无法从新创建的记录中获取 GUID

Question

随行：

Guid AlertsId = service.Create(NewAlert);
NewAlert["new_alertguid"] = "Spennende: " + AlertsId.ToString();

我正在尝试获取新创建的 GUID。 但什么也没有发生。我没有得到 GUID，工作流程也没有失败。 它也没有在现场写“Spennende”。但我不知道如何找出我做错了什么。

我能做些什么来解决这个问题。大家有没有发现什么问题？

试图在同一字段中插入其他值。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Activities;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;

namespace WordCountWorkflow
{
    public class WordCount : CodeActivity
    {



        [Input("Hvilket felt skal endres")]
        public InArgument<string> FieldToChange { get; set; }

        [RequiredArgument]
        [Input("Tekst som skal telles")]
        public InArgument<string> InputText { get; set; }

        [Output("Antall tegn")]
        public OutArgument<int> CountOfWords { get; set; }


        protected override void Execute(CodeActivityContext context)
        {
            this.CountOfWords.Set(
                context,
                this.InputText.Get<string>(context).Split(
                    new char[] { ' ', '\r', '\n' },
                    StringSplitOptions.RemoveEmptyEntries).Length);
            //------------------
            ITracingService tracingService = context.GetExtension<ITracingService>();
            IWorkflowContext workflowContext = context.GetExtension<IWorkflowContext>();
            IOrganizationServiceFactory serviceFactory = context.GetExtension<IOrganizationServiceFactory>();
            IOrganizationService service = serviceFactory.CreateOrganizationService(workflowContext.UserId);
            Entity NewAlert = new Entity("new_alerts");
            NewAlert["new_name"] = "Navn på alert";
            NewAlert["new_message"] = "Her er beskjed";
            Guid AlertsId = service.Create(NewAlert);
            NewAlert["new_alertguid"] = "Spennende: " + AlertsId.ToString();
        }
    }
}

我试着改成这个：

    ITracingService tracingService = context.GetExtension<ITracingService>();
    IWorkflowContext workflowContext = context.GetExtension<IWorkflowContext>();
    IOrganizationServiceFactory serviceFactory = context.GetExtension<IOrganizationServiceFactory>();
    IOrganizationService service = serviceFactory.CreateOrganizationService(workflowContext.UserId);
    Entity NewAlert = new Entity("new_alerts");
    Guid AlertsId = service.Create(NewAlert);
    NewAlert["new_name"] = "Navn på alert";
    NewAlert["new_message"] = "Her er beskjed " + AlertsId.ToString();
    NewAlert["new_shortmessage"] = "Spennende: " + AlertsId.ToString();

但随后一切都停止了。并且没有填写任何字段。

您可以使用以下代码为记录创建 guid

Entity NewAlert = new Entity("new_alerts");
NewAlert.Id = Guid.NewGuid();
NewAlert["new_name"] = "Navn på alert";
NewAlert["new_message"] = "Her er beskjed";            
NewAlert["new_alertguid"] = "Spennende: " + NewAlert.Id.ToString();
Guid AlertsId = service.Create(NewAlert);

或者你可以创建新对象然后更新它。

Entity NewAlert = new Entity("new_alerts");
NewAlert["new_name"] = "Navn på alert";
NewAlert["new_message"] = "Her er beskjed";
Guid AlertsId = service.Create(NewAlert);        
Entity CompleteNewAlert = new Entity("new_alerts",AlertsId );
CompleteNewAlert ["new_alertguid"] = "Spennende: " + AlertsId.ToString();
service.Update(CompleteNewAlert );
