Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.272 

我已经试着做了建议的修复

<appSettings>
   <add key="aspnet:MaxHttpCollectionKeys" value="1001" />
</appSettings>

我试着把它放在一个疯狂的数字上

<add key="aspnet:MaxHttpCollectionKeys" value="10000000000" />

然而，它仍然给我同样的错误(我有很多字段，但没有那么多)。我使用的是asp.net MVC3(剃刀)。我使用的是.net 4.0。

我通过jquery ajax(seralizeArrary)发送了整个表单，所以我不知道这是否与它有关。

Answer 1

使用一个更合理的值，比如32000，这对我来说很好。

有没有办法把它限制在允许它的形式上，而不是像现在看起来那样是全局的？

不，我不认为这是可能的处理每个表单的这个设置。这是因为这些值在路由发生之前就会被解析，但只有在路由之后才会知道这属于什么“形式”。

Answer 2

限制如下：

1. MaxHttpCollectionKeys是一个整数，因此它的最大值可以是一个整数( 2,147,483,647)
2. Minimum int.MaxValue is 1
3. 默认值是1000
