hi,
I am trying to create a XML file from a SQL Server database table. But it is showing an error. My code is :

using (StreamWriter sw = File.CreateText(path))
{
    string source = ConfigurationSettings.AppSettings["dbString"];
    SqlConnection con = new SqlConnection(source);
    SqlXmlCommand cmd = new SqlXmlCommand(source);
    cmd.CommandText = "select * from node_master";
    cmd.RootTag = "TREENODES";
    cmd.CommandType = SqlXmlCommandType.Sql;
    DataSet ds = new DataSet();
    SqlXmlAdapter xa = new SqlXmlAdapter(cmd);
    xa.Fill(ds);
    ds.WriteXml(sw, XmlWriteMode.IgnoreSchema);
}

But it is showing an "System error" in the Red line.
Error is:
Exception Details: Microsoft.Data.SqlXml.ConnectionStringNotSetExcept ion: System error.

How can I solve this problem?
