Prevent accounts with specific record types from being deleted

Hello! How can I write a trigger to make it so accounts that have specific record types cannot be deleted? 
Thank you!

You would have to add extra statements to retrieve the additional record types, as well as an or (||) in the if statement.
See example below which checks for 3 record types.  
trigger preventAccountDeletion on Account (before delete) {

	Id recTypeId1 = Schema.SObjectType.Account.getRecordTypeInfosByName().get('RecordTypeNameA').getRecordTypeId();
	Id recTypeId2 = Schema.SObjectType.Account.getRecordTypeInfosByName().get('RecordTypeNameB').getRecordTypeId();
	Id recTypeId3 = Schema.SObjectType.Account.getRecordTypeInfosByName().get('RecordTypeNameC').getRecordTypeId();
	
    for(Account acct : trigger.old){
		if (acct.recordTypeId == recTypeId1 || acct.recordTypeId == recTypeId2 || acct.recordTypeId == recTypeId3){
			acct.addError('This Account Cannot be deleted');
		}
    }
}

    }

}
RecordTypeName is the name of the record type that should not be deleted.

Hi Nadia, did it work?

Hi Steven,

It works, thank you so much! If I wanted to add a second record type, can I just separate the two by a comma?
