C#對象深拷貝方法

對象的拷貝是編程中常用到的，下面提供一個對象深拷貝的方法，挺不錯的

[csharp] 
public object Copy(this object obj) 
        { 
            Object targetDeepCopyObj; 
            Type targetType = obj.GetType(); 
            //值類型  
            if (targetType.IsValueType == true) 
            { 
                targetDeepCopyObj = obj; 
            } 
            //引用類型   
            else 
            { 
                targetDeepCopyObj = System.Activator.CreateInstance(targetType);   //創建引用對象   
                System.Reflection.MemberInfo[] memberCollection = obj.GetType().GetMembers(); 
 
                foreach (System.Reflection.MemberInfo member in memberCollection) 
                { 
                    if (member.MemberType == System.Reflection.MemberTypes.Field) 
                    { 
                        System.Reflection.FieldInfo field = (System.Reflection.FieldInfo)member; 
                        Object fieldValue = field.GetValue(obj); 
                        if (fieldValue is ICloneable) 
                        { 
                            field.SetValue(targetDeepCopyObj, (fieldValue as ICloneable).Clone()); 
                        } 
                        else 
                        { 
                            field.SetValue(targetDeepCopyObj, Copy(fieldValue)); 
                        } 
 
                    } 
                    else if (member.MemberType == System.Reflection.MemberTypes.Property) 
                    { 
                        System.Reflection.PropertyInfo myProperty = (System.Reflection.PropertyInfo)member;

            }
            //引用類型
            else
            {
                targetDeepCopyObj = System.Activator.CreateInstance(targetType);   //創建引用對象
                System.Reflection.MemberInfo[] memberCollection = obj.GetType().GetMembers();

                foreach (System.Reflection.MemberInfo member in memberCollection)
                {

                        }
                        else
                        {
                            field.SetValue(targetDeepCopyObj, Copy(fieldValue));
                        }

                    }
                    else if (member.MemberType == System.Reflection.MemberTypes.Property)
                    {

                        if (info != null)
                        {
                            object propertyValue = myProperty.GetValue(obj, null);
                            if (propertyValue is ICloneable)
