问题描述
我应该分配内存或存储流的只是对象：
这是OK？
Should I allocate the memory or just the object of the memory stream:Is this OK?
MemoryStream memoryStream = new MemoryStream();
bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Jpeg);
如果我需要定义MemoryStream的大小，如何从位图得到它？
If I need to define the MemoryStream size, how can I get it from Bitmap?
推荐答案
.NET是一个管理环境：具体而言，内存分配代表您的.NET运行时通常是管理。你通常不需要自己分配内存。
.NET is a managed environment: specifically, memory allocation is usually managed on your behalf by the .NET runtime. You don't typically need to allocate the memory yourself.
不过，有时你需要使用通知运行时，当你有记忆完成关闭（）或的Dispose（）。在使用语句可用于包装资源，如的MemoryStream 来告诉大家，内存可以被回收的运行时间。
Sometimes, however, you do need to inform the runtime when you've finished with memory by using Close() or Dispose(). The using statement can be used to wrap a resource such as MemoryStream to tell the runtime that the memory can be reclaimed.
