c# - Generic OrderBy -

i'm new on development , want make small change adding orderby existing code. can enlighten me on how orderby piece of code?

    public list<employee> getallemployees()     {         ebll employeebll = new employeebll();         return ebll.getallemployees();     } 

i agree answer t.s. gave, modify return iqueryable instead of returning .tolist() if want leave option further filter list in calling method. example getallemployees().where(e=>e.name="brad") otherwise enumerating list , not taking advantage of using underlying data source heavy lifting of filtering therefore returning more data needed.
