两种状态显示处理. enum , Linq AsEnumerable

1.ENUM

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    GridViewRow row = e.Row;
    if (e.Row.RowIndex < 0)
    {
        return;
    }
    string statusNum = row.Cells[5].Text;
    int tempStatusNum = int.Parse(statusNum);
    ShipStatus temp2 = (ShipStatus)tempStatusNum;
    row.Cells[5].Text = temp2.ToString();
} 

enum ShipStatus
{
    初始 = 0, 审核通过 = 1, 已发送 = 2
}

2. AsEnumerable 思路,先把所有状态 放到一张临时表,再进行连接.

     var dt = DataTableA
     var dtstatus = DtStatus();
            var res = from a in dt.AsEnumerable()
                      join s in DtStatus().AsEnumerable() on a["status"] equals s["statusEN"] into dtjoin
                      from dj in dtjoin.DefaultIfEmpty()
                      select new
                      {
                          orderCode = a["orderCode"],
                          status = dj["statusCN"]
                          //...................
                      };

            var dtres = Functions.EnumerableToDataTable(res);

            GVorderStatus.DataSource = dtres;

        public DataTable DtStatus()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("statusEN", typeof(System.String)));
            dt.Columns.Add(new DataColumn("statusCN", typeof(System.String)));

            dt.Rows.Add("WMS_ARRIVAL", "SS");
            dt.Rows.Add("WMS_RECEIVED", "AA");
            dt.Rows.Add("WMS_REJECT", "FF");
            dt.Rows.Add("WMS_FAILED", "HH");
             //.......................
            return dt;
        }
