如何COM preSS使用gzip .NET对象实例 [英] How to compress a .net object instance using gzip

问题描述

我想从数据库的QUERYS玉米preSS结果将它们添加到缓存之前

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

我希望能够到COM preSS任何引用类型。

I want to be able to compress any reference type.

我有这样的COM pressing串一个工作版本。基于在Scott Hanselman的博客文章 HTTP：// shrinkster .COM /173吨

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

任何想法COM pressing .NET对象？

any ideas for compressing a .net object?

我知道，这将是一个只读缓存，因为在缓存中的对象只会是字节数组。

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

这不会对任何引用类型的工作。这适用于序列化类型。钩了的BinaryFormatter 到被输送到一个文件，一个COM pression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();
}

您可以使用的MemoryStream 持有的内容在内存中，而不是写入文件。我怀疑这是真正的高速缓存有效的解决方案，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.
