title: Apply function to all elements of collection through LINQ
body: <p>I have recently started off with LINQ and its amazing. I was wondering if LINQ would allow me to apply a function - any function - to all the elements of a collection, without using foreach. Something like python lambda functions.</p>
  
  <p>For example if I have a int list, Can I add a constant to every element using LINQ</p>
  
  <p>If i have a DB table, can i set a field for all records using LINQ.</p>
  
  <p>I am using C#</p>
