C# 将词典序列化<；字符串，对象>；其中包含一个列表<；字符串>；？

我发现了一个可序列化的字典，它运行得非常好：

但是每当字典中的一个对象只是一个字符串列表时，我就会遇到一个例外。NET告诉我它无法序列化它：

Serialize 'C:\bin\Debug\Settings\Default.xml' : System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: The type System.Collections.Generic.List`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] may not be used in this context.

这可能吗？我想要这个功能，并假设您可以嵌套这样的对象。如果这是不可能的，有没有一种方法可以将字典写入磁盘（不必是XML），然后重新加载它，而不必为此编写自定义包装？我最初是一名mac开发人员，这种序列化非常简单，所以我可能在.NET上遗漏了一些东西

编辑：尝试奥德赛的例子时，我得到：

System.Runtime.Serialization.SerializationException: Type 'System.Collections.Generic.List`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' with data contract name 'ArrayOfstring:http://schemas.microsoft.com/2003/10/Serialization/Arrays' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.

---

另一种选择是，使用

System.Runtime.Serialization.DataContractSerializer

可能会更幸运。例如：

Dictionary<string, List<string>> dict = new Dictionary<string, List<string>>();
dict.Add("test", new List<string>() { "t", "b" });

StringBuilder xmlString = new StringBuilder();
using (XmlWriter writer = XmlWriter.Create(xmlString))
{
    DataContractSerializer serializer = new DataContractSerializer(typeof(Dictionary<string, List<string>>));
    serializer.WriteObject(writer, dict);
}

Dictionary dict=new Dictionary（）；
dict.Add（“test”，new List（）{“t”，“b”}）；
StringBuilder xmlString=新的StringBuilder（）；
使用（XmlWriter=XmlWriter.Create（xmlString））
{
DataContractSerializer serializer=新的DataContractSerializer（typeof（Dictionary））；
serializer.WriteObject（writer，dict）；
}

这将产生：

<?xml version="1.0" encoding="utf-16"?><ArrayOfKeyValueOfstringArrayOfstringty7Ep6D1 xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays"><KeyValueOfstringArrayOfstringty7Ep6D1><Key>test</Key><Value><string>t</string><string>b</string></Value></KeyValueOfstringArrayOfstringty7Ep6D1></ArrayOfKeyValueOfstringArrayOfstringty7Ep6D1>

我在序列化通用列表时也遇到过类似的问题。尝试在序列化之前将列表更改为字符串数组

string[]

，然后在反序列化之后返回到

列表。这很容易做到，可能会解决您的问题：

//List<string> to string[]
string[] sArray = sList.ToArray();

//string[] to List<string>
List<string> sList = sArray.ToList();

//列表到字符串[]
字符串[]sArray=sList.ToArray（）；
//要列出的字符串[]
List sList=sArray.ToList（）；
您是如何获得字符串的？@Geesu您的意思是，您是如何反序列化它的？否您是如何粘贴它生成的内容的？我正试图这样打印到控制台：长度始终为0
xmlString.ToString（）
，使用
-子句在
之外执行，或者调用
writer.Flush（）
，以确保编写器在读取字符串之前刷新。是的，我在内部执行，这就是问题所在。奇怪的是，它适用于您的示例，但适用于包含我正在获取的数据的dict：另一个异常（请参见上面的编辑）
