CodeGo.net>无法从Json反序列化获取对象数据
作者:互联网
我正在从Web服务器获取Json数据,但是当我尝试将其反序列化为对象时,却没有任何数据. Json字符串如下所示:
{"success":true,"data":[{"Id":6,"CustomerGuid":"70b390d8-82d5-4bba-aa68-fc8268a1b1ff","UserName":"victoria_victoria@nopCommerce.com","Email":"victoria_victoria@nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472393)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472393)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":5,"CustomerGuid":"eb9e6f24-f362-4c10-942a-366e2919dc11","UserName":"brenda_lindgren@nopCommerce.com","Email":"brenda_lindgren@nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472363)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472363)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":4,"CustomerGuid":"9f46dbae-6942-410c-90b8-9b38a0890064","UserName":"james_pan@nopCommerce.com","Email":"james_pan@nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472317)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472317)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":3,"CustomerGuid":"6277386b-13ee-427b-9cfe-4ebfa487c340","UserName":"arthur_holmes@nopCommerce.com","Email":"arthur_holmes@nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472253)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472253)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":2,"CustomerGuid":"241f45f1-b38c-4e22-8c5a-743fa3276620","UserName":"steve_gates@nopCommerce.com","Email":"steve_gates@nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472207)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472207)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":1,"CustomerGuid":"a940dc03-5f52-47d2-9391-8597b3b31cf2","UserName":"tony@lakesideos.com","Email":"tony@lakesideos.com","CustomerRoles":[{"Id":1,"Name":"Administrators","SystemName":"Administrators"},{"Id":2,"Name":"Forum Moderators","SystemName":"ForumModerators"},{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":true,"Active":true,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":"71.185.255.7","CreatedOnUtc":"\/Date(1472933470783)\/","LastLoginDateUtc":"\/Date(1477522483903)\/","LastActivityDateUtc":"\/Date(1477523996553)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[{"Id":1,"StoreId":1,"ShoppingCartTypeId":1,"CustomerId":1,"ProductId":18,"AttributesXml":null,"CustomerEnteredPrice":0.0000,"Quantity":1,"CreatedOnUtc":"\/Date(1473801903447)\/","UpdatedOnUtc":"\/Date(1473803336207)\/","IsFreeShipping":false,"IsShipEnabled":true,"AdditionalShippingCharge":0.0000,"IsTaxExempt":false}]}]}
我根据此链接中的建议创建了这些类:
recommendation
我用它来创建类:json2csharp
回应类别:
class Response
{
bool success;
IList<Customer> data;
}
客户类别:
class Customer
{
public int Id { get; set; }
public string CustomerGuid { get; set; }
public string UserName { get; set; }
public string Email { get; set; }
public List<CustomerRole> CustomerRoles { get; set; }
public object AdminComment { get; set; }
public bool IsTaxExempt { get; set; }
public int AffiliateId { get; set; }
public int VendorId { get; set; }
public bool HasShoppingCartItems { get; set; }
public bool Active { get; set; }
public bool Deleted { get; set; }
public bool IsSystemAccount { get; set; }
public object SystemName { get; set; }
public string LastIpAddress { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime? LastLoginDateUtc { get; set; }
public DateTime LastActivityDateUtc { get; set; }
public List<object> ExternalAuthenticationRecords { get; set; }
public List<object> ShoppingCartItems { get; set; }
}
CustomerRole类别:
class CustomerRole
{
public int Id { get; set; }
public string Name { get; set; }
public string SystemName { get; set; }
}
ExternalAuthenticationRecord类:
class ExternalAuthenticationRecord
{
public int Id { get; set; }
public int CustomerId { get; set; }
public string Email { get; set; }
public object ExternalIdentifier { get; set; }
public object ExternalDisplayIdentifier { get; set; }
public object OAuthToken { get; set; }
public object OAuthAccessToken { get; set; }
public string ProviderSystemName { get; set; }
}
ShoppingCartItem类:
class ShoppingCartItem
{
public int Id { get; set; }
public int StoreId { get; set; }
public int ShoppingCartTypeId { get; set; }
public int CustomerId { get; set; }
public int ProductId { get; set; }
public object AttributesXml { get; set; }
public double CustomerEnteredPrice { get; set; }
public int Quantity { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime UpdatedOnUtc { get; set; }
public bool IsFreeShipping { get; set; }
public bool IsShipEnabled { get; set; }
public double AdditionalShippingCharge { get; set; }
public bool IsTaxExempt { get; set; }
}
我正在使用以下语句反序列化Json字符串:Response res =(Response)JsonConvert.DeserializeObject(customerJson,(typeof(Response)));
当我在调试器中将其停止时,它将“ res”显示为数据:null和成功:false.
我没有任何错误.它只是不给我Json字符串中的数据.
任何人可以提供任何帮助以找出为什么我没有在“ res”中获取所需数据的帮助,将不胜感激.
谢谢,
托尼
解决方法:
该问题与Response类中的可访问性级别有关.默认情况下,字段,属性和方法是私有的,因此JsonConvert无法填充属性.
更改类,如下所示:
class Response
{
public bool success {get; set;}
public IList<Customer> data {get; set;}
}
它会起作用.
另一个改进与JsonConvert的使用有关.为了避免显式强制转换,请使用以下类型转换:JsonConvert.DeserializeObject< T>(string),其中T为Response
