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

我尝试过建议的解决方法

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

我试过把它放在一个疯狂的数字

<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 mvc 3（razor）。我正在使用.net 4.0。

我通过jquery ajax（seralizeArrary）发送整个表单，所以我不知道是否与它有关。

Answer 1

使用更合理的值，例如32000，这对我来说很合适。

  

是否还有一种方法可以将其限制为允许使用哪种形式而不是全局，因为它现在似乎是正确的？

不，我不认为每个表单都可以处理此设置。这是因为在路由发生之前对值进行了非常均衡的解析，但只有在路由之后才知道它属于什么“形式”。

Answer 2

以下是限制：

1. MaxHttpCollectionKeys是一个int，所以它可以有一个整数的最大值（int.MaxValue：2,147,483,647）
2. 最小值为1
3. 默认值为1000
