XYZ - Random Number



Logic:

• Generate Random Number using Random().Next() message
• Convert Random Number to String
• Get the first three from random number using Substring()method
• Get the attribute created on and convert to DateTime 
• Convert the time to local time and convert to String (with DDMMYYYYHHMMSSMSS format)
• Append and assign the value to the desired attribute

Code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using Microsoft.Crm.Sdk;

using Microsoft.Xrm.Sdk;

namespace Auto_Number_SDK

{

    public class CaseNumber:IPlugin

    {

        public void Execute(IServiceProvider serviceProvider)

        {

            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

            ITracingService tracingService =

                (ITracingService)serviceProvider.GetService(typeof(ITracingService));

            try

            {

                Entity incident = context.InputParameters["Target"] as Entity;

                var number = new Random().Next().ToString();

                var rnum = number.Substring(0, 3);

                var time = ((DateTime)incident.Attributes["createdon"]).ToLocalTime().ToString("ddMMyyyyHHmmssfff");

                incident.Attributes["ticketnumber"] = "A" + time+rnum;

                

            }

            catch (Exception ex)

            {

                tracingService.Trace("CaseNumber: {0}", ex.ToString());

                throw;

            }

        }
