C# Lambda expressions: Why should I use them?

Question

I have quickly read over the Microsoft Lambda Expression documentation.

This kind of example has helped me to understand better, though:

delegate in         


        

Answer 1

Anonymous functions and expressions are useful for one-off methods that don't benefit from the extra work required to create a full method.

Consider this example:

 List people = new List { "name1", "name2", "joe", "another name", "etc" };
 string person = people.Find(person => person.Contains("Joe"));

versus

 public string FindPerson(string nameContains, List persons)
 {
     foreach (string person in persons)
         if (person.Contains(nameContains))
             return person;
     return null;
 }

These are functionally equivalent.
