LINQ select Top 1 from List<T>

Question

My Code is as below

List<User> UserDetails = AllUser.Where(x => x.UserId == 5).ToList(); 

This Code will return all User with userID=5 and store it to my list , If All user have 5 record with UserId=5 , it will store all 5 record to UserDetail , How can I only store the first row of the record instead of all 5, because the other 4 is just redundancy from AllUser

Answer 1

User UserDetails = AllUser.FirstOrDefault(x => x.UserId == 5); 

Answer 2

You can use .First()

User UserDetails = AllUser.First(x => x.UserId == 5);
