Examples

The following example uses the CanRemove to test whether each table can be removed from a DataSet. If so, the Remove method is called to remove the table.

private void RemoveTables()
{
    DataTable table;

    // presuming a DataGrid is displaying more than one table, get its DataSet.
    DataSet thisDataSet = (DataSet)DataGrid1.DataSource;
    while (thisDataSet.Tables.Count > 0)
    {
        table = thisDataSet.Tables[0];
        if (thisDataSet.Tables.CanRemove(table))
            thisDataSet.Tables.Remove(table);
    }
}
Private Sub RemoveTables()
    ' Presuming a DataGrid is displaying more than one table, 
    ' get its DataSet.
    Dim thisDataSet As DataSet = CType(DataGrid1.DataSource, DataSet)
    Do While thisDataSet.Tables.Count > 0
       Dim table As DataTable = thisDataSet.Tables(0)
       If thisDataSet.Tables.CanRemove(table) Then
          thisDataSet.Tables.Remove(table)
       End If
    Loop
End Sub
