How to map List of classes
// Method to show call usage.
public List<MappedUser> MapListOfUsers(List<User> users)
{
// option 1
List<MappedUser> mappedUsers = users.Select(user => MapSingleUser(user))
.ToList();
// option 2
List<MappedUser> mappedUsers2 =
(from user in users select MapSingleUser(user)).ToList();
}
method to encapsulate mapping itself
private MappedUser MapSingleUser(User user)
{
var mapped = new MappedUser
{
Id = user.Id,
Name = user.Name,
Email = user.Email
};
return mapped;
}
This provides easier and more legible than doing a foreach to iterate everything.
