(), strcpy(), strcat() and strcmp().
