こんなのはどうかね
public abstract class ReaderWriter<T> : IDisposable
{
protected FileStream stream;
protected BinaryWriter writer;
protected BinaryReader reader;
public abstract void Write(T item);
public abstract T Read();
public virtual void Seek(long offset, SeekOrigin origin) { this.stream.Seek(offset, origin); }
public void Dispose()
{
if (this.reader != null) this.reader.Close();
if (this.writer != null) this.writer.Close();
if (this.stream != null) this.stream.Close();
}
}
public class IntReaderWriter : ReaderWriter<int>
{
public IntReaderWriter(string fileName)
{
this.stream = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite);
this.reader = new BinaryReader(this.stream);
this.writer = new BinaryWriter(this.stream);
}
public override void Write(int item) { this.writer.Write(item); }
public override int Read() { return this.reader.ReadInt32(); }
}
