c# - 使用 C# 中的 API 在 ivanti HEAT 中创建 Note 对象

Question

我的任务是在 C# 中使用 Ivanti HEAT API 创建一个“Note Business Object”这是我试图创建的：

1. 使用此主体创建 CreateNote 方法：

        public Note CreateNote(ServiceRequest parent, string category, string summary, string notes)
        {
            Logger.Verbose($"Heat.CreateNote({parent}, {category}, {summary}, {notes}");

            String type = "Journal#Note";

            List<ObjectCommandDataFieldValue> dataFields = new List<ObjectCommandDataFieldValue>()
            {
                new ObjectCommandDataFieldValue()
                {
                    Name = "Category",
                    Value = category,
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "Summary",
                    Value = summary,
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "Notes",
                    Value = notes
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "ParentLink_Category",
                    Value = "ServiceReq"
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "ParentLink_RecID",
                    Value = parent.RecID
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "Status",
                    Value = "Logged"
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "CreatedDateTime",
                    Value = DateTime.UtcNow.ToString("MM/dd/yyyy HH:mm:ss")
                },
                new ObjectCommandDataFieldValue()
                {
                    Name = "LastModDateTime",
                    Value = DateTime.UtcNow.ToString("MM/dd/yyyy HH:mm:ss")
                },
            };

            return new Note(CreateObject(type, parent, dataFields), this);
        }

2. 使 CreateObject 方法创建一个业务对象：

        private WebServiceBusinessObject CreateObject(String type, WebServiceBusinessObject Parent, List<ObjectCommandDataFieldValue> variables)
        {
            Logger.Verbose($"Entered Heat.CreateObject({Parent}, {variables})");
            ObjectCommandData data = new ObjectCommandData();

            data.ObjectType = type;

            data.Fields = variables.ToArray();

            FRSHEATIntegrationCreateBOResponse response = Client.CreateObject(SessionKey, TenantId, data);
            Logger.Verbose($"Soap response status: {response.status}");
            Logger.Verbose($"Soap response Exception: {response.exceptionReason}");
            Logger.Verbose($"Soap response recId:{response.recId}");
            Logger.Verbose($"Soap response obj:{response.obj}");

            Logger.Verbose($"Exited Heat.CreateObject() => {response.obj}");
            return response.obj;
        }

3. 通过在程序中使用以下调用来测试它

        Note newNote = Heat.CreateNote(SR, $"TestNote - {DateTime.Now.ToString("dd/MM/yy - HH:mm")}", "Test Note", "This test note has been created through the API");

        Console.WriteLine(newNote.RecID);

但后来我得到了这个例外：

System.NullReferenceException：“对象引用未设置为对象的实例。” obj 为空。

我对 Ivanti HEAT API 真的不是很熟悉，而且几乎没有关于它的明确信息。有一个在库中创建任务的示例，这个示例完全有效。

编辑： 这是堆栈跟踪：

这是失败的方法（在 WebServiceBusiness 中）：

        public WebServiceBusinessObjectExtented(WebServiceBusinessObject obj, Heat Heat)
        {
            this.Alias = obj.Alias; <-- null ref ex
            this.BusinessObjectName = obj.BusinessObjectName;
            this.FieldValues = obj.FieldValues;
            this.RecID = obj.RecID;
            this.TableRef = obj.RecID;
            this.Heat = Heat;

            InitializeCommandDate();
        }
