C#dataTable实现快速筛选

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

if(!Common.DataValidate.IsInteger(this.score.Text.Trim())) return;//判断是否为整数
this.dataTable.DefaultView.RowFilter=string.Format("Score>{0}",this.score.Text.Trim());
//筛选数字

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