如何在C#中将结构转换为字节数组？

我已经定义了这样的结构:

public struct CIFSPacket
{
    public uint protocolIdentifier; //The value must be "0xFF+'SMB'".
    public byte command;

    public byte errorClass;
    public byte reserved;
    public ushort error;

    public byte flags;

    //Here there are 14 bytes of data which is used differently among different dialects.
    //I do want the flags2. However, so I'll try parsing them.
    public ushort flags2;

    public ushort treeId;
    public ushort processId;
    public ushort userId;
    public ushort multiplexId;

    //Trans request
    public byte wordCount;//Count of parameter words defining the data …

I received some data (many times) which are encapsulated inside a struct. what I need to do is write them to a file (binary) to restore the data. how will you do it?

我可以struct直接序列化类型,因为它是一个值类型.

我已经在课堂上使用它,但想知道它是否可以单独使用结构.

例如

struct student
{
   name string; --string is a reference type
   age int;
   designation string; --string is a reference type
   salary double;
};

class foo
{
 foo(){
   student s;
   s.name = "example";

   serialize(s);
  }
}

这个链接说 "我试过让我的struct实现ISerializable,但我无法实现所需的构造函数,因为这是一个结构而不是一个对象."

我是C#的新手.
我试图理解为什么结构大小增长.
即:

struct Test
{
    float x;
    int y;
    char z;
}

Test结构的大小实际上是10个字节(float = 4,int = 4,char = 2).
但是,当我试图用Marshal.SizeOf(..)方法获得sizeof结构时,我得到了12.
在C++中我做pragma pack(1)了防止这个但是我怎么能在C#中做到这一点？

另一个问题:
当我试图将Test结构转换为字节数组时,如果结构不是[Serialize]我得到的字节数组大小为12字节为例外(或不是),但如果结构是[Serialize]我得到大小为170字节的字节数组,为什么会这样？
谢谢!:)
