如何從C＃中的數據庫中取出數據＃

Question

有狀態表，它有狀態名和循環，但它們沒有在表中排序。 我使用OrderByAsc("StateName")其中StateName是狀態表的列名。我如何在下拉列表中獲得排序狀態。我使用亞音速從數據庫獲取數據。

StateCollection stc = (new 
StateController()).getInstance().WFetchAll(true); 


    ddlState.Items.Clear(); 
    if(addAllStates) 
     ddlState.Items.Add(new ListItem("All States", "0")); 

    //ddlState.DataSource = State.FetchAll(); 
    //ddlState.DataTextField = State.Columns.StateName; 
    //ddlState.DataValueField = State.Columns.CircleCode; 
    //ddlState.DataBind(); 
    stc = stc.OrderByAsc("CircleCode"); 
    stc.SaveAll(); 
    foreach (State st in stc) 
    { 
     ddlState.Items.Add(new ListItem(st.CircleCode + "-" + st.StateName, st.CircleCode)); 
    } 

Answer 1

嘗試

foreach (State st in stc.OrderBy(s => s.StateName)) 
{ 
    ddlState.Items.Add(new ListItem(st.CircleCode + "-" + st.StateName, st.CircleCode)); 
}
