我想将c＃列表转换为JArray

Posted 2023-02-19

如果我使用了JARRAY.FROMOBJECT，我得到了一个空的骨骼json，有人可以帮我让我知道如何将列表转换为专业术语。谢谢

class EGTenantCreated

internal string id  get; set; 
internal string subject  get; set; 
internal EGData data  get; set; 
internal string eventType  get; set; 
internal string eventTime  get; set; 
internal string dataVersion  get; set; 
internal string metadataVersion  get; set; 
internal string topic  get; set; 


class EGData

internal string TenantId  get; set; 
internal string TenantName  get; set; 
internal string AdministratorEmail  get; set; 
internal string ProductId  get; set; 
internal string PackageInstanceId  get; set; 
internal string CorrelationId  get; set; 


public List<EGTenantCreated> UpdateEGTenant()

DateTime date = new DateTime();
string tenantName = "Tenant" + date.Day.ToString() + date.Month.ToString() + 
date.Year.ToString() + "_"
+ date.Hour.ToString() + date.Minute.ToString();

string adminEmail = "user" + date.Day.ToString() + date.Month.ToString() + 
date.Year.ToString() + "_"
+ date.Hour.ToString() + date.Minute.ToString() + "@testmail.com";

EGData egData = new EGData();
egData.TenantId = Guid.NewGuid().ToString();
egData.TenantName = tenantName;
egData.AdministratorEmail = adminEmail;
egData.ProductId = "Erp";
egData.PackageInstanceId = "522b0dc0-5db9-437d-97cc-cd4c742b1b22";
egData.CorrelationId = Guid.NewGuid().ToString();

EGTenantCreated egTenant = new EGTenantCreated();
egTenant.id = Guid.NewGuid().ToString();
egTenant.subject = "/DeploymentRegistry/TenantCreated";
egTenant.eventType = "TenantCreated";
egTenant.eventTime = "2019-10-04T20:02:54.9411815Z";
egTenant.dataVersion = "1.0.0";
egTenant.metadataVersion = "1";
egTenant.topic = "topictest";
egTenant.data = egData;

List<EGTenantCreated> list = new List<EGTenantCreated>();
list.Add(egTenant);

return list;

var list = UpdateEGTenant();
var jArray = JArray.FromObject(list);  //here i get an empty json

这里是我得到错误的地方，当我打印jArray.ToString（）时，我得到了一个空的json框架，并且没有将我的列表转换成期望的jarray对象。这是真实的代码。

您看到的问题是因为您的属性是internal。要解决此问题，可以使它们成为public和类internal（如果未指定修饰符，则为默认值），或者可以将JsonProperty属性放在每个属性上：

class EGTenantCreated

    [JsonProperty]
    internal string id  get; set; 
    [JsonProperty]
    internal string subject  get; set; 
    [JsonProperty]
    internal EGData data  get; set; 
    [JsonProperty]
    internal string eventType  get; set; 
    [JsonProperty]
    internal string eventTime  get; set; 
    [JsonProperty]
    internal string dataVersion  get; set; 
    [JsonProperty]
    internal string metadataVersion  get; set; 
    [JsonProperty]
    internal string topic  get; set; 


class EGData

    [JsonProperty]
    internal string TenantId  get; set; 
    [JsonProperty]
    internal string TenantName  get; set; 
    [JsonProperty]
    internal string AdministratorEmail  get; set; 
    [JsonProperty]
    internal string ProductId  get; set; 
    [JsonProperty]
    internal string PackageInstanceId  get; set; 
    [JsonProperty]
    internal string CorrelationId  get; set;
