推荐答案

作为请求的视图状态传递回浏览器嵌入生成的网页的HTML代码中的序列化再presentation这是有道理的，只有serialisable对象可以放置在它（否则它可能无法重新present在它的内蕴。）这视图状态，然后在下一个请求期间反序列化。

As the viewstate of a request is passed back to the browser as a serialised representation embedded within the generated page's HTML it makes sense that only serialisable objects can be placed within it (otherwise it may fail to represent that which it contains.) That viewstate is then de-serialised during the next request.

如果您使用的是POCO的将其标记为serialisable应该足够简单。有关于如何理解作品的ViewState一个很好的资源，它是什么等在这里：

If you are using POCO's marking them as serialisable should be trivial enough. There is an excellent resource on understanding how viewstate works, what it is etc. here:
