Question

如果我尝试使用System.Runtime.Serialization.Json.DataContractJsonSerializer序列化以下ClassToSerialize类的对象

[DataContract,Serializable]
public class ClassToSerialize
{
    [NonSerialized] private bool _mf;
    public bool IsMf
    { 
        get { return _mf};
        set{ _mf = value;} 
    }

    [DataMember]
    public char PrimaryExc { get; set; }        
}

public class TestClass
{
    ClassToSerialize obj = new ClassToSerialize{PrimaryExchange = 'a', NoResults = true};
    var serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(ClassToSerialize);
    var ms = new MemoryStream();
    serializer.WriteObject(ms, obj);
    return Encoding.UTF8.GetString(ms.ToArray());
}

返回字符串仍包含IsMf属性及其值。 NOnSerialized属性被忽略。有人可以建议在使用DataContractJsonSerializer时使用什么属性，以便不序列化某些属性

以下代码对我有用（它几乎与您的代码相同，并修复了一些小的编译错误）：

using System;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.Text;

class Program
{
    static void Main()
    {
        var obj = new ClassToSerialize
        {
            PrimaryExc = 'a', 
            NoResults = true
        };

        var serializer 
            = new DataContractJsonSerializer(typeof(ClassToSerialize));

        var ms = new MemoryStream();

        serializer.WriteObject(ms, obj);

        Console.WriteLine(Encoding.UTF8.GetString(ms.ToArray()));
    }
}

[DataContract]
[Serializable]
public class ClassToSerialize
{
    [NonSerialized]
    private bool _mf;

    public bool IsMf
    {
        get { return _mf; }
        set { _mf = value; }
    }

    [DataMember]
    public bool NoResults { get; set; }

    [DataMember]
    public char PrimaryExc { get; set; }
}

<强>输出：

{"NoResults":true,"PrimaryExc":"a"}

不，它不包含它。你一定是弄错了：

[DataContract]
public class ClassToSerialize
{
    [NonSerialized] 
    private bool _mf;
    public bool IsMf
    {
        get { return _mf; }
        set{ _mf = value;}  
    }

    [DataMember]
    public char PrimaryExc { get; set; }        
}

class Program
{
    static void Main()
    {
        var obj = new ClassToSerialize 
        {
            PrimaryExc = 'a', 
            IsMf = false
        };
        var serializer = new DataContractJsonSerializer(obj.GetType());
        serializer.WriteObject(Console.OpenStandardOutput(), obj);
    }
}

输出：

{"PrimaryExc":"a"}

备注：您的班级不需要[Serializable]属性。这仅适用于binary serialization。

System.Runtime.Serialization.Json.DataContractJsonSerializer.WriteObject在序列化时忽略NonSerialized属性
