Question

我需要在CRM 2013中编写插件来做两件事：

如果statecode = 3且字段el_meeting_in_outlook_id为空I 需要创建一个新的appoitment。
如果statecode = 3且字段el_meeting_in_outlook_id不为空我需要更新现有的appoitment。

这就是我写的：

using Microsoft.Xrm.Sdk;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using tmura_Entity_Plugins;

namespace tmura_Entity__Plugins
{
    public class postCreateUpdateServiceAppointment : Plugin
    {
        public postCreateUpdateServiceAppointment()
            : base(typeof(postCreateUpdateServiceAppointment))
        {
            base.RegisteredEvents.Add(new Tuple<int, string, string, Action<LocalPluginContext>>(40, "Create", null, new Action<LocalPluginContext>(ExecutePostCreate)));
            base.RegisteredEvents.Add(new Tuple<int, string, string, Action<LocalPluginContext>>(40, "Update", null, new Action<LocalPluginContext>(ExecutePostUpdate)));

        }

        private void ExecutePostCreate(LocalPluginContext obj)
        {
            Logger.WriteMessage("Enter ExecutePostCreate", CrmLogService.MessageLevel.Info, "");
            if ((obj.PluginExecutionContext.InputParameters.Contains("Target")) && (obj.PluginExecutionContext.InputParameters["Target"] is Entity))
            {
                Entity serviceAppontment = (Entity)obj.PluginExecutionContext.InputParameters["Target"];
                if (serviceAppontment.LogicalName != "serviceappointment")
                    return;

                Logger.WriteMessage("", CrmLogService.MessageLevel.Info, "");

                if ((serviceAppontment.Attributes.Contains("statecode")) || ((int)(serviceAppontment.Attributes["statecode"]) == 3) && (serviceAppontment.Attributes["el_meeting_in_outlook_id"] == null))
                {
                    try
                    {
                        Entity appointment = new Entity("appointment");
                        appointment.Attributes.Add("subject", "Opened automatically");
                        appointment.Attributes.Add("description", "Just Checking");
                        appointment.Attributes.Add("el_serviceappointment_id", new EntityReference("serviceappointment", serviceAppontment.Id));
                        appointment.Attributes.Add("scheduledstart", DateTime.Now.AddDays(7));
                        appointment.Attributes.Add("scheduledend", DateTime.Now.AddDays(7));

                        obj.OrganizationService.Create(appointment);
                    }                      
                    catch (Exception ex)
                    {
                        Logger.WriteException(ex);
                    }
                }
                else if (((int)(serviceAppontment.Attributes["statecode"]) == 3) && (serviceAppontment.Attributes["el_meeting_in_outlook_id"] != null))
                {
                    //TODO
                }
            }
        }
    }
}

我不知道在第二部分写什么应该更新约会。我试图在网上搜索但没有成功。

你能帮忙吗？

Answer 1

在您定义已注册事件的位置，您必须将＆＃34; serviceappointment＆＃34;，即实体逻辑名称，而不是null。

然后将(serviceAppontment.Attributes.Contains("statecode")) || ((int)(serviceAppontment.Attributes["statecode"]) == 3)替换为(serviceAppontment.Attributes.Contains("statecode")) && ((OptionSetValue)(serviceAppontment.Attributes["statecode"]).Value == 3)，因为字段＆＃34;州代码＆＃34;是一个OptionSet。也替换|| by＆amp;＆amp;，因为当serviceAppontment.Attributes.Contains("statecode"))为false时，((OptionSetValue)(serviceAppontment.Attributes["statecode"]).Value将抛出NullReferenceException。

要更新现有约会，看起来在约会实体中有一个查找到serviceappointment实体。因此，您必须检索与serviceappointment相关的所有约会。您可以使用此查询：

QueryExpression queryExp = new QueryExpression
{
    EntityName = "appointment",
    ColumnSet = new ColumnSet("subject", "description", "scheduledstart", "scheduledend"),
    Criteria = new FilterExpression
    {
       Conditions = { new ConditionExpression("el_serviceappointment_id", ConditionOperator.Equal, serviceAppontment.Id) }
    }

};

EntityCollection collection = obj.OrganizationService.RetrieveMultiple(queryExp);

if (collection.Entities.Count > 0)
{
    // now that you have all the appointments related with the serviceappoitement 
    // you can update de any appointment you want
    obj.OrganizationService.Update(appointment);
}

Answer 2

使用serviceappoitnment中查找字段中的值更新记录，以便检索serviceappoitment记录Entity svcApp = obj.OrganizationService.Retrieve(serviceAppontment.LogicalName, serviceAppontment.Id, new ColumnSet("<lookup_field_in_serviceappoitnment>");

您需要在查询表达式中向collumnset添加属性requiredattendees，然后更新该appoitment

if(appointment.Attributes.Contains("requiredattendees") == true)
{
    appointment.Attributes["requiredattendees"] = svcApp.Attributes["<lookup_field_in_serviceappoitnment>"];
}
else
{
    appointment.Attributes.Add("requiredattendees", svcApp.Attributes["<lookup_field_in_serviceappoitnment>");
}
