.NET WebAPI 序列化 k_BackingField 脏 [英] .NET WebAPI Serialization k_BackingField Nastiness

问题描述

当我序列化以下内容时:

When i serialize the following:

[Serializable]
public class Error
{

    public string Status { get; set; }
    public string Message { get; set; }
    public string ErrorReferenceCode { get; set; }
    public List<FriendlyError> Errors { get; set; }
}

我得到了这令人作呕的烂摊子:

I get this disgusting mess:

<ErrorRootOfstring xmlns:i="http://www.w3.org/2001/XMLSchema-instance"   xmlns="http://schemas.datacontract.org/2004/07/Printmee.Api">
<_x003C_Errors_x003E_k__BackingField>
An exception has occurred. Please contact printmee support
</_x003C_Errors_x003E_k__BackingField>
<_x003C_LookupCode_x003E_k__BackingField>988232ec-6bc9-48f3-8116-7ff7c71302dd</_x003C_LookupCode_x003E_k__BackingField>
</ErrorRootOfstring>

什么给?我怎样才能让它漂亮?JSON 响应还包含 k_BackingField

What gives? How can i make this pretty? JSON responses also contain the k_BackingField

推荐答案

默认情况下你不需要使用 [Serializable] 和 [DataContract] 来工作使用 Web API.

By default you don't need to use neither [Serializable] nor [DataContract] to work with Web API.

让您的模型保持原样，Web API 会为您序列化所有公共属性.

Just leave your model as is, and Web API would serialize all the public properties for you.

只有当您想对包含的内容有更多的控制时，您才可以使用 [DataContract] 和要包含在 [DataMember] 中的属性来装饰您的类(因为DCS 和 JSON.NET 都尊重这些属性).

Only if you want to have more control about what's included, you then decorate your class with [DataContract] and the properties to be included with [DataMember] (because both DCS and JSON.NET respsect these attributes).

如果由于某种原因，您的类需要 [Serializable](即您出于某种原因将其序列化为内存流，进行深度复制等)，那么您必须同时使用两者属性结合以防止支持字段名称:

If for some reason, you need the [Serializable] on your class (i.e. you are serializing it into a memory stream for some reason, doing deep copies etc), then you have to use both attributes in conjunction to prevent the backing field names:

[Serializable]
[DataContract]
public class Error
{
    [DataMember]
    public string Status { get; set; }
    [DataMember]
    public string Message { get; set; }
    [DataMember]
    public string ErrorReferenceCode { get; set; }
    [DataMember]
    public List<FriendlyError> Errors { get; set; }
}
