Linq 学习之一 （Linq与DataTable）

将一个dataTABLE转化成linq：

 1 DataTable dtChangeDetail = new DataTable();
 2                     dtChangeDetail.Columns.Add("IsModi",typeof(Boolean));               //记录是否变动
 3                     dtChangeDetail.Columns.Add("FromDeptID", typeof(Int32));
 4                     dtChangeDetail.Columns.Add("FromPostID", typeof(String));
 5                     dtChangeDetail.Columns.Add("FromPostNumBef",typeof(Int32));
 6                     dtChangeDetail.Columns.Add("FromPostNumChange", typeof(Int32));
 7
 8 var data = from row in dtChangeDetail.AsEnumerable()
 9                                select new
10                                {
11                                    IsModi = false,
12                                    FromDeptID = row.Field<Int32>("FromDeptID"),
13                                    FromPostID = row.Field<string>("FromPostID"),
14                                    FromPostNumBef = row.Field<Int32>("FromPostNumBef")                                  };    List a = data.ToList();
