大家好,你能帮助我吗?我有以下课程
public class EmpTraining
{
public int CodColig { get; set; }
public string EmpID { get; set; }
public string Employee { get; set; }
public string CostCenter { get; set; }
public string Department { get; set; }
public string WorkstationID { get; set; }
public string Workstation { get; set; }
public string Training { get; set; }
public string CreateDt { get; set; }
public string DueDt { get; set; }
}
我需要对下面的json进行反序列化。
{
"EmployeesTrainings": [
{
"CODCOLIGADA": 1,
"CHAPA": "sample string 2",
"NOME": "sample string 3",
"CCUSTO": "sample string 4",
"Departamento": "sample string 5",
"CODPOSTO": "sample string 6",
"POSTO": "sample string 7",
"TREINAMENTO": "sample string 8",
"REALIZADO_EM": "2016-04-19T14:17:19.7291778-03:00",
"VALIDADE": "2016-04-19T14:17:19.7291778-03:00"
},
{
"CODCOLIGADA": 1,
"CHAPA": "sample string 2",
"NOME": "sample string 3",
"CCUSTO": "sample string 4",
"Departamento": "sample string 5",
"CODPOSTO": "sample string 6",
"POSTO": "sample string 7",
"TREINAMENTO": "sample string 8",
"REALIZADO_EM": "2016-04-19T14:17:19.7291778-03:00",
"VALIDADE": "2016-04-19T14:17:19.7291778-03:00"
}
],
"HasErrors": true,
"Errors": [
"sample string 1",
"sample string 2"
]
}
甚至更改错误发生的变量名称
无法反序列化当前的JSON对象(例如{“name”:“value”}) 进入类型 'System.Collections.Generic.List`1 [Foxconn.Portal.Model.HR.Training.EmpTraining]' 因为该类型需要一个JSON数组(例如[1,2,3])来反序列化 正确。
要修复此错误,请将JSON更改为JSON数组(例如 [1,2,3])或更改反序列化类型,使其成为正常的.NET type(例如,不是像整数这样的基本类型,不是集合类型 像数组或List一样,可以从JSON对象反序列化。 JsonObjectAttribute也可以添加到类型中以强制它 从JSON对象反序列化。
路径'EmployeesTrainings',第1行,第22位。
调用类反序列化的代码是:
public static List<EmpTraining> List(int codColig, string empID, string trainingID, string workstationID, string status, int? days)
{
List<EmpTraining> empList = Api.PostWebApiStr<List<EmpTraining>>(JSON, webApi, Token, timeOut);
if (empList.Count > 0)
return empList;
return new List<EmpTraining>();
}
我用来反序列化的类是下面的那个。
public static T PostWebApiStr<T>(string data, Uri webApiUrl, Token token, int timeout)
{
using (var client = new ExtendedWebClient(webApiUrl, timeout))
{
try
{
client.Headers[HttpRequestHeader.ContentType] = "application/json";
if (token != null)
{
client.Headers[HttpRequestHeader.Authorization] = string.Format("{0} {1}", token.TokenType, token.AccessToken);
}
var response = client.UploadString(webApiUrl, data);
return JsonConvert.DeserializeObject<T>(response);
}
catch (WebException ex)
{
throw new Exception(ex.Message);
}
}
}

您好,您可能需要使用以下类才能将您的json数据转换为类对象
public class EmployeesTraining
{
public int CODCOLIGADA { get; set; }
public string CHAPA { get; set; }
public string NOME { get; set; }
public string CCUSTO { get; set; }
public string Departamento { get; set; }
public string CODPOSTO { get; set; }
public string POSTO { get; set; }
public string TREINAMENTO { get; set; }
public string REALIZADO_EM { get; set; }
public string VALIDADE { get; set; }
}
public class RootObject
{
public List<EmployeesTraining> EmployeesTrainings { get; set; }
public bool HasErrors { get; set; }
public List<string> Errors { get; set; }
}
然后,您可以查看EmployeeTrainings列表以访问个人员工详细信息

您可以使用attributes更改序列化字段的名称:
public class EmpTraining
{
[JsonProperty('CODCOLIGADA')]
public int CodColig { get; set; }
[JsonProperty('CHAPA')]
public string EmpID { get; set; }
[JsonProperty('NOME')]
public string Employee { get; set; }
[JsonProperty('CCUSTO')]
public string CostCenter { get; set; }
[Jsonproperty('Departamento')]
public string Department { get; set; }
[JsonProperty('CODPOSTO']
public string WorkstationID { get; set; }
[JsonProperty('POSTO')]
public string Workstation { get; set; }
[JsonProperty('TREINAMENTO')]
public string Training { get; set; }
[JsonProperty('REALIZADO_EM')]
public string CreateDt { get; set; }
[JsonProperty('VALIDADE')]
public string DueDt { get; set; }
}
但是 您提供的错误消息无法正确解释您的问题。它说:
无法将当前JSON对象(例如{“name”:“value”})反序列化为类型'System.Collections.Generic.List`1 [CoderwallDotNet.Api.Models.Account]'
因此似乎还有另一个问题,无法回答。请提供完整的代码示例,否则只是在猜测。
