webBrowser控件實現網頁時實現進度顯示

由於網頁較大，在軟件中用webBrowser加載時，經常加載好半天，給人的感覺就是一片空白。所以必需要用進度條來解決了，用c#中提供的progressBar1實現起來就很簡單。

核心實現代碼：

以下爲引用的內容：
 private void Fmain_Load(object sender, EventArgs e)
        {
          Uri strurl = new Uri("

http://www.cn-web.com");
            webBrowser1.Url = strurl ;
            webBrowser1.ProgressChanged += new WebBrowserProgressChangedEventHandler(webBrowser1_ProgressChanged);

        }
        private void webBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
        {
            progressBar1.Visible = true;
            if ((e.CurrentProgress > 0) && (e.MaximumProgress > 0))
            {
                progressBar1.Maximum = Convert.ToInt32(e.MaximumProgress);//設置正在加載的文檔總字節數
                progressBar1.Step = Convert.ToInt32(e.CurrentProgress);////獲取已下載文檔的字節數
                progressBar1.PerformStep();
            }
            else if (webBrowser1.ReadyState == WebBrowserReadyState.Complete)//加載完成後隱藏進度條
            {
                progressBar1.Value = 0;
                progressBar1.Visible = false;
            }

        }
