用dataview排序筛选很方便

private void MakeDataView() { DataView view = new DataView(); view.Table = DataSet1.Tables["Suppliers"]; view.AllowDelete = true; view.AllowEdit = true; view.AllowNew = true; view.RowFilter = "City = 'Berlin'"; view.RowStateFilter = DataViewRowState.ModifiedCurrent; view.Sort = "CompanyName DESC"; // Simple-bind to a TextBox control Text1.DataBindings.Add("Text", view, "CompanyName"); }
