How to convert HtmlDocument.DomDocument to string?

推荐答案

这个例子有点复杂，但假设你有使用称为 webBrowser1 的WebBrowser控件， Form1 的形式，变量内容将包含形成文档的标记：

This example is a bit convoluted, but, assuming you have a form called Form1, with a WebBrowser control called webBrowser1, the variable content will contain the markup that forms the document:

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser1.Url = new Uri(@"http://www.robertwray.co.uk/");          
}

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    var document = webBrowser1.Document;
    var documentAsIHtmlDocument3 = (mshtml.IHTMLDocument3)document.DomDocument;

    var content = documentAsIHtmlDocument3.documentElement.innerHTML;
}

从 HtmlDocument.DomDocument 在 webBrowser1_DocumentCompleted 事件处理程序中。

注意： mshtml 是通过向Microsoft HTML对象库（aka：mshtml.dll）添加COM引用获得的。

Note: mshtml is obtained by adding a COM reference to 'Microsoft HTML Object Library` (aka: mshtml.dll)
