一、重生法
dstaset.Tables.Add(dt)
dataset.Tables(0).DefaultView.Sort = "id desc"
--------------------------------------------------------------------------------
二、直接法
dv = New DataView(dt)
dv.Sort = "id desc"
--------------------------------------------------------------------------------
三、间接法
dv = New DataView(ds.Tables[0])
dv.Sort = "id desc"
DataRow[] rows = dataTable1.Select("", "ord asc");
DataTable t = DataTable1.Clone();
t.Clear();
foreach (DataRow row in rows)
t.ImportRow(row);
DataTable1 = t;
VS2005中这种方法最简单:
DataView dv = dt.DefaultView;
dv.Sort = "c1 Asc";
DataTable dt2 = dv.ToTable();
----
//拿到数据源
DataView dv = this.dtDataSource.Copy().DefaultView;
//排序
dv.Sort = "Columns1 asc,Columns2 asc,Columns3 asc";
//过滤重复数据
//DataTable dt = dv.ToTable(true, "Columns1", "Columns2", "Columns3");
//不过滤重复数据
DataTable dt = dv.Table.Copy();
