When to Use Enum in C Enums in C are used to define a set of named integral constants that represent a set of related values. Here are some situations where enums are commonly used: Improving Code Readability:
You have the flexibility to assign custom values to the elements within an enum. By default, the first member of an enum is assigned a value of zero. However, if this value is not appropriate for your specific enum, you have the option to assign it a different value, such as one or ...
String-based enums, just like object literals, support computed names with the use of the square bracket notation, and this is usually not the case for number-based enums. Therefore, this limits our ability to use number-based enums in JSON objects, as it is usually not possible to compu...
whichvalues()returns. For each value, theswitchstatement (enhanced to support typesafe enums) chooses thecasethat corresponds to the value ofdand outputs an appropriate message. (You don’t prefix an enum constant, e.g.,NORTH, with its enum type.) Lastly, Listing 1 evaluatesDirection.NORTH.c...
Structures inherit fromValueType, which in turn is derived fromObject. AlthoughValueTypeoverridesObject.ToString, its implementation is identical. Override the ToString method Displaying the name of a type is often of limited use and does not allow consumers of your types to differentiate one instance...
We can also use the inbuilt methodsType.GetEnumValues()orType.GetEnumNames()to get the same result: Type dayOfWeekEnum =typeof(DayOfWeek); varvalues = dayOfWeekEnum.GetEnumValues(); foreach(varvalueinvalues) { Console.WriteLine(value); ...
The below code uses enum and the value to evaluate is hard coded. If I wanted to take user input from console and store in a string, how would i then use this string value to compare with the enum values?Copy switch (Party.Conservative) { case Party.Labour: Console.WriteLine("You ...
Please see the model, enum and controller class below for your reference , if this is not the best approach, can you please suggest other best approach which can be used for a enterprise Api Thanks in Advance and good weekend. 复制 [HttpPost] public IActionResult Calculate(PolicyHolder pol...
In the example, we create an enum inside theSwitchEnumclass and name itDays. It holds seven constants that are the days of a week. We use the switch and case method to show a different message for each day. We get the value from the enum using the constant’s name likeDays.MONDAYwil...
DeviceInfoSet = SetupDiGetClassDevs(ClassesToClean[i], NULL, NULL, 0 ); if (INVALID_HANDLE_VALUE!=DeviceInfoSet) { DeviceInfoData.cbSize = sizeof(DeviceInfoData); MemberIndex = 0; while (SetupDiEnumDeviceInfo(DeviceInfoSet, MemberIndex++, ...
