json - 如何在asp.net web-api中接收带有间隔字段名称的Json？

Question

在我的 MVC-4 Web-API 服务器中，我收到一个名称中包含空格的 Json 字符串：

{ "field name" : "some value" , "simpleName" : "some string" }

我定义了一个Model类，例如：

public class SomeJsonModel
{
    [DataMember(Name = "field name")]
    public string FieldName { get; set; }

    public string SimpleName { get; set; }
}

现在SimpleName通过（尽管它的第一个字母大写不匹配，这很好），但FieldName变成null.

如何成功接收字段名称中有空格的 Json（预定义 - 我无法更改客户端数据源）？

Answer 1

Try adding [DataContract] on your class:

[DataContract]
public class SomeJsonModel
{
    [DataMember(Name = "field name")]
    public string FieldName { get; set; }

    [DataMember]
    public string SimpleName { get; set; }
}

Here is more info about this:

• on MSDN: "Apply the DataMemberAttribute attribute in conjunction with the DataContractAttribute to identify members of a type that are part of a data contract."
• a Json.NET issue relating to the DataMember's Name property being ignored. The resolution for that was to "Put DataContract on the class."
