   // presuming a DataGrid is displaying more than one table, get its DataSet.
   DataSet thisDataSet = (DataSet)DataGrid1.DataSource;
   // Get the DataTableCollection.
   DataTableCollection tablesCollection = thisDataSet.Tables;
   // Iterate through the collection to get each table name. 
   for (int i = 0; i < tablesCollection.Count; i++)
      Console.WriteLine(tablesCollection[i].TableName);
}
