I want to show a simple use of Lamda expression in our C# code which remove tedious lines of code,
is a object of Database which has a list of Contact
I am going to search a contact by a Id
which is used as parameter in a function we can find the contact by three way
1. By using foreach/for loop and inside loop we can check if current contact has same id as parameter
2. using LINQ which is written over here as commented.
3. Using LAMDA Exp. which is also written I am going to use in future
<pre lang="c#">public Contact GetContact(int Id)<br />
//return (from c in _entities.Contacts //LINQ<br />
// where c.Id == Id<br />
// select c).FirstOrDefault();<br />
return _entities.Contacts.FirstOrDefault(m => m.Id == Id); //Lamda<br />
Obviously lambda expression will make life easier. We can use find function and many more using lambda expression...
