Here is the code to get description field. As David suggested, register the plugin on Win or/and Lose messages of opportunity entity.
public class OpportunityLostWon : IPlugin
{
public void Execute(IServiceProvider ServiceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)ServiceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationService service = HelperClass.GetCRMService(ServiceProvider);
Entity OppClose = (Entity)context.InputParameters["OpportunityClose"];
try
{
if (!OppClose.Contains("description"))
{
throw new InvalidPluginExecutionException("No Description Found");
}
else if (OppClose.Contains("description"))
{
string description = OppClose.GetAttributeValue<string>("description"); // Here you get your description
if ((description == string.Empty) || (description == null))
{
throw new InvalidPluginExecutionException("Description is Empty");
}
}
}
catch (FaultException<OrganizationServiceFault> ex)
{
throw new InvalidPluginExecutionException("An error occurred in Opportunity plug-in", ex);
}
}
}
Hope this helps.
