C#如何深度克隆对象_c# 克隆对象

话不多说上代码:

/// <summary>
/// 利用序列化进行对象拷贝,要求对象是序列化的
/// </summary>
/// <typeparam name="T">对象类型</typeparam>
/// <param name="item">源对象</param>
/// <returns>克隆对象</returns>
public T Clone<T>(T item) where T : class
{
    T result = default(T);
    if (null != item)
    {
        MemoryStream ms = new MemoryStream();
        BinaryFormatter bf = new BinaryFormatter();
        bf.Serialize(ms, item);
        ms.Seek(0, SeekOrigin.Begin);
        result = bf.Deserialize(ms) as T;
        ms.Close();
    }
    return result;
}

[Serializable]
public class Person
{
    public string Name { get; set; }
	public string Age { get; set; }
	public string Birthday { get; set; }
}

//use
//var pClone=Clone(p);

利用json来克隆对象,即object->json->object
