c# - 在 WebBrowser 上选择特定的文本框并在其中写入

Question

how would I select a specific text box on a web browser (the default c# webbrowser) and write a string in it? I have been thinking of webrequests but that may be illegal due to the amount of packets you will send to the host server.

If you are just wanting to fill in a field, you need to use the DOM. Here are some examples that assume your browser is named browser and has navigated to google.com.

WPF

     mshtml.IHTMLDocument2 htmlDoc = browser.Document as mshtml.IHTMLDocument2;
     ((mshtml.HTMLInputElement)htmlDoc.all.item("lst-ib")).value = "wpf web browser access dom";

WinForms

     HtmlDocument htmlDoc = browser.Document;
     htmlDoc.All["lst-ib"].InnerText = "c# web browser access dom";
