什么是C＃中用于Java中标记和重置方法的等效方法

Question

I am trying to convert a java class which extends BufferedInputStream class. It uses mark(1024) which I think it means the cursor will move to position 1024 and last it invokes reset() method. Now I have changed the class to inherit from BufferedStream in System.IO namespace, but I don't know whether there are equivalent methods for mark(int) and reset() methods in .net.

Answer 1

There are no equivalent methods in .NET. mark marks the current position as the position reset should jump to.

But you can implement simplified versions of them yourself:

public class YourClass
{
    private int _resetPosition;

    public void Mark()
    {
        _resetPosition = Position;
    }

    public void Reset()
    {
        Position = _resetPosition;
    }
}
