WPF使用Webbrowser操作网页的主要代码

using mshtml;

IHTMLDocument2 doc2=(IHTMLDocument)webbrowser1.Document;
IHTMLElement img=(IHTMLElement)doc2.all.item("regimg",0);
string imgUrl=(string)img.getAttribute("src");

IHTMLElement loginName=(IHTMLElement)doc2.all.item("loginname",0);
IHTMLElement loginPW=(IHTMLElement)doc2.all.item("password",0);
IHTMLElement loingYZM=(IHTMLElement)doc2.all.item("regcode",0);
IHTMLElement loginBT=(IHTMLElement)doc2.all.item("formsubmit",0);

loginName.setAttribute("value",tbLoginName.Text);
loginPW.setAttribute("value",tbLoginPassWord.Password);
loginYZM.setAttribute("value",tbYZ.Text);

loginBT.click();

IHTMLwindow win=(IHTMLWindow2)doc2.parentWindows;
win.execScript("alert(‘hello!‘)","javascript");

webbrowser1.InvokeScript("eval","alert(‘hello!‘)");

private voie webbrowser1_navigated(object sender,WebBroserNavigatedEventArgs e)
{
    IHTMLWindow2 win=(IHTMLWindow2)webbrowser1.Document.Window.DomWindow;
    string s=@"window.alert=null; window.onerror=null;window.confirm=null; windows.open=null; window.showModalDialg=null;";
    win.execScript(s,"javascript");
}

[ComVisible(true)]  //这句要加到类定义前，可与COM通信

private void webbrowser1_Navigated(objec sender,WebBrowserNavigatedEventargs e)
{
    IHTMLWindow2 win=（IHTMLWindow2)webbrowser1.Document.Window.DomWindow;
    //假设把alert消息传出来处理
    string s=@"function alert(str){window.external.procMessage(str);}";
    win.execScript(s,"javascript");
    webbrowser1.ObjectForScripting=this;  //指定脚本消息送到当前实例处理
}

//处理脚本消息的方法
public void procMessage(string s)
{
    MessageBox.Show("脚本消息："+s);
}
