在当前目录下有数据库文件xsdak，数据库中有表文件stu．dbf，执行如下SQL语句后的结果是（）。　　 SELECT * FORM student INTO DBF xsdak ORDER BY 学号

A． List1．ListCount

B． List1．List(ListCount-1)

C． List1．ListIndex

D． List1．List(List．ListIndex)

答案

参考答案：D

解析：题中涉及到列表框的四个属性：Text属性、List属性、ListCount属性和listIndex属性，其中List属性是一个数组。Text属性是字符类型，List属性是数组， ListCount属性是数值类型，ListIndex属性也是数值类型。选项A) 和选项C) 是数值类型，而List1．Text是字符类型，所以这两个选项不是本题的答案；List1．Text属性表示最后一次选中项的文本，而选项List．List(ListCount-1)表示列表框中最后一个选项的文本，二者的含义不同，所以选项B) 不是本题的答案；List．ListIndex返回的是选中的表项的位置，与List．Text的属性值相同。
