You can convert an int value to an enumeration (enum) type using type casting or the Enum.Parse method.
Here's how you can do it:

Type Casting

You can directly cast an int to the enum type if the integer value corresponds to one of the defined enum values.

enum MyEnum {
    Value1,
    Value2,
    Value3
}

class Program {
    static void Main(string[] args) {
        int intValue = 2;
        MyEnum enumValue = (MyEnum)intValue;
        Console.WriteLine(enumValue); // Output: Value3
    }
}

Enum.Parse Method

If you need to convert an int value to an enum and you're not sure if the integer value corresponds to a valid enum value, you can use the Enum.Parse method.

enum MyEnum {
    Value1,
    Value2,
    Value3
}

class Program {
    static void Main(string[] args) {
        int intValue = 2;
        MyEnum enumValue = (MyEnum)Enum.Parse(typeof(MyEnum), intValue.ToString());
        Console.WriteLine(enumValue); // Output: Value3
    }
}

Convert.ChangeType Method

You can also use the Convert.ChangeType method if you prefer.

enum MyEnum {
    Value1,
    Value2,
    Value3
}

class Program {
    static void Main(string[] args) {
        int intValue = 2;
        MyEnum enumValue = (MyEnum)Convert.ChangeType(intValue, typeof(MyEnum));
        Console.WriteLine(enumValue); // Output: Value3
    }
}
