您必须添加对 Microsoft.mshtml 的引用，当然还要等待文档完成加载.这将保存在 System.Windows.Forms.WebBrowser webBrowser1 组件中加载的图像 - 甚至是您不想要的图像.
You have to add a reference to Microsoft.mshtml and of course wait for the document to finish loading. This will save the images loaded in a System.Windows.Forms.WebBrowser webBrowser1 component - even the ones you don't want.
IHTMLDocument2 doc = (IHTMLDocument2) webBrowser1.Document.DomDocument;
IHTMLControlRange imgRange = (IHTMLControlRange) ((HTMLBody) doc.body).createControlRange();
foreach (IHTMLImgElement img in doc.images)
{
imgRange.add((IHTMLControlElement) img);
imgRange.execCommand("Copy", false, null);
using (Bitmap bmp = (Bitmap) Clipboard.GetDataObject().GetData(DataFormats.Bitmap))
{
bmp.Save(@"C:"+img.nameProp);
}
}
