asp中select 语句 初学者

一般情况下select语句都能被if 语句代替,但是if语句要比select语句执行效率差很多

能写select尽量写select

select case fenlei
case "xiaoxue"
     fenlei1 = "小学"
  txtstr = replacestr(txtstr,"xuanzhong","#小学#")
case "zhongxue"
     fenlei1 = "中学"
  txtstr = replacestr(txtstr,"xuanzhong","#中学#")
case "daxue"
     fenlei1 = "大学"
  txtstr = replacestr(txtstr,"xuanzhong","#大学#")
case "zhuanjia" 
     fenlei1 = "专家"
  txtstr = replacestr(txtstr,"xuanzhong","#专家#")
case "zhijiao"
     fenlei1 = "职教"
  txtstr = replacestr(txtstr,"xuanzhong","#职教#")
case "jiangshi"
     fenlei1 = "讲师"
  txtstr = replacestr(txtstr,"xuanzhong","#讲师#")
end select
