在c＃中序列化字典 [英] Serialize Dictionary in c#

问题描述

我有词典

词典< string，List< string>> Dic =  new 字典<字符串，List<字符串>>（）; 

如何使用此序列化class？



序列化等级

 [XmlRoot（  Dictionary）] 
  public   class  SerializableDictionary< TKey，TValue> ：Dictionary< TKey，TValue>，IXmlSerializable 
 {
   #region IXmlSerializable Members 
   public  System.Xml.Schema.XmlSchema GetSchema（）
 {
  return  空; 
} 
  public   void  ReadXml（System.Xml.XmlReader reader）
 {
 XmlSerializer keySerializer =  new  XmlSerializer（ typeof （TKey））; 
 XmlSerializer valueSerializer =  new  XmlSerializer（ typeof （TValue））; 
  bool  wasEmpty = reader.IsEmptyElement; 
 reader.Read（）; 
  if （wasEmpty）
  return ; 
  while （reader.NodeType！= System.Xml.XmlNodeType.EndElement）
 {
 reader.ReadStartElement（  item）; 
 reader.ReadStartElement（  key）; 
 TKey key =（TKey）keySerializer.Deserialize（reader）; 
 reader.ReadEndElement（）; 
 reader.ReadStartElement（  value）; 
 TValue  value  =（TValue）valueSerializer.Deserialize（reader）; 
 reader.ReadEndElement（）; 
 此 .Add（key， value ）; 
 reader.ReadEndElement（）; 
 reader.MoveToContent（）; 
} 
 reader.ReadEndElement（）; 
} 
  public   void  WriteXml（System.Xml.XmlWriter writer）
 {
 XmlSerializer keySerializer =  new  XmlSerializer（ typeof （TKey））; 
 XmlSerializer valueSerializer =  new  XmlSerializer（ typeof （TValue））; 
  foreach （TKey key  in   this  .Keys）
 {
 writer.WriteStartElement（  item） ; 
 writer.WriteStartElement（  key）; 
 keySerializer.Serialize（writer，key）; 
 writer.WriteEndElement（）; 
 writer.WriteStartElement（  value）; 
 TValue  value  = 此 [key]; 
 valueSerializer.Serialize（writer， value ）; 
 writer.WriteEndElement（）; 
 writer.WriteEndElement（）; 
} 
} 
   #endregion 
 } 
 

解决方案

只需使用您的类

 SerializableDictionary< string，List< string>> 

而不是

字典<字符串，列表<字符串>> 

样本：

< pre lang =c＃> SerializableDictionary< string，List< string>> b = new SerializableDictionary< string，List< string>>（）;
List< string> stringList = new List< string>（）;
stringList.Add（ 1）;
b.Add（ One，stringList）;

XmlSerializer serializer = new XmlSerializer（ typeof （SerializableDictionary< string，List<串GT;>））;
TextWriter textWriter = new StreamWriter（ @ dictionarySerialized.xml）;
serializer.Serialize（textWriter，b）;
textWriter.Close（）;

尝试通过BinaryFormatter进行序列化

这是代码

  private   void 反序列化（）
 {
 尝试 
 {
  var  f_fileStream = File.OpenRead（ @  dictionarySerialized.xml）; 
  var  f_binaryFormatter =  new  System.Runtime.Serialization.Formatters.Binary.BinaryFormatter（）; 
 myDictionary =（字典<字符串，> ）f_binaryFormatter.Deserialize（f_fileStream）; 
 f_fileStream.Close（）; 
} 
  catch （例外情况）
 {
; 
} 
} 
 私有  void  Serialize（）
 {
 尝试 
 {
  var  f_fileStream =  new  FileStream（ @  dictionarySerialized.xml，FileMode .Create，FileAccess.Write）; 
  var  f_binaryFormatter =  new  System.Runtime.Serialization.Formatters.Binary.BinaryFormatter（）; 
 f_binaryFormatter.Serialize（f_fileStream，myDictionary）; 
 f_fileStream.Close（）; 
} 
  catch （例外情况）
 {
; 
} 
} 

I have Dictionary

Dictionary<string, List<string>> Dic = new Dictionary<string, List<string>>();

How serialize it with this class ?

Class for Serialization

[XmlRoot("Dictionary")]
   public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable
   {
       #region IXmlSerializable Members
       public System.Xml.Schema.XmlSchema GetSchema()
       {
           return null;
       }
       public void ReadXml(System.Xml.XmlReader reader)
       {
           XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
           XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));
           bool wasEmpty = reader.IsEmptyElement;
           reader.Read();
           if (wasEmpty)
               return;
           while (reader.NodeType != System.Xml.XmlNodeType.EndElement)
           {
               reader.ReadStartElement("item");
               reader.ReadStartElement("key");
               TKey key = (TKey)keySerializer.Deserialize(reader);
               reader.ReadEndElement();
               reader.ReadStartElement("value");
               TValue value = (TValue)valueSerializer.Deserialize(reader);
               reader.ReadEndElement();
               this.Add(key, value);
               reader.ReadEndElement();
               reader.MoveToContent();
           }
           reader.ReadEndElement();
       }
       public void WriteXml(System.Xml.XmlWriter writer)
       {
           XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
           XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));
           foreach (TKey key in this.Keys)
           {
               writer.WriteStartElement("item");
               writer.WriteStartElement("key");
               keySerializer.Serialize(writer, key);
               writer.WriteEndElement();
               writer.WriteStartElement("value");
               TValue value = this[key];
               valueSerializer.Serialize(writer, value);
               writer.WriteEndElement();
               writer.WriteEndElement();
           }
       }
       #endregion
   }

解决方案

Just use your class

SerializableDictionary<string, List<string>>

instead of

Dictionary<string, List<string>>

Sample:

SerializableDictionary<string, List<string>> b = new SerializableDictionary<string, List<string>>();            
List<string> stringList = new List<string>();
stringList.Add("1");
b.Add("One", stringList);
                       
XmlSerializer serializer = new XmlSerializer(typeof(SerializableDictionary<string, List<string>>));
TextWriter textWriter = new StreamWriter(@"dictionarySerialized.xml");
serializer.Serialize(textWriter, b);
textWriter.Close();

Try Serializating through BinaryFormatter
Here is code

private void Deserialize()
        {
            try
            {
                var f_fileStream = File.OpenRead(@"dictionarySerialized.xml");
                var f_binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
                myDictionary = (Dictionary<string,>)f_binaryFormatter.Deserialize(f_fileStream);
                f_fileStream.Close();
            }
            catch (Exception ex)
            {
                ;
            }
        }
        private void Serialize()
        {
            try
            {
                var f_fileStream = new FileStream(@"dictionarySerialized.xml", FileMode.Create, FileAccess.Write);
                var f_binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
                f_binaryFormatter.Serialize(f_fileStream, myDictionary);
                f_fileStream.Close();
            }
            catch (Exception ex)
            {
                ;
            }
        }
