Newtonsoft.Json导致序列化发生两次，导致Reference.cs中出现重复定义

Question

我有一个项目Common，它有一个服务引用。 将Newtonsoft.json(Version 6.0.2的引用添加到具有服务引用的同一项目（Common）和Serializable类ChatLine

之后

[Serializable]
public class ChatLine
{
    [JsonProperty("L")]
    public string LineId { get; set; }

    [JsonProperty("CT")]
    public DateTime ConversationTimeInUtc { get; set; }

    [JsonProperty("S")]
    public string SenderId { get; set; }

    [JsonProperty("R")]
    public IEnumerable<string> Recipients { get; set; }

    [JsonProperty("CM")]
    public string ConversationMessage { get; set; }
}

我更新了服务参考。现在建设项目Common时， 弹出以下错误。

构建错误：

  

错误5命名空间''已经包含了一个定义   'AuditStatus'

这是更新服务参考

后在Reference.cs中生成的代码

[DataContract]
public enum AuditStatus : byte
{
    [EnumMember]
    Both,
    [EnumMember]
    IsAudited,
    [EnumMember]
    IsNotAudited,
}

// After updating reference, two definitions for above data contract is generated.
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34234")]
[System.SerializableAttribute()]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://schemas.datacontract.org/2004/07/Presensoft.Server.Platform.DataContracts")]
public enum AuditStatus {

    /// <remarks/>
    Both,

    /// <remarks/>
    IsAudited,

    /// <remarks/>
    IsNotAudited,
}     

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")]
[System.Runtime.Serialization.DataContractAttribute(Name="AuditStatus", Namespace="http://schemas.datacontract.org/2004/07/Presensoft.Server.Platform.DataContracts")]
public enum AuditStatus : byte {

    [System.Runtime.Serialization.EnumMemberAttribute()]
    Both = 0,

    [System.Runtime.Serialization.EnumMemberAttribute()]
    IsAudited = 1,

    [System.Runtime.Serialization.EnumMemberAttribute()]
    IsNotAudited = 2,
}

注意：我注意到的是添加对Newtonsoft.Json的引用导致序列化发生在两个不同的序列化器上：XML serailizer和Datacontract serailizer导致Reference.cs中出现重复定义。如果我删除对Newtonsoft.Json的引用并将ChatLine类更改为所有内容正常工作。

[Serializable]
public class ChatLine
{
    public string LineId { get; set; }

    public DateTime ConversationTimeInUtc { get; set; }

    public string SenderId { get; set; }

    public IEnumerable<string> Recipients { get; set; }

    public string ConversationMessage { get; set; }
}

知道这是什么问题吗？

Answer 1

您的项目中可能存在冲突的引用。在创建新的服务引用时，您可以告诉visual studio忽略您的程序集。尝试选择＆＃34;重复使用类型...＆＃34;并选择除自己的装配之外的所有东西。

Answer 2

尝试删除[Serailizable]属性，JSON.Net不需要。
