如何将此 Json（Header + 来自 SAP 的项目）反序列化为模型

Question

我们正在使用 Netweaver Gateway 从 SAP 获取数据。我有一个 class，我将其与 JsonConvert.DeserializeObject 一起使用，以将 JSON 转换为我的模型。效果很好。

但现在我们正在使用 HEADERS 和 ITEMS。

无法将其转换为（嵌套）模型。

我从 Netweaver Gateway 得到了这个 JSON return：

{


"d": {
        "__metadata": {
            "id": "http://xxx:8000/sap/opu/odata/sap/ZLOTO_POC_SRV/WorkPermit_hdrSet('1')",
            "uri": "http://xxx:8000/sap/opu/odata/sap/ZLOTO_POC_SRV/WorkPermit_hdrSet('1')",
            "type": "ZLOTO_POC_SRV.WorkPermit_hdr"
        },

        }
    }

我相信您可能需要查看您的模型，因为它们可能需要更新以处理结构。

因为我尝试了几次，但模型中似乎存在冗余；正如我命名的那样，Result。一旦我使 class 具有所有 可能的 属性，它就变成了两个级别的 go-to class；然后反序列化。

这是我的反序列化行：

var sap = JsonSerializer.Deserialize<SAPData>(GetData());

型号

public class SAPData
{
    public Result d { get; set; }   
}

public class Result
{
    public __metadata __metadata { get; set; }
    public string WpNr { get; set; }
    public string WoNr { get; set; }
    public string Desc1 { get; set; }
    public string Desc2 { get; set; }
    public string Loc1 { get; set; }
    public string Loc2 { get; set; }
    public string Execution { get; set; }
    public string ExecDept { get; set; }
    public string ExecComp { get; set; }
    public string SupExec { get; set; }
    public string SupExecTel { get; set; }
    public string VpkInstr { get; set; }
    public string VpkInstrTel { get; set; }
    public string WorkSup { get; set; }
    public string WorkSupTel { get; set; }
    public string Status { get; set; }
    public string ValidFrom { get; set; }
    public string ValidTo { get; set; }
    public string CreateUser { get; set; }
    public string ChangeUser { get; set; }    
    public string WoOper { get; set; }
    public string Desc { get; set; }

    public WorkPermit_hdr_itm_nav WorkPermit_hdr_itm_nav { get; set; }

}

public class __metadata
{
    public string id { get; set; }
    public string uri { get; set; }
    public string type { get; set; }
}

public class WorkPermit_hdr_itm_nav
{
    public List<Result> results { get; set; }
}
