Retrieve data from Custom settings

Question

Is there a way to retrieve data from custom settings using getAll() on the name of the custom setting that is passed dynamically? Eg : If I pass CS1__c as custom setting name -> it should give data of CS1 If I pass CS2__c as custom setting name -> it should give data of CS2 so on

Thanks in advance.

I don't think there is a Salesforce magic method that will do that for your. Your best option I think is to build your own method using Database.query. At the end of the day a custom setting is an object which you can query. So you will have something like :

String objectName = 'CS1__c';
List<SObject> records = Database.query('SELECT ID FROM '+objectName); 

The only thing you will need to do is to get dynamically all the fields of the selected custom setting using Schema.getGlobalDescribe.
