2,745Hi Experts,
I am trying to send email to all required attendees and optional attendees of an appointment using plugin. It works fine on CREATE message but in update message its throwing error as Duplicate key cannot insert.
here is my code.
using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using System;
namespace Send_Email_Plugin
{
// Importnant Note-------------------------------------------------------------------------------------------------------------------
// When you are sending emails you have to go to User profile in CRM from which the email gets triggered, and click on "APPROVE EMAIL"
// The Email Box should configured properly.
//-----------------------------------------------------------------------------------------------------------------------------------
public class SendEmail_Plugin : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
//Tracing Object
ITracingService tracing = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
//ExecutionContext Object
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
//OrganizationServiceFactory Object
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
//OrganizationService Object
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
string functionName = "Execute";
try
{
EntityCollection requiredAttendees;
EntityCollection optionalAttendees;
EntityReference RegardingEntRef;
Entity appointmentEn;
if (context.MessageName == "Update")
appointmentEn = context != null && context.InputParameters.Contains("Target") ? (Entity)context.PostEntityImages["PostImage"] : null;
else if (context.MessageName == "Create")
appointmentEn = context != null && context.InputParameters.Contains("Target") ? (Entity)context.InputParameters["Target"] : null;
else
return;
tracing.Trace("retrieved entity :" + appointmentEn.LogicalName + "Message:" + context.MessageName);
if (appointmentEn.LogicalName == "appointment")
{
tracing.Trace("validated entity..");
if (appointmentEn.Attributes.Contains("requiredattendees") && appointmentEn.Attributes.Contains("optionalattendees") && appointmentEn.Attributes.Contains("regardingobjectid"))
{
tracing.Trace("Validated attendees");
//read regarding field
RegardingEntRef = appointmentEn.GetAttributeValue<EntityReference>("regardingobjectid");
tracing.Trace("regarding : " + RegardingEntRef.Name);
//read required and optional attendees
requiredAttendees = appointmentEn.Attributes.Contains("requiredattendees") ? appointmentEn.GetAttributeValue<EntityCollection>("requiredattendees") : null;
optionalAttendees = appointmentEn.Attributes.Contains("optionalattendees") ? appointmentEn.GetAttributeValue<EntityCollection>("optionalattendees") : null;
var appointmentSubject = appointmentEn.Attributes.Contains("subject") ? appointmentEn.GetAttributeValue<String>("subject") : null;
var appointmentLocation = appointmentEn.Attributes.Contains("location") ? appointmentEn.GetAttributeValue<String>("location") : null;
