Write a common plugin for Create/Update/Delete events in Dynamics CRM

 If you want to write a common plugin for Create/Update/Delete events in Dynamics CRM 2011 then only you need to take care of “context.InputParameters[“Target”]”. In case of Create/Update event “context.InputParameters[“Target”] is Entity” and in case of Delete event “context.InputParameters[“Target”] is EntityReference”. Below is the sample code for the same:

public void Execute(IServiceProvider serviceProvider) {      // Obtain the execution context from the service provider.      IPluginExecutionContext context = (IPluginExecutionContext)      serviceProvider.GetService(typeof(IPluginExecutionContext));      // Obtain the organization service reference.      IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));      IOrganizationService service = 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)      {           if (context.MessageName == "Create")           {                //Code to be executed during Create event of an entity           }           else if (context.MessageName == "Update")           {                //Code to be executed during Update event of an entity           }       }       else if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is EntityReference)       {           if (context.MessageName == "Delete")           {               //Code to be executed during Delete event of an entity           }       } }
