Hi partner,
As you konw, these three Pipleline stages means different order to trigger the plugin.
Which Pipleline stage you choose has nothing to do with the code, for example I created a plug-in to calculate the account age based on birthday and here is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Xrm.Sdk.Discovery;
namespace plugin2._0
{
public class UpdateFax : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
//Extract the tracing service for use in debugging sandboxed plug-ins.
ITracingService tracingService =
(ITracingService)serviceProvider.GetService(typeof(ITracingService));
// Obtain the execution context from the service provider.
IPluginExecutionContext context = (IPluginExecutionContext)
serviceProvider.GetService(typeof(IPluginExecutionContext));
// Get a reference to the Organization service.
IOrganizationServiceFactory factory =
(IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationServiceFactory servicefactory =
(IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService client = servicefactory.CreateOrganizationService(context.UserId);
// The InputParameters collection contains all the data passed in the message request.
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
// Obtain the target entity from the input parameters.
Entity entity = (Entity)context.InputParameters["Target"];
// Verify that the target entity represents an account.
// If not, this plug-in was not registered correctly.
if (context.Depth > 1) return;
if (entity.LogicalName == "account")
{
try
{
string birthday = string.Empty;
if (entity.Attributes.Contains("new_birthday1"))
{
birthday = entity.GetAttributeValue<DateTime>("new_birthday1").ToString();
}
var dateBirthday = Convert.ToDateTime(birthday);
var now = DateTime.Now;
int age = now.Year - dateBirthday.Year;
entity["new_age"] = age;
}
catch (Exception e)
{
tracingService.Trace("accountPlugin: {0}", e.ToString());
throw new InvalidPluginExecutionException(e.Message);
}
}
else
return;
}
}
}
}
We could understand the code in this way, the code is only used to execute the action to calculate the age, and I could rigisiter this plug-in both in Pre-validation, Pre-operation and Post-operation without any issue.
The only thing we need to pay attention to is that different Pipleline stage support different message.
Hope it helps.
Best Regards,
Leo
