Circular Buffer for .NET

Actually I think I missunderstand the way your CircularBuffer works.

I'd like to do this :

            int capacity = 5;
            var buffer = new CircularBuffer<byte>(capacity, true);
            for (byte i = 0; i < capacity * 3; ++i)
                buffer.Put(i);

and have in the buffer { 10, 11, 12, 13, 14, 15 }

Is it possible ?

I guess AllowOverflow is the property to choose whether one CircularBuffer can overwrite his old values. If it's the case, it doesn't work when you reach the buffer capacity. It will cause an IndexOutOfRangeException in the Put method because of this :

buffer[tail] = item;

if (tail++ == capacity)

tail = 0

buffer[tail] = item;
if (tail++ == capacity)
    tail = 0;

When entering the Put method, if tail is equal to the buffer capacity - 1 then tail will be equal to the capacity when exiting. The next time we enter Put, tail will be equal to the buffer capacity and it will crash. Maybe the code should have been :

buffer[tail] = item;
if (++tail == capacity)
    tail = 0;
