C#对象深拷贝

public static T DeepCopy<T>(this 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;}
