    Example
    The following example creates a SqlDataAdapter, sets some of its properties, retrieves data from a table, and displays it.
    public void CreateDataAdapter(SqlConnection myConnection)
    {
      SqlDataAdapter myAdapter = new SqlDataAdapter();
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
      DataSet myDataSet = new DataSet();
      myAdapter.SelectCommand = new SqlCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection);
      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();
      }
    }
    Public Sub CreateDataAdapter(ByVal myConnection As SqlConnection)
      Dim myAdapter As SqlDataAdapter = New SqlDataAdapter
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
      Dim myDataSet As DataSet = New DataSet
      myAdapter.SelectCommand = New SqlCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection)
      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))
          Next myColumn
          Console.WriteLine()
        Next myRow
        Console.WriteLine()
      Next myTable
    End Sub
