Enum 枚举

一：

1.

foreach (int val in Enum.GetValues(typeof(AppEnum.HarbourStatus)))

{



          ddlStatus.Items.Add(new ListItem(Enum.GetName(typeof(AppEnum.HarbourStatus), val), val.ToString()));



}



ddlStatus.Items.FindByText(AppEnum.HarbourStatus.Avtal.ToString()).Selected = true;



2.

public enum HarbourStatus

{

            Ansökan = 1,

            Avtal = 2,

            Makulerad = 3,

            Köplats = 4

}

　　

二：

        [DisplayString("Response Error")]

        ResponseError = -003, //error when get response



        NoResponse = -004, // no response need to be checked

        ResponseOk=0, //

    }
