为所有类型扩展一个深拷贝方法

代码 
 1 /// <summary>
 2         /// 深拷贝对象副本
 3         /// </summary>
 4         /// <typeparam name="T"></typeparam>
 5         /// <param name="obj"></param>
 6         /// <returns></returns>
 7          public static T DeepClone<T>(this T obj) {
 8             System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
 9             System.IO.MemoryStream ms = new System.IO.MemoryStream();
10             T copy=default(T);
11             try {
12                 formatter.Serialize(ms, obj);
13                 ms.Seek(0, System.IO.SeekOrigin.Begin);
14                 copy = (T)formatter.Deserialize(ms);
15             } catch (Exception ex) {
16                 throw new Exception("深拷贝对象实例出错。", ex);
17             } finally {
18                 ms.Close();
19             }
20             return copy;
21         }
