具有自定义IEqualityComparer的Dictionary的XML序列化 [英] XML serialization of a Dictionary with a custom IEqualityComparer

问题描述

我想序列化一个具有自定义IEqualityComparer的Dictionary。

我尝试使用DataContractSerializer，但是我无法使Comparer被序列化。 p>

我不能使用BinaryFormatter，因为这个。

我总是可以这样做：

  var myDictionary = new MyDictionary（deserializedDictionary，myComparer）; 
  

但这意味着我需要两倍的字典使用的内存。

解决方案

我只是读错误报告...

二进制

大，你总是可能有一些问题。

你想尝试一个替代串行器吗？ protobuf-net是按照Google协议缓冲区格式定制的二进制序列化程序，可能适用于较大的集合，特别是组模式。

I want to serialize a Dictionary that has a custom IEqualityComparer.

I've tried using DataContractSerializer but I can't get the Comparer to be serialized.

I can't use BinaryFormatter because of this.

I can always do something like:

var myDictionary = new MyDictionary(deserializedDictionary, myComparer);

But that means I'd need twice the memory the dictionary uses.

解决方案

I just read the error report...

Binary serialization fails for object graphs with more than ~13.2 million objects.

if you have a graph that big, you always may have some problems.

Would you like to try an alternative serializer? "protobuf-net" is a bespoke binary serializer following Google's protocol buffers format, and may work for larger sets, especially in "group" mode.
