MSDN是你的朋友。確保你有'http：//'前綴並嘗試使用Navigate(Uri url)過載。

// Navigates to the given URL if it is valid. 
private void Navigate(String address) 
{ 
    if (String.IsNullOrEmpty(address)) 
     return; 

    if (address.Equals("about:blank")) 
     return; 

    if (!address.StartsWith("http://") && !address.StartsWith("https://")) 
    { 
     address = "http://" + address; 
    } 
    try 
    { 
     webBrowser.Navigate(new Uri(address)); 
    } 
    catch (System.UriFormatException) 
    { 
     return; 
    } 
}

您需要處理網頁瀏覽器的DocumentCompleted事件。

去通過下面的代碼：

private void goButton_Click(object sender, EventArgs e) 
    { 
     WebBrowser wb = new WebBrowser(); 
     wb.AllowNavigation = true; 

     wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wb_DocumentCompleted); 

     wb.Navigate(loginURL.Text + "/auth/login"); 

       } 

    private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) 
    { 
     WebBrowser wb = sender as WebBrowser; 
     // wb.Document is not null at this point 
    }
