public void CreateDataAdapter(MySqlConnection myConnection)
{
  MySqlDataAdapter myAdapter = new MySqlDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection);
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.Fill(myDataSet,"Dept");
  //Get all data from all tables within the dataset
  foreach(DataTable myTable in myDataSet.Tables)
  {
    foreach(DataRow myRow in myTable.Rows)
    {
      foreach (DataColumn myColumn in myTable.Columns)
      {
        Console.Write(myRow[myColumn]+"\t");
      }
      Console.WriteLine();
    }
    Console.WriteLine();
  }
}

Visual Basic

Public Sub CreateDataAdapter(ByVal myConnection As MySqlConnection)
  Dim myAdapter As MySqlDataAdapter = New MySqlDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection)

  Dim myDataSet As DataSet = New DataSet
  myAdapter.Fill(myDataSet, "Dept")
  Dim myTable As DataTable
  Dim myRow As DataRow
  Dim myColumn As DataColumn
  ' Get all data from all tables within the dataset
  For Each myTable In myDataSet.Tables
    For Each myRow In myTable.Rows
      For Each myColumn In myTable.Columns
        Console.Write(myRow(myColumn) & Chr(9))
