If this method returns false, the database is corrupt, and your application should call the Repair method to correct the problem.

Example

Dim engine As New SqlCeEngine("Data Source = AdventureWorks.sdf")

If False = engine.Verify() Then
    MessageBox.Show("Database is corrupted.")
    engine.Repair(Nothing, RepairOption.RecoverCorruptedRows)
End If

SqlCeEngine engine = new SqlCeEngine("Data Source = AdventureWorks.sdf");

if (false == engine.Verify())
{
    MessageBox.Show("Database is corrupted.");
    engine.Repair(null, RepairOption.RecoverCorruptedRows);
}
