C# Linq Where 사용법(DataTable)

DataTable을 사용한 Linq Where절 사용방법 입니다.

//검색조건
String _SelectValue = "P01";
 
//Linq Where절
var query =
from order in _dtSource.AsEnumerable()
where order.Field<string>("PBOXID") == _SelectValue 
select new
{
    BAR_CD = order.Field<String>("BAR_CD"),
    ITEM_NM = order.Field<String>("ITEM_NM"),
    CNT = order.Field<String>("CNT"),
    CREATE_DT = order.Field<String>("CREATE_DT")
};
 
//그리에 DataSource 
RGrid.DataSource = query.ToArray();
