用其他序列替换一个字节序列的最有效方法

这是一个简短的应用程序，可以满足您的需求：

    static void Main(string[] args)
    {
        byte [] bArray = new byte[] {11, 67, 67, 67, 33, 34, 67, 67, 11, 33, 67, 67, 67, 67};
        byte[] result = Replace(bArray, new byte[] {67, 67, 67}, new byte[] {90});
        foreach (byte b in result)
        {
            Console.WriteLine(b);
        }
    }
    private static byte [] Replace(byte[] input, byte[] pattern, byte[] replacement)
    {
        if (pattern.Length == 0)
        {
            return input;
        }
        List<byte> result = new List<byte>();
        int i;
        for (i = 0; i <= input.Length - pattern.Length; i++)
        {
            bool foundMatch = true;
            for (int j = 0; j < pattern.Length; j++)
            {
                if (input[i + j] != pattern[j])
                {
                    foundMatch = false;
                    break;
                }
            }
            if (foundMatch)
            {
                result.AddRange(replacement);
                i += pattern.Length - 1;
            }
            else
            {
                result.Add(input[i]);
            }
        }
        for (; i < input.Length; i++ )
        {
            result.Add(input[i]);
        }
        return result.ToArray();
    }
