How to calculate the total number of items defined in an enum in C#, How to get Enum string name from int value in C#, How to get the typecode for enum in C#, How to get the hashcode for enum in C#

Get name, typecode, hashcode from Enum in C#

To calculate the total number of items defined in an enum in C#, you can use the Enum.GetNames method to get an array of all the enum names and then use the Length property of that array to get the total count:

int totalItems = Enum.GetNames(typeof(MyEnum)).Length;

To get the Enum string name from an int value in C#, you can use the Enum.GetName method:

int value = 1; string name = Enum.GetName(typeof(MyEnum), value);

To get the typecode for an enum in C#, you can use the Type.GetTypeCode method:

TypeCode typeCode = Type.GetTypeCode(typeof(MyEnum));

To get the hashcode for an enum in C#, you can simply call the GetHashCode method on the enum value:

MyEnum value = MyEnum.SomeValue; int hashCode = value.GetHashCode();

Examples

  1. C# get enum name: Getting the name of an enum in C#.

    DaysOfWeek day = DaysOfWeek.Monday; string enumName = Enum.GetName(typeof(DaysOfWeek), day);

  2. Retrieve type code of enum in C#: Retrieving the underlying type code of an enum in C#.

    TypeCode typeCode = Type.GetTypeCode(typeof(DaysOfWeek));

  3. Get hash code of enum in C#: Getting the hash code of an enum in C#.

    DaysOfWeek day = DaysOfWeek.Monday; int hashCode = day.GetHashCode();

  4. Enum.GetName method in C#: Using Enum.GetName to retrieve the name of an enum.

    DaysOfWeek day = DaysOfWeek.Monday; string enumName = Enum.GetName(typeof(DaysOfWeek), day);

  5. Getting enum name and value pairs in C#: Getting name and value pairs of an enum in C#.

    var enumPairs = Enum.GetValues(typeof(DaysOfWeek)).Cast<DaysOfWeek>() .Select(e => new { Name = e.ToString(), Value = (int)e });

  6. C# enum type code example: Retrieving the underlying type code of an enum in C#.

    TypeCode typeCode = Type.GetTypeCode(typeof(DaysOfWeek));

  7. Calculating hash code for enum values in C#: Calculating hash codes for enum values in C#.

    int hashCode = DaysOfWeek.Monday.GetHashCode();

  8. Using Reflection to get enum information in C#: Using Reflection to retrieve information about an enum.

    Type enumType = typeof(DaysOfWeek); var enumValues = Enum.GetValues(enumType); var enumNames = Enum.GetNames(enumType);

  9. Accessing enum members and their properties in C#: Accessing properties of enum members in C#.

    public enum Colors { [Description("Red color")] Red, [Description("Green color")] Green, [Description("Blue color")] Blue } var redDescription = GetEnumDescription(Colors.Red); // ... private static string GetEnumDescription(Enum value) { FieldInfo field = value.GetType().GetField(value.ToString()); DescriptionAttribute attribute = (DescriptionAttribute)Attribute.GetCustomAttribute(field, typeof(DescriptionAttribute)); return attribute != null ? attribute.Description : value.ToString(); }

  10. GetHashCode method for enum in C#: Getting the hash code of an enum using the GetHashCode method.

    DaysOfWeek day = DaysOfWeek.Monday; int hashCode = day.GetHashCode();
