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

我已经尝试过建议的修复

<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" />

但它仍然给我同样的错误（我有很多字段但不是很多）。我正在使用 asp.net mvc 3（剃须刀）。我正在使用.net 4.0。

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

使用更合理的值，例如32000, 这对我来说很好。

有没有办法将其限制为允许使用的形式而不是像现在看起来那样的全局形式？

不，我认为不可能按表单处理此设置。这是因为值在路由发生之前很早就被解析了，但只有在路由之后才能知道它属于什么“形式”。

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
