.Net多个DataTable合并，及过滤掉DataTable中重复数据行

DataTable dt01= new DataTable();
DataTable dt02= new DataTable();
DataTable dtRs = new DataTable();

dt01=sqlHelper.GetDataTable(strSQL001)
dt02=sqlHelper.GetDataTable(strSQL002)

//数据表dt02与dt01合并
dt01.Merge(dt02);

//多个表合并可能产生重复数据，过滤掉重复数据
DataView dv = new DataView(dt01);
dtRs = dv.ToTable(true, new[] { "ID", "WordName" });
