Question

我正在通过雅虎管道运行我的 Facebook 状态源，并将其输出/嵌入到我自己托管网站的页面上。

XML 提要包含日期。我想格式化日期但不知道该怎么做。 XML 部分是日期输出是...Thu, 14 Jul 2011 20:38:07 +0100 我希望它呈现类似 14/07/ 的内容2011年。

非常感谢任何帮助。

我有 C# 代码...

protected void Page_Load(object sender, EventArgs e)
    {

        WebRequest MyRssRequest = WebRequest.Create("http://pipes.yahoo.com/pipes/pipe.run?FacebookRssUrl=http%3A%2F%2Fwww.facebook.com%2Ffeeds%2Fpage.php%3Fid%3D456456456456456%26format%3Drss20&_id=456456456456456456464&_render=rss");
        WebResponse MyRssResponse = MyRssRequest.GetResponse();

        Stream MyRssStream = MyRssResponse.GetResponseStream();

        // Load previously created XML Document
        XmlDocument MyRssDocument = new XmlDocument();
        MyRssDocument.Load(MyRssStream);

        XmlNodeList MyRssList = MyRssDocument.SelectNodes("rss/channel/item");

        string sTitle = "";
        string sLink = "";
        string sDescription = "";

        // Iterate/Loop through RSS Feed items
        for (int i = 0; i < 3; i++)
        {
            XmlNode MyRssDetail;

            MyRssDetail = MyRssList.Item(i).SelectSingleNode("title");
            if (MyRssDetail != null)
                sTitle = MyRssDetail.InnerText;
            else
                sTitle = "";

            MyRssDetail = MyRssList.Item(i).SelectSingleNode("link");
            if (MyRssDetail != null)
                sLink = MyRssDetail.InnerText;
            else
                sLink = "";

            MyRssDetail = MyRssList.Item(i).SelectSingleNode("pubDate");
            if (MyRssDetail != null)
                sDescription = MyRssDetail.InnerText;

            else
            {
                sDescription = "";
            }

            // Now generating HTML table rows and cells based on Title,Link & Description
            HtmlTableCell block = new HtmlTableCell();
            block.InnerHtml = "<span style='font-weight:bold'><a href='" + sLink + "' target='new'>"+ sTitle + "</a></span>";
            HtmlTableRow row = new HtmlTableRow();
            row.Cells.Add(block);
            tbl_Feed_Reader.Rows.Add(row);
            HtmlTableCell block_description = new HtmlTableCell();
            block_description.InnerHtml = "<p align='justify'>" + sDescription + "</p>";
            HtmlTableRow row2 = new HtmlTableRow();
            row2.Cells.Add(block_description);
            tbl_Feed_Reader.Rows.Add(row2);
        }
    }

Answer 1

您可以将其解析为 DateTime 并以您想要的特定格式呈现。

var x = DateTime.Parse(MyRssDetail.InnerText);
//Your date format
sDescription = x.ToString("d MMM yyyy");

Answer 2

您可以使用 DateTime.Parse或 DateTime.ParseExact。

DateTime xmlDateTime = DateTime.Parse(xmlValue);

从那里，需要使用 DateTime.ToString()< 输出它/code>具有所需的格式参数（或任何内置的 ToShortDateString、ToLongDateString、ToShortTimeString 等）

xmlDateTime.ToShortDateString();

Answer 3

我会做类似的事情：

DateTime parsedDate=DateTime.Min;
if(DateTime.TryParse(xmlStringWithDate,ref parsedDate))
{
   //Do something useful with parsedDate since the parse was successful
}

Answer 4

您可以使用 String.Format 来执行此操作：

 sDescription = String.Format("{0:D}", MyRssDetail.InnerText);

或将其转换为日期，然后从那里开始：

sDescription = Convert.ToDateTime(MyRssDetail.InnerText).toShortDateString();

Answer 5

String.Format({0:D}, dateToFormat)

我假设你想做 pubDate？

sDescription = String.Format({0:D}, MyRssDetail.InnerText.ToDate())
