反序列化字典时存在问题
原标题:Deserialization problem with Dictionary

当我尝试将字典序列化时,一切都正常。但在反序列化时,显示计数为0。但是,使用列表时它正常工作。当反序列化列表和字典时,究竟发生了什么?

问题回答

字典不太支持序列化。这是一个已知问题,困扰着许多程序员,因此,如果您在Google上搜索“ .NET字典序列化”,您将得到许多带有“如何”和解决方法。

如果你使用 .Net 3.5,你可以使用DataContractSerializer来序列化字典。它比BinaryFormatter或XmlSerializer更快。

using System.Runtime.Serialization;

var dict = new Dictionary<string, string>();
dict.Add("a","a");

DataContractSerializer dcs = new DataContractSerializer(dict.GetType());
MemoryStream byteStream = new MemoryStream();
dcs.WriteObject(byteStream, dict);
byteStream.Position = 0;

var dict2 = dcs.ReadObject(byteStream);
