C#中如何自動檢查webbrowser文檔加載完畢

.NET

C# winform 窗體上有三個控件兩個button（button1和button2）和一個webbrowser,我在button1中檢測webbroser加載文檔是否完畢，如果完畢則點擊button2，否則等待 webbrowser1加載完畢，這個邏輯應該怎么表達呢我目前是這樣搞的在button1_click函數(shù)中webBrowser1.Navigate(s); while(webBrowser1.ReadyState!=WebBrowserReadyState.Complete) { }; btnNextPage_Click(null, null);結果發(fā)現(xiàn)的問題是，函數(shù)死循環(huán)在while語句

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            button2_Click(button2, null);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            if (webBrowser1.ReadyState == WebBrowserReadyState.Complete)
            {
                button2_Click(button2, null);
            }
            else
            {
                webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
            }
        }
