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

我已嘗試執行建議的修復

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

我試着把它放在一些瘋狂的數字

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

但它仍然給我同樣的錯誤（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。

我正在通過 jquery ajax(seralizeArrary) 發送整個表格，所以我不知道這是否與它有關。

Answer 1

使用更合理的值，例如32000 ，對我來說效果很好。

有沒有一種方法可以將它限制在允許的 forms 上，而不是像現在這樣全局？

不，我認為不可能按表單處理此設置。 這是因為在路由發生之前很早就解析了這些值，但只有在路由之后才知道它屬於什么“形式”。

Answer 2

以下是限制：

1. MaxHttpCollectionKeys 是一個 int，所以它的最大值可以是 integer (int.MaxValue: 2,147,483,647)
2. 最小值為 1
3. 默認值為 1000
