IDisposable对象的问题
代码如下：

using (MemoryStream ms = new MemoryStream())
{
using (BinaryWriter bw = new BinaryWriter(ms))
{
bw.Write(true);
}
ms.WriteByte((byte)1); // 此行出错: System.ObjectDisposedException
ms.Close();
}

如何让bw在回收的时候不释放ms?

[解决办法]
没办法,ms和bw其实是同1个
using (MemoryStream ms = new MemoryStream())
{
BinaryWriter bw = new BinaryWriter(ms)
bw.Write(true);
ms.WriteByte((byte)1);
ms.Flush();
}
[解决办法]
把内层的using去掉,using{}内会自动释放托管资源
[解决办法]
GC.KEEPALIVE(bw)
