In the given example, we are creating an enumAccountStatus. In our application, we can denote an account’s status with any of the multiple values. For instance, we can indicate an active status with the strings “A“, “active" and even aninteger value1. Similarly, other statuses can h...
Converts the specified 32-bit signed integer to an enumeration member. ToObject(Type, Int64) Converts the specified 64-bit signed integer to an enumeration member. ToObject(Type, Object) Converts the specified object with an integer value to an enumeration member. ToObject(Type, SByte) ...
numValue StringValue IntegerValue --- --- --- White White 0 Grey Grey 1 Grey Grey 1 Black Black 2 枚举值同义词 可以定义为同一整数值提供不同名称的枚举。 执行此操作时,指向相同基础值的名称称为同义词。 使用同义词的枚举使用户能够为同一值指定不同的名称。 使用同义词定义枚举时,不要编写依赖于...
Compares this enum with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. Enum constants are only comparable to other enum constants of the same enum type. The natural order ...

Byte 2 An 8-bit unsigned integer ranging in value from 0 to 255. Boolean 3 A simple type representing Boolean values of true or false. Currency 4 A currency value ranging from -2 63 (or -922,337,203,685,477.5808) to 2 63 -1 (or +922,337,203,685,477.5807) with an accuracy to ...
When annotating @JsonValue on the int/Integer value, the enum can be serialized as number successfully. when i deserializing it by using a number JSON string, it will throw exception. But it work well when using a 'String' type JSON stri...
To take it one step further, you can also find the associated integer values of the enumeration. This can be useful in certain programming scenarios.Here is a one-liner to accomplish that. All we do is cast the enumeration value to int and print it to the screen along wit...
To create an enum, use the enum keyword (instead of class or interface), and separate the enum items with a comma:ExampleGet your own C# Server enum Level { Low, Medium, High } You can access enum items with the dot syntax: Level myVar = Level.Medium; Console.WriteLine(myVar); Try...
