构造函数或显式转换

在使用linq to sql时,我创建了一个单独的类来将数据传送到web页面。为了简化这些ferry对象的创建,我要么使用专门的构造函数,要么使用显式转换运算符。我有两个问题。

首先,从可读性的角度来看,哪种方法更好?

其次,虽然生成的clr代码对我来说似乎是相同的,但是在某些情况下,编译器会对其中一个代码进行不同的处理(在lambda或类似代码中)。

示例代码(databasefoo使用专用构造函数,businessfoo使用显式运算符):

public class DatabaseFoo
{
    private static int idCounter; // just to help with generating data
    public int Id { get; set; }
    public string Name { get; set; }

    public DatabaseFoo()
    {
        Id = idCounter++;
        Name = string.Format("Test{0}", Id);
    }
    public DatabaseFoo(BusinessFoo foo)
    {
        this.Id = foo.Id;
        this.Name = foo.Name;
    }
}

public class BusinessFoo
{
    public int Id { get; set; }
    public string Name { get; set; }

    public static explicit operator BusinessFoo(DatabaseFoo foo)
    {
        return FromDatabaseFoo(foo);
    }


    public static BusinessFoo FromDatabaseFoo(DatabaseFoo foo)
    {
        return new BusinessFoo {Id = foo.Id, Name = foo.Name};
    }
}

public class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Creating the initial list of DatabaseFoo");
        IEnumerable<DatabaseFoo> dafoos = new List<DatabaseFoo>() { new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo()};

        foreach(DatabaseFoo dafoo in dafoos)
            Console.WriteLine(string.Format("{0}\t{1}", dafoo.Id, dafoo.Name));

        Console.WriteLine("Casting the list of DatabaseFoo to a list of BusinessFoo");
        IEnumerable<BusinessFoo> bufoos = from x in dafoos
                                          select (BusinessFoo) x;

        foreach (BusinessFoo bufoo in bufoos)
            Console.WriteLine(string.Format("{0}\t{1}", bufoo.Id, bufoo.Name));

        Console.WriteLine("Creating a new list of DatabaseFoo by calling the constructor taking BusinessFoo");
        IEnumerable<DatabaseFoo> fufoos = from x in bufoos
                                         select new DatabaseFoo(x);

        foreach(DatabaseFoo fufoo in fufoos)
            Console.WriteLine(string.Format("{0}\t{1}", fufoo.Id, fufoo.Name));
    }
}
