Get fields from custom object

Question

I have a string which is a name of sObject. I converted the string to a sObject. Now I want to get the fields from the object. When I try to access the fields from sobject (contact) i am getting error

Field expression not allowed for SObject

I want to get the fields from the sObject how it is possible.

Answer 1

Yes when you use Sobject.FieldAPIName then only you receive error

Field expression not allowed for SObject

Because you cant access the value this way.

Solution

You need to use SObject get() method to get the value... Sobject Methods

like

Sobject.get('FieldAPIName')  

This will give you the value of that Field i.e. FieldAPIName..
