我已经将视图状态存储在会话中。但是，当我使用更新面板时，我仍然看到：

有什么办法可以防止它被发送作为回应？

从stackoverflow中提取：

__VIEWSTATE 字段也用于存储控制状态，它不是可选的。此外，如果我没记错的话，视图状态中包含的信息用于验证回发（并且启用了验证，这是默认设置）。因此，只要您拥有带有 runat="server" 的表单，您就会拥有一个 viewstate 字段。但是，如果禁用所有视图状态，您应该会注意到字段大小要小得多。

顺便说一句，有一些技巧可以删除视图状态。检查以下帖子：

使用 Regex 覆盖 Render 并剥离 ViewState。

在 UpdatePanel 上设置“EnableViewState=false”。这将禁用其中包含的所有子控件的 ViewState。或者，如果您需要更精细的方法，您也可以逐个控件禁用 ViewState。
