There are numerous ways to do this, but if you want a simple example, this will do. It just needs to be enhanced with necessary defensive coding to check for type safety and invalid parsing, etc.

    /// 

    /// Extension method to return an enum value of type T for the given string.
    /// 
    /// 
    /// 
    /// 
    public static T ToEnum(this string value)
    {
        return (T) Enum.Parse(typeof(T), value, true);
    }

    /// 

    /// Extension method to return an enum value of type T for the given int.
    /// 
    /// 
    /// 
    /// 
    public static T ToEnum(this int value)
    {
        var name = Enum.GetName(typeof(T), value);
        return name.ToEnum();
    }
