本文介绍了一种使用 .NET 中 BinaryFormatter 类进行图片序列化和反序列化的实现方法。该过程包括将 PictureBox 中的图片转换为字节数组，并从字节数组还原图片。文章提供了具体的 C# 代码示例。

using System.Runtime.Serialization.Formatters.Binary;

            BinaryFormatter formatter = new BinaryFormatter();
            System.IO.MemoryStream ImageStream = new System.IO.MemoryStream();
            formatter.Serialize(ImageStream,pictureBox1.Image);
            BinaryReader reader = new BinaryReader(ImageStream);
            byte[] mBytes = new byte[ImageStream.Length];
            reader.Read(mBytes,0,mBytes.Length);

=================================================

            BinaryFormatter formatter = new BinaryFormatter();
            Stream ImageStream = new System.IO.MemoryStream();
            formatter.Serialize(ImageStream,pictureBox1.Image);
            //BinaryReader reader = new BinaryReader(ImageStream);
            byte[] mBytes = new byte[ImageStream.Length];
            ImageStream.Position = 0;
            ImageStream.Read(mBytes, 0, (int)ImageStream.Length);
            ImageStream.Close();

            Stream wFileStream = new System.IO.MemoryStream();
            //BinaryWriter writer = new BinaryWriter(wFileStream);
            wFileStream.Write(mBytes,0,mBytes.Length);
            wFileStream.Position = 0;
            pictureBox2.Image = (Image)(formatter.Deserialize(wFileStream));
            //writer.Close();
            wFileStream.Close();
            //wFileStream.Close();
