推荐答案

bool startFromScratch = false;

//...

startFromScratchButton.Click += (sender, eventArgs) => {
   startFromScratch = true;
   webBrowser.Navigate((Uri)null); //navigate to empty   
} //startFromScratchButton.Click

webBrowser.Navigated += (sender, eventArgs) => {
   if (startFromScratch) {
      var document = webBrowser.Document;
      var body = document.Body;
      document.Body.InnerHtml = "<p>some paragraph content</p>";
   } //if
}; //webBrowser.Navigated
