Reading Another Application's Web.Config to get ConnectionString

Question

How can I read another application to get connectionString .. I have path of web.config File But there are multiple connection strings in it and I want to get the only non commented connection string.

<connectionStrings>
  <add name="DbConString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\abcd\Data\abcd.accdb;" providerName="System.Data.OleDb"/>
  <!--<add name="DbConString" connectionString="Persist Security Info=False;User ID=sa;Password=123;Initial Catalog=abc;Data Source=afrt-WIN7JPN-80\SQLEXPRESS" providerName="System.Data.SqlClient"/>-->
</connectionStrings>

How can I get the non commented DbConString

Answer 1

Done by simply reading Web.Config with XmlDocument

 string connStr = "";
 XmlDocument xdoc = new XmlDocument();
 xdoc.Load(WebConfigPath);
 XmlNode xnodes = xdoc.SelectSingleNode("/configuration/connectionStrings");

  foreach (XmlNode xnn in xnodes.ChildNodes)
  {
     if (xnn.NodeType == XmlNodeType.Comment)
     { 
     }
     else
     {
       connStr = xnn.Attributes["connectionString"].Value.ToString();
     }
  }

You can try this

var filePath = @"D:\PathToConfig\Web.config";
var map = new ExeConfigurationFileMap { ExeConfigFilename = filePath };
var configFile = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);

As shown here!
