C#读取Enum内容

Enum放入类中和方法同级别。

示例一：

enum WeekDay
{ 
   Sun=1,
   Mon=2,
   Tue=3,
   Wed=4,
   Thi=5,
   Fri=6,
   Sat=7
}

读取：

foreach (WeekDay c in (WeekDay [])Enum.GetValues(typeof(WeekDay )))
{
Console.Write(String.Format("{0}是一周第{1}天"，c.ToString()，（int）c));
}

 

示例二：

Ajax方法获取：

/// <summary>
/// 获取订单状态列表
/// </summary>
/// <param name="context"></param>
/// <returns></returns>
private string GetSaleOrderBillStatusList(HttpContext context)
{
    ArrayList array = new ArrayList();
    SortedList list = AppEnum.GetStatus(typeof(AppEnum.SaleOrderBillStatus));
    array.Add(list);
    return XX.Common.SystemUtility.SerializeObject(array);
}

返回的json字符串如下：

[{"1":"未付款","2":"等待发货","3":"已发货","4":"交易成功"}]
