问题 单项选择题

设窗体上有名称为Option1的单选按钮，且程序中有语句： If Option1.Value=True Then 下面语句中与该语句不等价的是______。

A．If Option1.Value Then

B．If Option1=True Then

C．If Value=True Then

D．If Option1 Then

答案

参考答案：C

解析： A选项中Option1.Value可作为一个条件表达式，它返回的是单选按钮Value属性的属性值，根据属性值就可以判断出单选按钮是否被选中；B选项中Option1等价于Option1.Value；D选项与A选项等价，故A、B、D选项均与程序中语句等价；C选项中Value是属性名，前面必须加控件名才能用，不能单独使用，故C选项错误。
