WebBrowser control execution script in WinForm

In practical applications we may need the WebBrowser control to proactively execute the script we need, and there are two ways to execute the script now.

1, WebBrowser control loading script, simple and convenient, suitable for short scripts, unable to perform complex operations.

Webbrowser.navigate ("javascript:editor.areaToFrame ();d Ocument.getelementbyid (' articlepostbtn '). Click (); ");

The equivalent of you in the browser address bar, directly input script to execute.

2, using the dynamic library provided by Microsoft, namely Microsoft.mshtml.dll.

// Introducing Namespaces using mshtml; // get DOM Object IHTMLDocument2 Doc2 = (IHTMLDocument2) webBrowser.Document.DomDocument; // Execute Script " JavaScript ");

When adding a reference, there may be a case where the assembly cannot be found, and the direct Baidu download is available. Please remember the unique name "Microsoft.mshtml.dll".
