插入缓冲区的有效方法(Efficient way to insert into buffer)

 假设我将一个流读入缓冲区，并且我希望在此缓冲区中进行多次插入。 是否有一些有效的帮助对象我可以调用来帮助解决这个问题。 假设我想在位置100处插入10个字节的长度，然后在位置500处插入20个字节的长度（在插入前10个字节后现在将为510）。 我所追求的是跟踪多次插入时实际插入的位置（否则我必须通过我已插入的内容移动所有地址）。 
 
 滚动我自己很简单，但我想知道我是否在这里重新发明轮子，这已经包含在某些.NET构造中了？ 

Let's say I read a stream into a buffer, and I want to make multiple insertions into this buffer. Is there some efficient helper object I can call to help with this. Say if I want to make an insertion of 10 bytes length at position 100, then 20 bytes length into position 500 (which would now be 510 after inserting the first 10 bytes). What I'm after is something to keep track of where to actually make the insertions when inserting multiple times (otherwise I have to shift all address by the what I've already inserted).
 
It would be simple to roll my own, but I was wondering if I'm reinventing the wheel here, and this is already included in some .NET construct?
