Examples

The following example shows a class derived from the DataSet class. The ShouldSerializeTables method is called from within functions in the derived class.

public  class DerivedDataSet:System.Data.DataSet
{
    public void ResetDataSetRelations()
    {
        // Check the ShouldPersistTable method
        // before invoking Reset.
        if(!this.ShouldSerializeTables())
        {
            this.Reset();
        }
    }
}

Public Class DerivedDataSet
    Inherits System.Data.DataSet
    
    Public Sub ResetDataSetRelations()
        ' Check the ShouldPersistTable method 
        ' before invoking Reset.
        If Not Me.ShouldSerializeTables() Then
            Me.Reset()
        End If
    End Sub
End Class
