C＃RSS聚合，如何以編程方式格式化文本

Question

我試圖構建一個新聞饋送應用程序，並且遇到格式化結果的麻煩，我確信這個問題只是缺乏經驗。第一個是item.summary.text拉過一連串的鏈接通過摘要

我遇到的另一個問題是大膽所有的標題和改變它們的顏色我也使用豐富的文本框這可能不是代表數據的最佳方式。

而是一個RichTextBox的，你可以使用一個控制是比較友好的HTML像WebBrowser控制。然後，您可以使用CSS構建HTML格式的字符串&。假設您將一個名爲webBrowser的WebBrowser控件添加到您的表單中。然後，您可以像這樣的東西替換當前foreach循環：

var text = new StringBuilder(); 

foreach (SyndicationItem item in feed.Items) 
{ 
    text.AppendFormat("<p style='font-family:arial;color:red;font-size:20;font-weight:bold;'>Title: {0}</p>", item.Title.Text); 
    text.AppendLine("</br>"); 
    text.AppendLine("</br>"); 

    text.AppendFormat("<p style='font-family:arial;font-size:20;'>Date: {0:yyyy/MM/dd H:MM:ss}</p>", item.PublishDate); 
    text.AppendLine("</br>"); 
    text.AppendLine("</br>"); 

    text.AppendFormat("<p style='font-family:arial;font-size:20;'>Summary: {0}</p>", item.Summary.Text); 
    text.AppendLine("</br>"); 
    text.AppendLine("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"); 
    text.AppendLine("</br>"); 
    text.AppendLine("</br>"); 
} 

webBrowser.DocumentText = text.ToString();
