title: Getting column description from datatable schema
body: <p>I want to know details of columns. I learnt it from Microsoft's site. But still I don't know how to get column's description. Below I got the code block from Microsoft Support site.</p>
  
  <pre><code>OleDbConnection cn = new OleDbConnection();
  OleDbCommand cmd = new OleDbCommand();
  DataTable schemaTable; 
  OleDbDataReader myReader; 
  
  cn.ConnectionString = "Provider=SQLOLEDB;Data Source=server;User ID=login;
                         Password=password;Initial Catalog=Northwind";
  cn.Open();
  cmd.Connection = cn;
  cmd.CommandText = "SELECT * FROM Employees";
  myReader = cmd.ExecuteReader(CommandBehavior.KeyInfo); 
  schemaTable = myReader.GetSchemaTable();
  foreach (DataRow myField in schemaTable.Rows){
      foreach (DataColumn myProperty in schemaTable.Columns) {
      Console.WriteLine(myProperty.ColumnName + " = " + myField[myProperty].ToString());
      }
      Console.WriteLine();
      Console.ReadLine();
  }
  myReader.Close();
  cn.Close();
  </code></pre>
  
  <p>Please, could you help me, in this code block, how do I get the column's description?</p>
