本文介绍了一种使用 C# 的 Marshal 类将自定义结构体转换为字节数组的方法，并提供了序列化和反序列化的示例代码。

如何将自定义的structure转换为byte[]？

整理者：郑昀@UltraPower
示例如下：
using System.Runtime.InteropServices;

        public static byte[] RawSerialize( object anything )

        {

            int rawsize = Marshal.SizeOf( anything );

            IntPtr buffer = Marshal.AllocHGlobal( rawsize );

            Marshal.StructureToPtr( anything, buffer, false );

            byte[] rawdatas = new byte[ rawsize ];

            Marshal.Copy( buffer, rawdatas, 0, rawsize );

            Marshal.FreeHGlobal( buffer );

            return rawdatas;

        }

 

        public static object RawDeserialize( byte[] rawdatas, Type anytype )

        {

            int rawsize = Marshal.SizeOf( anytype );

            if( rawsize > rawdatas.Length )

                return null;

            IntPtr buffer = Marshal.AllocHGlobal( rawsize );

            Marshal.Copy( rawdatas, 0, buffer, rawsize );

            object retobj = Marshal.PtrToStructure( buffer, anytype );

            Marshal.FreeHGlobal( buffer );

            return retobj;

                 }
 

        // sample usage:

        [StructLayout(LayoutKind.Sequential, Pack=1, CharSet=CharSet.Ansi)]

            struct YourStruct

        {

            public Int32  First;

            public Int32  Second;

            [MarshalAs( UnmanagedType.ByValTStr, SizeConst=16 )]

            public String Text;

        }

 

        YourStruct st;

        st.First  = 11;

        st.Second = 22;

        st.Text = "Hello";

        byte[] rd = RawSerialize( st );

        // reverse:

        YourStruct rst = (YourStruct) RawDeserialize( rd, typeof(YourStruct));

Emgu CV 是 OpenCV 的 .NET 包装器，可以让开发者在 .NET 语言（如 C#）中使用 OpenCV 的功能进行图像处理。在进行图像处理时，Emgu CV 提供了丰富的 API 可以使用。PictureBoxImageBox下面是一个详细的示例，演示如何使用 Emgu CV 在 C# 中进行基本的图像处理，包括加载图像、转换为灰度图像、进行边缘检测，然后显示结果。byte在这个示例中，我们使用了三个PictureBox控件来显示原始图像、灰度图像和边缘检测后的图像。

在Socket编程中经常会碰到将Struct转换为byte数组进行传送的情况. 如果服务器和客户端都是自己开发的话, 用序列化和反序列化当然会比较简单, 但序列化后会数据里会包含一些额外的数据，如：程序集名称、版本、公钥等, 不适用于一端是非托管程序. 在.NET Framework的System.Runtime.InteropServices.Marshal类中包含两个方法可以解决此问题: S

当想到所有文件都转换为 XML时，确实是一件好事。但是，这并非事实。仍旧还有大量的文件格式不是XML，甚至也不是ASCII。二进制文件仍然在网络中传播，储存在磁盘上，在应用程序之间传递。相比之下，在处理这些问题方面，它们比文本文件显得更有效率些。在 C 和 C++ 中，读取二进制文件还是很容易的。除了一些开始符（carriage return）和结束符（line feed）的问题，每一个读到C

背景： 之前项目使用HttpWebRequest请求接口，获取返回的流，并将流转换成byte[]然后失败了。又尝试将其转换成MemoryStream，结果又失败了。最后一查看返回Stream的类型才发现了原因… C# 中获取Http请求的方法相信大家也都知道，这里我只写出关键的两句： //创建请求 HttpWebRequest webRequest = (HttpWebReque...
C#中实现byte[]与任意对象互换(服务端通讯专用)

C++中，我们可以非常方便的将网络通讯接收来的char*缓冲区转成任意类型的结构体，并从中提取必要信息，只需要一个结构体类型指针的强制转换即可。 但是在C#中，所有涉及到内存及指针的操作均被判定为不安全操作，使得上述机制的实现变得复杂化。 要在C#中便捷的实现网络通讯缓冲区byte[]与任意类型对象的相互转换，常用的方法大致有三： 1.序列化与反序列化 public sta
Marshal类 两个方法StructureToPtr和PtrToStructure实现序列化 字节 数组 转换

我们主要是使用Marshal类里的两个方法： 第一个是StructureToPtr，将数据从托管对象封送到非托管内存块。 第二个是PtrToStructure，将数据从非托管内存块封送到新分配的指定类型的托管对象。 只要有了这两个相互转换的方法，我们就可以实现序列化了。 首先我们先来看下序列化 序列化： 有一个前提条件，那就是我们必须要知道需要序列化对象的大小。 第一步：我们先求出对
