本文介绍了一个用于执行对象深拷贝的实用工具类，该工具类通过序列化和反序列化的方式实现，确保了拷贝的完整性和独立性。特别适用于需要复制复杂对象或避免原始对象被修改的情况。

     public static class ObjectCopier
    {
        /// <summary>
        /// /// Perform a deep Copy of the object.
        /// /// </summary>
        /// /// <typeparam name="T">The type of object being copied.</typeparam>
        /// /// <param name="source">The object instance to copy.</param>
        /// /// <returns>The copied object.</returns>
        public static T Clone<T>(T source)
        {
            if (!typeof(T).IsSerializable)
            { throw new Exception("The type must be serializable."); }
            // Don't serialize a null object, simply return the default for that object
            if (Object.ReferenceEquals(source, null)) { return default(T); }
            IFormatter formatter = new BinaryFormatter(); Stream stream = new MemoryStream();
            using (stream)
            {
                formatter.Serialize(stream, source);
                stream.Seek(0, SeekOrigin.Begin); return (T)formatter.Deserialize(stream);
            }
        }
    }
