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

我已尝试执行建议的修复

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

我试着把它放在一些疯狂的数字

<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那么多）。 我正在使用 asp.net mvc 3（剃刀）。 我正在使用 .net 4.0。

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

Answer 1

使用更合理的值，例如32000 ，对我来说效果很好。

有没有一种方法可以将它限制在允许的 forms 上，而不是像现在这样全局？

不，我认为不可能按表单处理此设置。 这是因为在路由发生之前很早就解析了这些值，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，所以它的最大值可以是 integer (int.MaxValue: 2,147,483,647)
2. 最小值为 1
3. 默认值为 1000
