C# Object Initialization and Constructor

#csharp #dotnet #oop #codenewbie

When we have few fields in a class and want to initialize every field in a constructor it should become a little bit messy and maybe we need a few constructors.

public class User
    {
        public string Name;
        public List<string> Roles;

        public User(string name)
        {
            Name = name;
        }

        public User(string name, List<string> roles)
        {
            Name = name;
            Roles = roles;
        }
    }

We can use object initializer syntax, to initialize our properties and reserve the constructor, for the cases when we really need them, removing the constructor our class looks cleaner.

public class User { 
   public string Name; 
   public List<string> Roles; 
}
var test = new User
{
   Name = "Dany",
   Roles = new List<string>() {"Admin", "Normal"},
   Id = 12
};
