how can done linq?

you can use zip method.

public class myclass {     public int id { get; set; }     public string number { get; set; } } 

then try this:

list<myclass> fist = new list<myclass>();     //add data list<myclass> second = new list<myclass>();   //add data  fist.zip(second,           (i1, i2) => new myclass() { id = i1.id, number = i1.number + i2.number });
