#39;Operation is not valid due to the current state of the object#39; error during postback(回发期间的“由于对象的当前状态,操作无效错误)
问题描述
我有一个运行良好的 aspx 页面,但突然我收到错误消息由于对象的当前状态,操作无效."每当回发完成时.
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.FillFromEncodedBytes(字节 [] 字节,编码编码)
在 System.Web.HttpRequest.FillInFormCollection()
at System.Web.HttpValueCollection.ThrowIfMaxHttpCollectionKeysExceeded()
at System.Web.HttpValueCollection.FillFromEncodedBytes(Byte[] bytes, Encoding encoding)
at System.Web.HttpRequest.FillInFormCollection()
有人可以帮忙吗?
推荐答案
有人在您的页面上发布了很多表单字段.最近的安全更新引入的新默认最大值为 1000.
Somebody posted quite a few form fields to your page. The new default max introduced by the recent security update is 1000.
尝试在 web.config 的 <appsettings>
块中添加以下设置.在此块中,您将最大化 MaxHttpCollection 值,这将覆盖 .net Framework 设置的默认值.您可以根据您的表单需要相应地更改值
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
