本文介绍了一种使用C#实现的对象压缩与文件存取的方法。通过BinaryFormatter序列化对象为字节数组，再利用DeflateStream进行压缩，最后将压缩后的数据保存到指定路径的文件中。同时提供了从文件读取并解压还原对象的功能。

public static void SaveByteData(string path,object data)

{

FileStream fs = null;

try

{

fs = new FileStream(path, FileMode.OpenOrCreate);

if (fs != null)

{

var bytes = ZipObject.CompressionObject(data);

fs.Write(bytes, 0, bytes.Count());

}

catch

{

}

finally

{

fs.Close();

}

public static object LoadByteData(string path)

{

FileStream fs = null;

object result = null;

try

{

fs = new FileStream(path, FileMode.Open);

if (fs != null)

{

int length = (int)fs.Length;

byte[] bytes = new byte[length];

fs.Read(bytes, 0, length);

result = ZipObject.DecompressionObject(bytes);

}

catch

{

}

finally

{

fs.Close();

}

return result;

}
