C#深拷贝方法 C#中4种深拷贝方法介绍
人气:0想了解C#中4种深拷贝方法介绍的相关内容吗,在本文为您仔细讲解C#深拷贝方法的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#,深拷贝方法,下面大家一起来学习吧。
1:利用反射实现
public static T DeepCopy<T>(T obj) { //如果是字符串或值类型则直接返回 if (obj is string || obj.GetType().IsValueType) return obj; object retval = Activator.CreateInstance(obj.GetType()); FieldInfo[] fields = obj.GetType().GetFields(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static); foreach (FieldInfo field in fields) { try { field.SetValue(retval, DeepCopy(field.GetValue(obj))); } catch { } } return (T)retval; }
2:利用xml序列化和反序列化实现
public T DeepCopy<T>(T obj) { object retval; using (MemoryStream ms = new MemoryStream()) { XmlSerializer xml = new XmlSerializer(typeof(T)); xml.Serialize(ms, obj); ms.Seek(0, SeekOrigin.Begin); retval = xml.Deserialize(ms); ms.Close(); } return (T)retval; }
3:利用二进制序列化和反序列化实现
public static T DeepCopy<T>(T obj) { object retval; using (MemoryStream ms = new MemoryStream()) { BinaryFormatter bf = new BinaryFormatter(); //序列化成流 bf.Serialize(ms, obj); ms.Seek(0, SeekOrigin.Begin); //反序列化成对象 retval = bf.Deserialize(ms); ms.Close(); } return (T)retval; }
4:利用silverlight DataContractSerializer实现,用于在silverlight 客户端使用
public static T DeepCopy<T>(T obj) { object retval; using (MemoryStream ms = new MemoryStream()) { DataContractSerializer ser = new DataContractSerializer(typeof(T)); ser.WriteObject(ms, obj); ms.Seek(0, SeekOrigin.Begin); retval = ser.ReadObject(ms); ms.Close(); } return (T)retval;
补充:第一个已经通过递归实现了深拷贝。
