如何使用gzip压缩.net对象实例 [英] How to compress a .net object instance using gzip

问题描述

我想在将数据库的QUERYS的结果添加到缓存之前压缩它们。

I am wanting to compress results from QUERYS of the database before adding them to the cache.

我想要能够压缩任何引用类型。

I want to be able to compress any reference type.

我有一个压缩字符串的工作版本。基于scott hanselman的博客的想法 http://shrinkster.com/173t

I have a working version of this for compressing strings.. the idea based on scott hanselman 's blog post http://shrinkster.com/173t

压缩.net对象的任何想法？

any ideas for compressing a .net object?

我知道它将是只读缓存，因为缓存中的对象只是字节数组。

I know that it will be a read only cache since the objects in the cache will just be byte arrays..

推荐答案

这不适用于任何引用类型。这将适用于可序列化类型。将 BinaryFormatter 链接到通过管道传输到文件的压缩流：

This won't work for any reference type. This will work for Serializable types. Hook up a BinaryFormatter to a compression stream which is piped to a file:

var formatter = new BinaryFormatter();
using (var outputFile = new FileStream("OutputFile", FileMode.CreateNew))
using (var compressionStream = new GZipStream(
                         outputFile, CompressionMode.Compress)) {
   formatter.Serialize(compressionStream, objToSerialize);
   compressionStream.Flush();
}

您可以使用 MemoryStream 将内容保存在内存中，而不是写入文件。我怀疑这是真正的缓存的有效解决方案，但是。

You could use a MemoryStream to hold the contents in memory, rather than writing to a file. I doubt this is really an effective solution for a cache, however.
