Question

我使用下面的代码（aspx.cs）创建了xml文件，现在我尝试使用xslt和literal控件在我的页面上显示xml文件（查看我的aspx）

ASPX：

                <asp:Literal ID="RssHtml" runat="server" />

aspx.cs：

使用System; 使用System.Collections.Generic; 使用System.Linq; 使用System.Web; 使用System.Web.UI; 使用System.Web.UI.WebControls; 使用System.Data.SqlClient; 使用System.Xml; 使用System.Text; 使用System.Configuration; 使用System.IO; 使用System.Xml.Xsl;

public partial class Rss：System.Web.UI.Page { protected void Page_Load（object sender，EventArgs e） {

Response.Clear();
Response.ContentType = "application/rss+xml";
XmlTextWriter objX = new XmlTextWriter(Server.MapPath("App_Code/RssDef.xml"), Encoding.UTF8);
objX.WriteStartDocument();
objX.WriteStartElement("rss");
objX.WriteAttributeString("version", "2.0");
objX.WriteStartElement("channel");

SqlCommand cmd = new SqlCommand("Select * from RssFeeds", new SqlConnection(ConfigurationManager.ConnectionStrings["igroup13_test1ConnectionString"].ConnectionString));
cmd.Connection.Open();
SqlDataReader dr = cmd.ExecuteReader();

objX.WriteElementString("title", "RSS.....");
objX.WriteElementString("link", "");
objX.WriteElementString("description", "desc");
objX.WriteElementString("language", "en-us");
objX.WriteElementString("ttl", "60");
objX.WriteElementString("lastBuildDate", String.Format("{0:R}", DateTime.Now));

while (dr.Read())
{
    objX.WriteStartElement("item");
    objX.WriteElementString("title", dr["title"].ToString());
    objX.WriteElementString("link", "");
    objX.WriteElementString("description", dr["description"].ToString());
    objX.WriteElementString("pubDate", String.Format("{0:R}", dr["publishDate"]));
    objX.WriteEndElement();
    //objX.WriteEndElement();
}

objX.WriteEndElement();
objX.WriteEndElement();
objX.WriteEndDocument();
objX.Flush();
objX.Close();
Response.End();


#region load the XML file
// Use my local XML file (that I've created)
String strXmlSrc = Server.MapPath("~/App_Code/RssDef.xml");

//  Load the XML file into the XmlDocument object.
XmlDocument myXmlDoc = new XmlDocument();
try
{
    myXmlDoc.Load(strXmlSrc);
}
catch (Exception ex)
{
    Response.Write("error in loading XML document " + ex.Message);
    return;
}
#endregion

#region load the XSLT file
//  Load our XSL file into the Xsl Transform object.
String strXslFile = Server.MapPath("~/App_Data/Def.xslt");
XslCompiledTransform myXslDoc = new XslCompiledTransform(true);
try
{
    myXslDoc.Load(strXslFile);
}
catch (Exception ex)
{
    Response.Write("error in loading XSLT document " + ex.Message);
    return;
}
#endregion

#region Transform the XML into XHTML
//  Create a StringBuilder and then point a StringWriter at it.
//  I'm using this to hold the HTML output by the Transform method
StringBuilder myStringBuilder = new StringBuilder();
StringWriter myStringWriter = new StringWriter(myStringBuilder);

try
{
    myXslDoc.Transform(myXmlDoc, null, myStringWriter);
}
catch (Exception ex)
{
    Response.Write("error in transforming the document " + ex.Message);
    return;
}
#endregion

#region Write to the HTML Page
//  Take theresulting HTML and display it via an ASP.NET
//  literal control.
RssHtml.Text = myStringBuilder.ToString();
#endregion


}

}

XSLT：

<xsl:for-each select="rss/channel">
  <h2>
    <a href="{link}">
      <xsl:value-of select="title" />        
    </a>

  </h2>
  <h4>
    <xsl:value-of select="description"/>
  </h4>
</xsl:for-each>

<ul>
  <xsl:for-each select="rss/channel/item">
    <li>
      <a href="{link}">
        <strong>
          <xsl:value-of select="title" />

        </strong>
      </a>

    </li>

    <xsl:value-of select="descreption"/>
    <br/>
    <xsl:value-of select="pubDate"/>

  </xsl:for-each>
</ul>

我做错了什么？

我认为误解Response.End（）的错误调用“将所有当前缓冲的输出发送到客户端，停止执行页面，并引发EndRequest事件。”

Msdn link to Respons.End description

您应该从代码段中删除该行
