Question

I am trying to make an RSS Feed with asp.net,sql and xml. I am getting an error

Compiler Error Message: CS0103: The name ‘MyConnString’ does not exist in the current context’ on line 22 ‘SqlConnection objConnection = new SqlConnection(‘MyConnString’);

My web config contains

<connectionStrings>     <add name='MyConnString' connectionString='      providerName='System.Data.SqlClient' />   </connectionStrings> 

Here is the code

<%@ Page Language='C#' MasterPageFile='ContentMasterPage.master' Debug='true' %>  <%@ Import Namespace='System.Xml'%> <%@ Import Namespace='System.Data' %> <%@ Import Namespace='System.Data.SqlClient' %>  <script runat='server'>     void Page_load(object sender, System.EventArgs e)     {         Response.Clear();         Response.ContentType = 'text/xml';         XmlTextWriter objX = new XmlTextWriter(Response.OutputStream, Encoding.UTF8);         objX.WriteStartDocument();         objX.WriteStartElement('rss');         objX.WriteAttributeString('version', '2.0');         objX.WriteElementString('title', 'News');         objX.WriteElementString('link', 'http://news.ca/news.aspx');         objX.WriteElementString('description', 'The latest headlines');         objX.WriteElementString('copyright', '(c)2009, News Club, All rights reserved.');         objX.WriteElementString('ttl', '5');         SqlConnection objConnection = new SqlConnection('MyConnString');         objConnection.Open();         string sql = 'SELECT TOP 5 Title, Description, ArticleID, DatePulished FROM articles ORDER BY DatePublished DESC';         SqlCommand objCommand = new SqlCommand(sql, objConnection);         SqlDataReader objReader = objCommand.ExecuteReader();         while (objReader.Read())         {             objX.WriteStartElement('item');             objX.WriteElementString('title', objReader.GetString(0));             objX.WriteElementString('description', objReader.GetString(1));             objX.WriteElementString('link', ('http://news.ca/GetArticle.aspx?id=' + objReader.GetInt32(2).ToString()));             objX.WriteElementString('pubDate', objReader.GetDateTime(3).ToString('R'));             objX.WriteEndElement();         }         objReader.Close();         objConnection.Close();         objX.WriteEndElement();         objX.WriteEndElement();         objX.WriteEndDocument();         objX.Flush();         objX.Close();         Response.End();     } </script> 

Answer 1

SqlConnection objConnection = new SqlConnection('MyConnString'); 

This is the line that the compiler is having a difficult time with. Did you replace your actually connection string with ‘MyConnString’ or is MyConnString supposed to be a string value on the page?

I have a similar line of code in my app:

SqlConnection oConn= new SqlConnection(_connString); 

You can also get this value from the Web.Config

SqlConnection oConn = new SqlConnection(ConfigurationManager.ConnectionStrings['MyConnString'].ConnectionString);
