是否可以使用 DataContractJsonSerializer将.Net Dictionary < Key,Value > 序列化为 JSON,其格式如下:
{
key0:value0,
key1:value1,
...
}
我使用 Dictionary < K,V > ,因为没有预定义的输入结构。
我只对 DataContractJsonSerializer的结果感兴趣!我已经找到了一个“替代”示例,但是在输出中有一个额外的“数据”,如果字典 < K,String > 是,那么转义也是假的。
我已经找到了解决方案,多么需要! 首先,一个可序列化的“ dictionary”类: (当然,这个示例只以一种方式工作,但是我不需要反序列化)
[Serializable]
public class MyJsonDictionary<K, V> : ISerializable {
Dictionary<K, V> dict = new Dictionary<K, V>();
public MyJsonDictionary() { }
protected MyJsonDictionary( SerializationInfo info, StreamingContext context ) {
throw new NotImplementedException();
}
public void GetObjectData( SerializationInfo info, StreamingContext context ) {
foreach( K key in dict.Keys ) {
info.AddValue( key.ToString(), dict[ key ] );
}
}
public void Add( K key, V value ) {
dict.Add( key, value );
}
public V this[ K index ] {
set { dict[ index ] = value; }
get { return dict[ index ]; }
}
}
用法:
public class MainClass {
public static String Serialize( Object data ) {
var serializer = new DataContractJsonSerializer( data.GetType() );
var ms = new MemoryStream();
serializer.WriteObject( ms, data );
return Encoding.UTF8.GetString( ms.ToArray() );
}
public static void Main() {
MyJsonDictionary<String, Object> result = new MyJsonDictionary<String, Object>();
result["foo"] = "bar";
result["Name"] = "John Doe";
result["Age"] = 32;
MyJsonDictionary<String, Object> address = new MyJsonDictionary<String, Object>();
result["Address"] = address;
address["Street"] = "30 Rockefeller Plaza";
address["City"] = "New York City";
address["State"] = "NY";
Console.WriteLine( Serialize( result ) );
Console.ReadLine();
}
}
结果就是:
{
"foo":"bar",
"Name":"John Doe",
"Age":32,
"Address":{
"__type":"MyJsonDictionaryOfstringanyType:#Json_Dictionary_Test",
"Street":"30 Rockefeller Plaza",
"City":"New York City",
"State":"NY"
}
}
