从c＃WPF代码自动登录到Web浏览器

Question

I am trying to login to the site https://kite.zerodha.com/ from a Webbrowser control in my C# WPF application. I am stuck because of the way the source code of the site is written as for none of the Input / Action elements there is any ID/TAG/NAME by which I can get the element and pass my input from my program.

The source code of the site for the password field looks something like below :

<input type="password" maxlength="30" placeholder="" autocorrect="off" animate="true" label="" rules="[object Object]" dynamicwidthsize="8" autocomplete="off">

In my C# code on Loadcompletion of the browser I have got the HTML document as below:

htmldoc = LogInBrowser.Document as mshtml.HTMLDocument;

But now I am not able to proceed as to how can I access the password field and pass my input from my program.

Some guidance would be of great help!

Thanks, Nandy

You can achieve this by small trick. Pass your password in the OuterHtml of HTML element. Add the value element in the OuterHtml value=\\"Your_Password\\"

// Get password element
HtmlElement passwordElement = (from HtmlElement element in webBrowser1.Document.GetElementsByTagName("input") select element)
    .Where(x => x.GetAttribute("type") == "password").FirstOrDefault();

if (passwordElement != null)
{
    passwordElement.OuterHtml = "<input type=\"password\" maxlength=\"30\" placeholder=\"Password\" autocorrect=\"off\" animate=\"true\" label=\"\" rules=\"[object Object]\" dynamicWidthSize=\"8\" autocomplete=\"off\" value=\"Your_Password\">";
}
