C#字符串轉枚舉

定義一個表示方向的枚舉：

public enum Position
{
    [Description("上")]
    Up,
    [Description("下")]
    Down,
    [Description("左")]
    Left,
    [Description("右")]
    Right
}

枚舉轉字符串：

string strPosition = Position.Left.ToString();

字符串轉枚舉：

Position position = (Position)Enum.Parse(typeof(Position), strPosition, true);
