C＃序列化字典< ulong，ulong>到JSON [英] C# Serialize Dictionary<ulong,ulong> to JSON

问题描述

  new JavaScriptSerializer（）。Serialize（） mydict）`
  

键入'System.Collections.Generic.Dictionary`2 [[System.UInt64，mscorlib，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]，[System.Nullable`1 [[System.UInt64，mscorlib，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089 ]]，mscorlib，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]]'不支持字典的序列化/反序列化，键必须是字符串或对象。

有没有办法做到这一点？可能通过LINQ或者相对简单的方法将ulongs转换成字符串？

解决方案

  var dict = mapping.ToDictionary（item => item.Key.ToString（），item => item.Value.ToString（））;`
  

将任何字典< K，V> 转换为字典< string，string> 然后序列化工作。

I am trying to serialize a Dictionary to JSON, and get the following exception:

new JavaScriptSerializer().Serialize(mydict)`

Type 'System.Collections.Generic.Dictionary`2[[System.UInt64, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Nullable`1[[System.UInt64, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not supported for serialization/deserialization of a dictionary, keys must be strings or objects.

Is there an easy way to do this? Maybe converting the ulongs to strings via LINQ or something relatively terse?

解决方案

var dict = mapping.ToDictionary(item => item.Key.ToString(), item => item.Value.ToString());`

that will convert any Dictionary<K,V> to Dictionary<string,string> and serialization then works.
