爲什麼在控制器方法中將具體對象設置爲null？

Question

當我將請求發送到我的控制器，由於某種原因，將其分配給對象的所有空值：

我發送請求如下：

{ 
    "createCustomerPaymentProfileRequest": { 
     "merchantAuthentication": { 
    "name": "3efsw3sd66", 
    "transactionKey": "7m444433G" 
    }, 
    "customerProfileId": "10000", 
    "paymentProfile": { 
     "billTo": { 
     "firstName": "John", 
     "lastName": "Doe", 
     "address": "123 Main St.", 
     "city": "Bellevue", 
     "state": "WA", 
     "zip": "98004", 
     "country": "USA", 
     "phoneNumber": "000-000-0000" 
     }, 
     "payment": { 
     "creditCard": { 
      "cardNumber": "4111111111111111", 
      "expirationDate": "2023-12" 
     } 
     }, 
     "defaultPaymentProfile": false 
    }, 
    "validationMode": "liveMode" 
    } 
} 

這是我如何從發行郵遞員請求：

爲什麼我的請求的屬性設置爲null？

/// <remarks/> 
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] 
[System.SerializableAttribute()] 
[System.Diagnostics.DebuggerStepThroughAttribute()] 
[System.ComponentModel.DesignerCategoryAttribute("code")] 
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="AnetApi/xml/v1/schema/AnetApiSchema.xsd")] 
[System.Xml.Serialization.XmlRootAttribute(Namespace="AnetApi/xml/v1/schema/AnetApiSchema.xsd", IsNullable=false)] 
public partial class createCustomerPaymentProfileRequest : ANetApiRequest { 

    /// <remarks/> 
    public string customerProfileId; 

    /// <remarks/> 
    public customerPaymentProfileType paymentProfile; 

    /// <remarks/> 
    public validationModeEnum validationMode; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlIgnoreAttribute()] 
    public bool validationModeSpecified; 
} 

其母公司被定義爲：

作爲類被定義

/// <remarks/> 
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] 
[System.SerializableAttribute()] 
[System.Diagnostics.DebuggerStepThroughAttribute()] 
[System.ComponentModel.DesignerCategoryAttribute("code")] 
[System.Xml.Serialization.XmlTypeAttribute(Namespace="AnetApi/xml/v1/schema/AnetApiSchema.xsd")] 
public partial class ANetApiRequest { 

    /// <remarks/> 
    public merchantAuthenticationType merchantAuthentication; 

    /// <remarks/> 
    public string clientId; 

    /// <remarks/> 
    public string refId; 
} 

而屬性中的一個被定義爲：

/// <remarks/> 
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] 
[System.SerializableAttribute()] 
[System.Diagnostics.DebuggerStepThroughAttribute()] 
[System.ComponentModel.DesignerCategoryAttribute("code")] 
[System.Xml.Serialization.XmlTypeAttribute(Namespace="AnetApi/xml/v1/schema/AnetApiSchema.xsd")] 
public partial class merchantAuthenticationType { 

    /// <remarks/> 
    public string name; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlElementAttribute("accessToken", typeof(string))] 
    [System.Xml.Serialization.XmlElementAttribute("clientKey", typeof(string))] 
    [System.Xml.Serialization.XmlElementAttribute("fingerPrint", typeof(fingerPrintType))] 
    [System.Xml.Serialization.XmlElementAttribute("impersonationAuthentication", typeof(impersonationAuthenticationType))] 
    [System.Xml.Serialization.XmlElementAttribute("password", typeof(string))] 
    [System.Xml.Serialization.XmlElementAttribute("sessionToken", typeof(string))] 
    [System.Xml.Serialization.XmlElementAttribute("transactionKey", typeof(string))] 
    [System.Xml.Serialization.XmlChoiceIdentifierAttribute("ItemElementName")] 
    public object Item; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlIgnoreAttribute()] 
    public ItemChoiceType ItemElementName; 

    /// <remarks/> 
    public string mobileDeviceId; 
} 

和另一個：

public partial class customerPaymentProfileType : customerPaymentProfileBaseType { 

    /// <remarks/> 
    public paymentType payment; 

    /// <remarks/> 
    public driversLicenseType driversLicense; 

    /// <remarks/> 
    public string taxId; 

    /// <remarks/> 
    public bool defaultPaymentProfile; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlIgnoreAttribute()] 
    public bool defaultPaymentProfileSpecified; 
} 

Answer 1

發送的json是一個級別太深。

有效載荷應

{ 
    "merchantAuthentication": { 
     "name": "3efsw3sd66", 
     "transactionKey": "7m444433G" 
    }, 
    "customerProfileId": "10000", 
    "paymentProfile": { 
     "billTo": { 
     "firstName": "John", 
     "lastName": "Doe", 
     "address": "123 Main St.", 
     "city": "Bellevue", 
     "state": "WA", 
     "zip": "98004", 
     "country": "USA", 
     "phoneNumber": "000-000-0000" 
     }, 
     "payment": { 
     "creditCard": { 
      "cardNumber": "4111111111111111", 
      "expirationDate": "2023-12" 
     } 
     }, 
     "defaultPaymentProfile": false 
    }, 
    "validationMode": "liveMode" 
    } 

否則爲了配合你那裏的JSON模式將不得不像這樣

public class Example { 
    public createCustomerPaymentProfileRequest createCustomerPaymentProfileRequest { get; set; } 
}
