C# 在C中使用mshtml控件获取特定选项卡的内容

有人能帮我解决这个问题吗

您发布的代码有什么问题吗？无法选择选项卡第1节和第3节java脚本。第2节处于默认状态。

 <UL CLASS="littletab">
<LI CLASS="littletabitem" ID="forwardTo1">
    <A HREF="javascript:void(0)">Section 1</A>
    </LI>
<LI CLASS="littletabitem is-current">
    <A HREF="javascript:void(0)">Section 2</A>
    </LI>
<LI CLASS="littletabitem" ID="forwardTo3">
    <A HREF="javascript:void(0)">Section 3</A>
    </LI>
</UL>

                HTMLDocument myDoc2 = new HTMLDocumentClass();
                myDoc2 = (HTMLDocument)IE.Document;
                string Content_main2 = ((mshtml.HTMLDocumentClass)(IE.Document)).body.innerHTML;
                    HTMLAnchorElement submitnextnext = (HTMLAnchorElement)myDoc.all.item("forwardTo1", 0);
                submitnextnext.click();
