Question

c# webbrowser控件中,选定radio项的问题，
做一个自动答卷的小工具，分析网页代码发现选项的文字没有写在input中，而是放在了input后面的label中，这下我怎么才能确定正确答案究竟是ABCD哪个选项呢？

 A:<input id="GridView1_ctl17_RadioButton1" type="radio" name="GridView1$ctl17$Sl" value="RadioButton1" /><label for="GridView1_ctl17_RadioButton1">A. which 　</label>

B:<input id="GridView1_ctl17_RadioButton2" type="radio" name="GridView1$ctl17$Sl" value="RadioButton2" /><label for="GridView1_ctl17_RadioButton2">B. with whom 　</label>

C:<input id="GridView1_ctl17_RadioButton3" type="radio" name="GridView1$ctl17$Sl" value="RadioButton3" /><label for="GridView1_ctl17_RadioButton3">C. whom 　</label>

D:<input id="GridView1_ctl17_RadioButton4" type="radio" name="GridView1$ctl17$Sl" value="RadioButton4" /><label for="GridView1_ctl17_RadioButton4">D. with which</label>

Answer 1

你先获取每个选项，然后得到后面label对应的字符串，然后你答题程序比较选择对应的
