我的代码
HtmlElement btnSubmit = webBrowser1.Document.All["login"]; //获取登录对应元素
HtmlElement tbUserid = webBrowser1.Document.All["userName"]; //获取用户名对应元素
HtmlElement tbPasswd = webBrowser1.Document.All["passWord"]; //获取密码对应元素
if (tbUserid == null || tbPasswd == null )return;
tbUserid.SetAttribute("value", txtUseName.Text); //给用户名赋值
tbPasswd.SetAttribute("value", txtPassWord.Text); //给密码赋值
btnSubmit.InvokeMember("click"); //模拟点击登录按钮
做好后 可以输入字符 但按钮登录没反应不会跳转到登录后的页面 webbrowser
[解决办法]
login是Form，不是按钮吧
btnSubmit 取到值了吗？
btnSubmit.InvokeMember("click");改成btnSubmit.InvokeMember("submit");试试
[解决办法]
改成btnSubmit.InvokeMember("submit");
[解决办法]
btnSubmit.InvokeMember("submit");//试试这个，click是模拟点击事件
[解决办法]
你的这句代码：HtmlElement btnSubmit = webBrowser1.Document.All["login"];
获取的是form元素，form元素的提交是用Submit，如果你要用Click那么你就该获取到这个登录按钮元素：<input type="image" src="/abc/images/dl_13.jpg" onclick="return validate();" width="55" height="15">
