Sharing and Unsharing Records in CRM 2011

Hi All, Here I am going to share Account record with a user and then unsharing the account from the user in CRM 2011. Here is the logic to share and unshare records

sharing

 // Create the request object and set the target and principal access
GrantAccessRequest grantRequest = new GrantAccessRequest()
            {
                Target = new EntityReference(Account.EntityLogicalName, accountId),
                PrincipalAccess = new PrincipalAccess()
                {
                    Principal = new EntityReference(SystemUser.EntityLogicalName, userId),
                    AccessMask = actionRights
                }
            };

 // Execute the request.
GrantAccessResponse granted = (GrantAccessResponse)service.Execute(grantRequest);


Unsharing


 // Create the request object and set the target and revokee.
            RevokeAccessRequest revokeRequest = new RevokeAccessRequest()
            {
                Target = new EntityReference(Account.EntityLogicalName, accountId),
                Revokee = new EntityReference(SystemUser.EntityLogicalName, accountuserId)
            };

// Execute the request.
 RevokeAccessResponse revoked = (RevokeAccessResponse)service.Execute(revokeRequest);
