获取原始，复杂，ArrayEnumerable类型

Question

我有一个单独的类为我的每个数据库实体，当我创建我的类的对象引用类的属性时，它返回一个循环引用，其中包含其他实体的属性通过FK相关...删除循环引用我想先通过“上下文代理对象”复制对象的副本，然后获取该对象的基本类型，复杂类型，arrayEnumerable类型，并从对象中去除这些类型然后通过Web服务返回对象....

听起来像一个递归浅层克隆。我已经使用了以下内容，但只有一个级别。

public static class EntityBaseExtensions 
{ 
    /// <summary> 
    /// Description: Creates a non-recursive shallow copy of an entity, only including public instance properties decorated with ColumnAttribute. 
    ///     This will return an object without entity references. 
    /// </summary> 
    /// <typeparam name="T"></typeparam> 
    /// <param name="source"></param> 
    /// <returns>A non-recursive shallow copy of a LINQ entity</returns> 
    public static T ShallowClone<T>(this T source) where T : EntityBaseClass 
    { 
     // create an object to copy values into 
     T destination = Activator.CreateInstance<T>(); 

     // get source and destination property infos for all public instance 
     PropertyInfo[] sourcePropInfos = source.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance); 
     PropertyInfo[] destinationPropInfos = source.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance); 

     foreach (PropertyInfo sourcePropInfo in sourcePropInfos) 
     { 
      if (Attribute.GetCustomAttribute(sourcePropInfo, typeof(ColumnAttribute), false) != null) 
      { 
       PropertyInfo destPropInfo = destinationPropInfos.Where(pi => pi.Name == sourcePropInfo.Name).First(); 

       destPropInfo.SetValue(destination, sourcePropInfo.GetValue(source, null), null); 
      } 
     } 

     return destination; 
    } 

}
