C#: How do you implement the template method pattern?

1public abstract class DataProcessor
2{
3    public void Process()
4    {
5        ReadData();
6        TransformData();
7        WriteData();
8    }
9
10    protected abstract void ReadData();
11    protected abstract void TransformData();
12    protected abstract void WriteData();
13}

15public class CsvProcessor : DataProcessor
16{
17    protected override void ReadData() { /* CSV */ }
18    protected override void TransformData() { /* Transform */ }
19    protected override void WriteData() { /* Write */ }
20}
