【问题描述】:
C# 和 JSON 的新手,但基本上我必须在 SSIS 中使用 C# 脚本组件从 Web 服务中提取数据。我最初可以使用不同的 JSON 格式来完成它,但是这个包含一个数组。 我收到以下错误:
“数组的反序列化不支持类型 'Rootobject'。”
下面是我如何调用反序列化器:
//Deserialize our JSON
JavaScriptSerializer sr = new
jsonResponse = sr.Deserialize<Rootobject>(responseFromServer);
这是我的 JSON 结构(不是全部,因为相当大):
[
{
"status":"SUCCESS",
"object":{
"responseStatusCode":0,
"productId":"35100003",
"cansimId":"251-0008",
"cubeTitleEn":"Average counts of young persons in provincial and territorial correctional services",
"cubeTitleFr":"Comptes moyens des adolescents dans les services correctionnels provinciaux et territoriaux",
"cubeStartDate":"1997-01-01",
"cubeEndDate":"2017-01-01",
"frequencyCode":12,
"nbSeriesCube":174,
"nbDatapointsCube":3468,
"releaseTime":"2019-05-09T08:30",
"archiveStatusCode":"2",
"archiveStatusEn":"CURRENT - a cube available to the public and that is current",
"archiveStatusFr":"ACTIF - un cube qui est disponible au public et qui est toujours mise a jour",
"subjectCode":[
"350102",
"4211"
],
"surveyCode":[
"3313"
],
"dimension":[ ],
"footnote":[ ],
"correction":[
]
}
}
]
最后是我在 Visual Studio 中通过选择性粘贴获得的 Class 结构:
public class Rootobject
{
public Class1[] Property1 { get; set; }
}
public class Class1
{
public string status { get; set; }
public Object _object { get; set; }
}
public class Object
{
public int responseStatusCode { get; set; }
public string productId { get; set; }
public string cansimId { get; set; }
public string cubeTitleEn { get; set; }
public string cubeTitleFr { get; set; }
public string cubeStartDate { get; set; }
public string cubeEndDate { get; set; }
public int frequencyCode { get; set; }
public int nbSeriesCube { get; set; }
public int nbDatapointsCube { get; set; }
public string releaseTime { get; set; }
public string archiveStatusCode { get; set; }
public string archiveStatusEn { get; set; }
public string archiveStatusFr { get; set; }
public string[] subjectCode { get; set; }
public string[] surveyCode { get; set; }
public Dimension[] dimension { get; set; }
public Footnote[] footnote { get; set; }
public object[] correction { get; set; }
}
public class Dimension
{
public int dimensionPositionId { get; set; }
public string dimensionNameEn { get; set; }
public string dimensionNameFr { get; set; }
public bool hasUom { get; set; }
public Member[] member { get; set; }
}
public class Member
{
public int memberId { get; set; }
public int? parentMemberId { get; set; }
public string memberNameEn { get; set; }
public string memberNameFr { get; set; }
public string classificationCode { get; set; }
public string classificationTypeCode { get; set; }
public int? geoLevel { get; set; }
public int? vintage { get; set; }
public int terminated { get; set; }
public int? memberUomCode { get; set; }
}
public class Footnote
{
public int footnoteId { get; set; }
public string footnotesEn { get; set; }
public string footnotesFr { get; set; }
public Link link { get; set; }
}
public class Link
{
public int footnoteId { get; set; }
public int dimensionPositionId { get; set; }
public int memberId { get; set; }
}
我知道问题在于我如何调用 Deserialize<Rootobject> 和不同的数据类型,但我无法找到解决方案。任何建议表示赞赏。

【问题讨论】:
-
你没有
Rootobject你有一个Class1的数组。这个jsonResponse = sr.Deserialize<Rootobject>(responseFromServer);应该是jsonResponse = sr.Deserialize<Class1[]>(responseFromServer);
