Update a number of custom attributes of DynamicEntity with TargetUpdateDynamic.

This code I was used in plugins for updating the custom attributes using Microsoft.Crm.SDK.

using System;
using System.Collections.Generic;
using System.Collections;

// Microsoft Dynamics CRM namespaces
using Microsoft.Crm.Sdk;
using Microsoft.Crm.Sdk.Query;
using Microsoft.Crm.SdkTypeProxy;

...

// Extract the DynamicEntity from the request.
entity = (DynamicEntity)retrieved.BusinessEntity;

// declare a property array
ArrayList arrProps = new ArrayList();

// create some property
CrmBooleanProperty new_withindustry = new CrmBooleanProperty();
new_withindustry.Name="new_withindustry";
new_withindustry.Value= new CrmBoolean();
new_withindustry.Value.Value=true;
arrProps.Add(new_withindustry);

// create another property
CrmMoneyProperty new_industrydeal = new CrmMoneyProperty();
new_industrydeal.Name = "new_industrydeal";
new_industrydeal.Value = new CrmMoney();
new_industrydeal.Value.Value = 12345.0m;
arrProps.Add(new_industrydeal);

//   Update the properties array on the DynamicEntity.
entity.Properties.AddRange((Property[])arrProps.ToArray(typeof(Property)));

// Create the update target.
TargetUpdateDynamic updateDynamic = new TargetUpdateDynamic();

// Set the properties of the target.
updateDynamic.Entity = entity;

//   Create the update request object.
UpdateRequest update = new UpdateRequest();

//   Set request properties.
update.Target = updateDynamic;

//   Execute the request.
UpdateResponse updated = (UpdateResponse)crmService.Execute(update);
