问题描述
我无法使它正常工作.我有一个MemoryStream对象.这个班有一个Position属性，可以告诉您已读取了多少字节.
I cannot get this to work. I have a MemoryStream object. This classhas a Position property that tells you how many bytes you have read.
我要删除的是0到Position-1之间的所有字节
What I want to do is to delete all the bytes between 0 and Position-1
我尝试过:
MemoryStream ms = ...
ms.SetLength(ms.Length - ms.Position);
但是在某些时候我的数据已损坏.
but at some point my data gets corrupted.
所以我最终这样做了
MemoryStream ms = ...
byte[] rest = new byte[ms.Length - ms.Position];
ms.Read(rest, 0, (int)(ms.Length - ms.Position));
ms.Dispose();
ms = new MemoryStream();
ms.Write(rest, 0, rest.Length);
有效，但效率不高.
有什么想法可以使它正常工作吗?
Any ideas how I can get this to work?
谢谢
推荐答案
您不能从MemoryStream中删除数据-最干净的方法是根据所需数据创建新的内存流:
You can't delete data from a MemoryStream - the cleanest would be to create a new memory stream based on the data you want:
MemoryStream ms = new MemoryStream(someData);
//ms.Position changes here
//...
byte[] data = ms.ToArray().Skip((int)ms.Position).ToArray();
ms = new MemoryStream(data);
