C# 验证视图模型在api中是否仅通过fluent api传递一次

我正在使用Fluent API验证API中的有效负载。Street Address/MailingAddress/Lockbox Address是域模型中的三个不同属性。我想在验证中确保街道地址和邮寄地址只传递一次

正确有效载荷

{
"id" :123,
"name":"test",
"streetAddress": {
"city":"London",
"address":"q23"
},
"MailingAddress": {
"city":"NewYork",
"address":"q2453"
},
"LockBoxAddress": {
"city":"Miami",
"address":"q23888"
}
}

{
"id" :123,
"name":"test",
"streetAddress": {
"city":"London",
"address":"q23"
},
"streetAddress": {
"city":"NewYork",
"address":"q2453"
}
}

域模型

public string id{get;set;}
public string name{get;set;}
public Address streetAddress{get;set;}
public Address MailingAddress{get;set;}
public Address LockboxAddress{get;set;}

不正确的有效载荷

{
"id" :123,
"name":"test",
"streetAddress": {
"city":"London",
"address":"q23"
},
"MailingAddress": {
"city":"NewYork",
"address":"q2453"
},
"LockBoxAddress": {
"city":"Miami",
"address":"q23888"
}
}

{
"id" :123,
"name":"test",
"streetAddress": {
"city":"London",
"address":"q23"
},
"streetAddress": {
"city":"NewYork",
"address":"q2453"
}
}

我希望上面的有效载荷错误地指出，您不能传递多个街道地址，我使用的是Fluent API

RuleFor(x => x.streetAddress).Count(x =>x < 2).When(x => x.streetAddress!= null); 

Fluent API

RuleFor(x => x.streetAddress).Count(x =>x < 2).When(x => x.streetAddress!= null); 

RuleFor（x=>x.streetAddress）.Count（x=>x<2）.When（x=>x.streetAddress！=null）；

没有属性可获取模型的计数。有什么想法吗

您无法通过Fluent验证API进行验证。因为在有效负载反序列化之后，域模型中只有一个

streetAddress

属性。另一方面，您的代码

RuleFor（x=>x.streetAddress）

返回

irulebuilderininitial

而不是

irulebuilderininitial。首先，为什么JSON字符串/对象中会有重复的键？请参阅您使用的是asp.net-core还是asp.net？@Jota.Toledo.net core
