Object.MemberwiseClone

【Object.MemberwiseClone】

　　Creates a shallow copy of the current Object.

　　protected object MemberwiseClone()

　　C#的 Object对象中没有Clone()方法，只有MemberwiseClone()。下面是官方给的ShallowCopy、DeepCopy的示例。　　

public class Person
{
    public int Age;
    public string Name;
    public IdInfo IdInfo;

    public Person ShallowCopy()
    {
       return (Person) this.MemberwiseClone();
    }

    public Person DeepCopy()
    {
       Person other = (Person) this.MemberwiseClone();
       other.IdInfo = new IdInfo(IdInfo.IdNumber);
       other.Name = String.Copy(Name);
       return other;
    }
}
