private void button_Click(object sender, EventArgs e) 
{ 
    // Check to see if web browser is at URL 
    if (webBrowser1.Url.ToString != "www.google.com" || webBrowser1.Url.ToString == null) 
{ 
    // Goto webpage 
    webBrowser1.Url = new Uri("www.google.ca"); 
} 
else { 
    webBrowser1.Document.GetElementById("first").InnerText = "blah"; 
    webBrowser1.Document.GetElementById("second").InnerText = "blah"; 
} 
} 

Answer 1

在这里你去。

private void button1_Click(object sender, EventArgs e) 
     { 
      webBrowser1.Url = new Uri("https://www.google.ca"); 

      // Check to see if web browser is at URL 
      if (webBrowser1.Url != null) 
      { 
       if (webBrowser1.Url.ToString() != "https://www.google.com" || webBrowser1.Url.ToString() == null) 
       { 
        // Goto webpage 
        webBrowser1.Url = new Uri("www.google.ca"); 
       } 
       else 
       { 
        webBrowser1.Document.GetElementById("first").InnerText = "blah"; 
        webBrowser1.Document.GetElementById("second").InnerText = "blah"; 
       } 
      } 

     } 

1）请使用带有URL的模式。

2）使用ToString（）作为函数。
