Web瀏覽器控件

Question

你好，我使用此代碼：

private void Form1_Load(object sender, EventArgs e) 
    { 
     webBrowser1.Navigate("about:blank"); 

     HtmlDocument doc = webBrowser1.Document; 
     doc.Write("<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan."); 
    } 
    private void button1_Click(object sender, EventArgs e) 
    { 
     webBrowser1.Navigate("about:blank"); 
     HtmlDocument doc = webBrowser1.Document; 
     doc.Write("<b><i>My Name</i> is Not </b> Khan.<b>"); 
    } 

但是當我點擊按鈕，然後webBrowser1顯示空白。

試試下面的代碼：

private void Form1_Load(object sender, EventArgs e) 
    { 
     string strText = "<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan.<b><i>My Name</i> is Not </b> Khan."; 
     webBrowser1.Navigate("about:blank"); 
     HtmlDocument objHtmlDoc = this.webBrowser1.Document; 
     objHtmlDoc.Write(String.Empty); 
     webBrowser1.DocumentText = strText; 
    } 
    private void button1_Click(object sender, EventArgs e) 
    { 
     string strText="<b><i>My Name</i> is Not </b> Khan.<b>"; 
     webBrowser1.Navigate("about:blank"); 
     HtmlDocument objHtmlDoc = this.webBrowser1.Document; 
     objHtmlDoc.Write(String.Empty); 
     webBrowser1.DocumentText = strText; 
    }
