public static List<T> GetColumnValues<T>(DataTable dtSource,string filedName)

return (from r in dtSource.AsEnumerable() select r.Field<T>("ID")).ToList<T>();
}
方法调用:
获取字段ID的所有值
DataTable dt = ......;
List<int> ids= DataTablePro.GetColumnValues<int>(dt, "ID");
直接使用:
//遍历DataTable,取出所有的ID :
List<int> lstID = (from d in dt.AsEnumerable() select d.Field<int>("ID")).ToList();
