DataView与DataTable之间互用

 

DataView dv = new DataView(dt);//把DataTable转换为DataView

 

DataTable dtDistinct = dv.ToTable(true, new string[] { "f_majorname" }); //取该表中以

 

f_majorname字段为准的非重复的(去掉DataTable中的重复项)

 

 

dv.RowFilter = "f_majorname='" + strname[k].ToString() + "'"; //从DataView中筛选数据

 

dv.ToTable() //视图转化为DataTable
