Below i am trying to replace User.Name with the name of my picklist field(Change_Owner__c) and then Cody Dren with whatever the user selected from the picklist(Cody D, Kyle W, Jen J etc).  Can someone please help me with this. 

Thanks.

Trigger UpdateOwnerID on Case (before insert, before update) {
       
    User objUser = [select Id from User where User.Name = 'Cody Drennon' limit 1];  
    for (Case objCase : Trigger.new)
    {
        if (objCase.OwnerId <> objUser.Id)               
        {
            objCase.OwnerId = objUser.Id;
        }
    }

}
