Json 反序列化对象返回空值 - 我做错了什么
本文关键字：错了 什么 空值 反序列化 对象 返回 Json | 更新日期: 2023-09-27 18:33:21
这是对DeserializeObject的调用：
listrootobject obj = JsonConvert.DeserializeObject<listrootobject>(json);
这是杰森.

这是 C# 类

public string Address1 { get; set; }
public string Address2 { get; set; }
public string Address3 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string PostalCode { get; set; }
}
public class EmailContact

public string PartyId { get; set; }
public string TypeName { get; set; }
public string EmailAddress { get; set; }
public string EmailOptOut { get; set; }
}
public class PhoneContact
{
public string PartyId { get; set; }
public string TypeName { get; set; }
public string CountryCode { get; set; }

使用 http://json2csharp.com/生成 C# 类并将其编写为从网站生成的类。最后，你解析根对象，如下所示。
但是您遇到了一个问题，因为它生成的属性名称在 C# 中无效，并且您无法使用这些名称创建 C# 类。但名称必须匹配才能反序列化。因此，您需要删除无效字符或重命名它们以满足 C# CLR 命名要求。然后创建格式正确的字符串的 C# 类。之后，您可以反序列化。
例如，我从原始字符串生成了 C# 对象，并且我的属性名称为
public SoMemberProfileDataSet __invalid_name__so:MemberProfileDataSet { get; set; }
这在 C# 中是无效的，但您需要将其在字符串中格式化为有效的东西，例如
public SoMemberProfileDataSet MemberProfileDataSet { get; set; }
通过重命名 JSON 字符串或从字符串中获取所需的属性，并在反序列化之前正确重新构造 JSON。
显示代码
例如，我在冒号之间组合了字符串并删除了 @ 符号，以便我创建了一个有效的 C# 对象。它去锯齿化。请参阅下面 json 字符串中的更改。因此，请格式化您的 json 字符串，您将拥有它。
string json = "{'"soMemberProfileDataSet'": {'"xmlnsmoso'": '"http://schema.socloud.com/1/MemberProfileDataSet.xsd'",'"Member'": {'"xmlns'": '"http://schema.socloud.com/1/MemberProfileDataSet.xsd'",'"PartyId'": '"63'",'"PartyTypeName'": '"Employee'",'"RoleId'": '"1310'",'"BusinessUnitCode'": '"95'",'"CardId'": null,'"PostalContact'": {'"PartyId'": '"63'",'"TypeName'": '"Mailing Address'",'"Address1'": '"100 Main Ave'",'"Address2'": null,'"Address3'": null,'"City'": '"Arlington'",'"State'": '"VA'",'"PostalCode'": '"22206'"},'"PhoneContact'": [{'"PartyId'": '"63'",'"TypeName'": '"Cell'",'"CountryCode'": '"1'",'"Telephone'": '"(555) 555-5555'",'"AdditionalData'": null,'"TextMessageOK'": '"false'"}, {'"PartyId'": '"63'",'"TypeName'": '"Home'",'"CountryCode'": '"1'",'"Telephone'": null,'"AdditionalData'": null,'"TextMessageOK'": '"false'"}],'"Property'": [{'"PartyId'": '"63'",'"Name'": '"First Name'",'"Value'": '"Katie'"}, {'"PartyId'": '"63'",'"Name'": '"Last Name'",'"Value'": '"Rodriguez'"}, {'"PartyId'": '"63'",'"Name'": '"Payroll ID'",'"Value'": null}, {'"PartyId'": '"63'",'"Name'": '"Lookup Initials'",'"Value'": null}, {'"PartyId'": '"63'",'"Name'": '"Date of Birth'",'"Value'": null}, {'"PartyId'": '"63'",'"Name'": '"Hire Date'",'"Value'": null}, {'"PartyId'": '"63'",'"Name'": '"Termination Date'",'"Value'": null}, {'"PartyId'": '"63'",'"Name'": '"Gender'",'"Value'": null}]}}}";
var listrootobject = JsonConvert.DeserializeObject<RootObject>(json);
您的类现在应如下所示，格式化后不再有无效的属性名称
public class PostalContact

public string PartyId { get; set; }
public string TypeName { get; set; }
public string Address1 { get; set; }
public object Address2 { get; set; }
