title: Using GetSchemaTable() to retrieve only column names
body: <p>Is it possible to use <code>GetSchemaTable()</code> to retrieve only column names? </p>
  
  <p>I have been trying to retrieve Column names (only) using this method, is it possible.</p>
  
  <pre><code>  DataTable table = myReader.GetSchemaTable();
  
    foreach (DataRow myField in table.Rows)
    {
        foreach (DataColumn myProperty in table.Columns)
        {
            fileconnectiongrid.Rows.Add(myProperty.ColumnName + " = " 
                              + myField[myProperty].ToString());
        }
    }
  </code></pre>
  
  <p>This code retrieves a lot of table data unwanted, I only need a list containing 
  column names!:</p>
