c# - LINQ to SQL execute method on select -

im new linq i'm trying figure out how execute method lambda expressions.

   public void getdata()     {       using (myclassesdatacontext context = new myclassesdatacontext())                 {                     var problems = (from p in context.problems select p).take(10);                     problems.select(t => displaydata(t.text));                 }      }       public void displaydata(string text)             {               } 

i'm getting error:

the type arguments method 'system.linq.enumerable.select(system.collections.generic.ienumerable, system.func)' cannot inferred usage. try specifying type arguments explicitly.

at line:

 problems.select(t => displaydata(t.text)); 

what doing wrong?

select operator used create projection - i.e. lambda expression passed argument instructs how create new object out of each object in collection.

what want is, instead, perform action on each item collection. use foreach loop that:

var problems = (from p in context.problems select p).take(10);  foreach (var t in problems) {      displaydata(t.text); }
