怎样保证结构体是在一片连续的空间上 c#的

Question

结构如下 public struct UpdateKeyWords    {        public byte m_ucTableType;        public byte m_ucUpdateType;        public byte m_ucOperateType;        public UInt32 counts;         public SubKeyword[] keys;//动态开辟    }     public struct SubKeyword      {        public UInt32 m_uiWordLen;        public byte[] m_szWord;//动态开辟    }

Answer 1

在结构体上面加上这个属性　

    [StructLayout(LayoutKind.Sequential, Pack = 0)]

    public struct SubKeyword 

    {
        public UInt32 m_uiWordLen;

　　　[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20)]
        public byte[] m_szWord;//动态开辟
    }
