“操作无效由于对象的当前状态”的错误时回传 [英] 'Operation is not valid due to the current state of the object' error during postback

问题描述

我就有一个运作良好的aspx页面，但突然我得到的错误操作是无效的，由于对象的当前状态。每当回发就完成了。

I had an aspx page which was working well, but suddenly I am getting the error "Operation is not valid due to the current state of the object." whenever a postback is done.

堆栈跟踪是：

在
  System.Web.HttpValueCollection.ThrowIfMaxHttpCollectionKeysExceeded（）

  在System.Web.HttpValueCollection.FillFromEn codedBytes（字节[]字节，
  编码编码）
在System.Web.Htt prequest.FillInFormCollection（）

at System.Web.HttpValueCollection.ThrowIfMaxHttpCollectionKeysExceeded()
at System.Web.HttpValueCollection.FillFromEncodedBytes(Byte[] bytes, Encoding encoding)
at System.Web.HttpRequest.FillInFormCollection()

有人能帮助？

推荐答案

有人贴了不少表单字段到您的网页。新的默认的最大受近期的安全更新介绍的是1000。

somebody posted quite a few form fields to your page. The new default max introduced by the recent security update is 1000.

试着在你的web.config的＆LT添加下面的设置;的AppSettings＆GT; 块。在此块你最大化MaxHttpCollection值，这将覆盖由.NET框架设置的默认值。你可以更改相应的值按您需要的形式

Try adding the following setting in your web.config's <appsettings> block. in this block you are maximizing the MaxHttpCollection values this will override the defaults set by .net Framework. you can change the value accordingly as per your form needs

<appSettings>
    <add key="aspnet:MaxHttpCollectionKeys" value="2001" />
 </appSettings>
