We will learn how to read / get and write / set values in various different fields on Microsoft Dynamics 365 CRM using plugins. A field in Microsoft CRM is the equivalent of a column in a database table, here the only difference is that an entity correlates to a table. We can perform all types of operations using the plugins where there can be scenarios where we have to set or get values from an entity field to suffice the operation logic. In the below examples, we have performed get and set operations of multiple fields in the retrieved Target entity.
Read & Write values in string or text field
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Xrm.Sdk;
namespace CRM_Crate___My_Sample_Plugin
{
public class Plugin : IPlugin
{
//Main Execute Method.
public void Execute(IServiceProvider serviceProvider)
{
//Initializing Service Context.
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(context.UserId);
try
{
//Defining Entity Object.
Entity eTarget = null;
if (context.MessageName == "Create")
{
//Retrieving Target Entity.
eTarget = (context.InputParameters.Contains("Target") && context.InputParameters["Target"] != null) ?
context.InputParameters["Target"] as Entity : null;
//Triggering The Logic If Target Is Not Null.
if (eTarget != null)
{
//Reading Value From String Field.
string readField = eTarget.GetAttributeValue<string>("fieldschemaname");
//Setting Value In String Field.
eTarget.Attributes.Add("fieldschemaname", "Any Text Value");
//Sending Update Request.
service.Update(eTarget);
}
}
