BinaryFormatter的是否适用于任何COM pression？ [英] Does BinaryFormatter apply any compression?

问题描述

在.NET中的<一个href="http://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.binary.binaryformatter.aspx"><$c$c>BinaryFormatter使用对象图序列化，是任何类型的COM pression应用？

When .NET's BinaryFormatter is used to serialize an object graph, is any type of compression applied?

我问了我是否应该担心有很多重复的字符串和整数对象图的上下文。

I ask in the context of whether I should worry about the object graph having many repeated strings and integers.

修改 - 慢着，如果字符串被拘留在.NET中，有没有必要担心重复的字符串，正确

Edit - Hold on, if strings are interned in .NET, there's no need to worry about repeated strings, right?

推荐答案

没有，它不提供任何COM pression但你可以COM preSS输出使用的 GZipStream 键入

No, it doesn't provide any compression but you can compress the output yourself using the GZipStream type.

编辑： 迈赫达德有这个技术，他的回答到一个很好的例子<一href="http://stackoverflow.com/questions/964697/how-to-com$p$pss-a-net-object-instance-using-gzip">How对COM preSS .NET对象实例使用gzip 。

Mehrdad has a wonderful example of this technique in his answer to How to compress a .net object instance using gzip.

编辑2：字符串的可以的被拘留，但是，这并不意味着每一个字符串的是的实习。我不会就如何或为何CLR决定实习生字符串，因为这可以从版本改变（并修改）版本的任何假设。

Edit 2: Strings can be interned but that doesn't mean that every string is interned. I wouldn't make any assumptions on how or why the CLR decides to intern strings as this can change (and has changed) from version to version.
