You could use following method to do that:

public static Output GetEnumItem(Input input)
    {
        //Output type checking...
        if (typeof(Output).BaseType != typeof(Enum))
            throw new Exception("Exception message...");

        //Input type checking: string type
        if (typeof(Input) == typeof(string))
            return (Output)Enum.Parse(typeof(Output), (dynamic)input);

        //Input type checking: Integer type
        if (typeof(Input) == typeof(Int16) ||
            typeof(Input) == typeof(Int32) ||
            typeof(Input) == typeof(Int64))

            return (Output)(dynamic)input;

        throw new Exception("Exception message...");
    }

Note:this method only is a sample and you can improve it.
