C#字符串转枚举

定义一个表示方向的枚举：

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

枚举转字符串：

string strPosition = Position.Left.ToString();

字符串转枚举：

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