相关疑难解决方法(0)

在[之前的帖子]中,我被设置为必须克隆我的实体的路径.我尝试使用[codeproject]中的序列化方法.

因为这些类是由Entity Framework生成的,所以我在自定义.cs中单独标记它们,如下所示:

[Serializable]
public partial class Claims
{
}

但是,当检查时(在克隆方法中):

if (Object.ReferenceEquals(source, null))
{

被击中,我得到错误:

System.ArgumentException was unhandled by user code
  Message=The type must be serializable.
Parameter name: source
  Source=Web
  ParamName=source
