C#dataTable實現快速篩選

this.dataTable.DefaultWiev.RowFilter=string.Format("ClassName='{0}'",this.cboClass.Text.Trim();
//篩選字符串

if(!Common.DataValidate.IsInteger(this.score.Text.Trim())) return;//判斷是否爲整數
this.dataTable.DefaultView.RowFilter=string.Format("Score>{0}",this.score.Text.Trim());
//篩選數字

this.dataTable.DefaultView.RowFilter="ClassName like'%%'";
//顯示全部
