错误加载ASP.Net简介 [英] Error Loading ASP.Net Profile

问题描述

我有一个现成的MVC 4应用程序使用AspNetSqlProfileProvider，配置是这样的：

I have an existing MVC 4 application that uses the AspNetSqlProfileProvider, configured like this:

<properties>
    <add name="MyTypeAs" 
         type="System.Collections.Generic.List`1[[My.Namespace.MyTypeA, My.Namespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]" serializeAs="Binary" />
</properties>

现在我想升级系统（不删除旧的配置文件）是这样的：

Now I wish to update the system (without removing the old profiles) like this:

<properties>
    <add name="MyTypeAs" 
         type="System.Collections.Generic.List`1[[My.Namespace.MyTypeA, My.Namespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]" serializeAs="Binary" />
    <add name="MyHashOfInts" 
         type="System.Collections.Generic.HashSet`1[System.Int32]" serializeAs="Binary" />
</properties>

我有没有问题，在增加previous项目的附加属性。如果序列化的数据是从$ P $，其中没有定义的附加属性pvious版本，加载该属性
产生默认值（T）。然而，随着这种变化，当我的控制器执行这一行：

I have had no problem adding additional properties in previous projects. If the serialized data was from a previous version where the additional property was not defined, loading that property yielded default(T). However, with this change, when my controller executes this line:

List<MyTypeA> myTypeAs = 
     (List<MyTypeA>)HttpContext.Current.Profile.GetPropertyValue("MyTypeA");

抛出异常：

试图加载此属性的类型导致以下错误：未能加载类型'System.Collections.Generic.HashSet`1 [System.Int32]

Attempting to load this property's type resulted in the following error: Could not load type 'System.Collections.Generic.HashSet`1[System.Int32]'.

请注意，我引用类型的属性列表与LT; MyTypeA＆GT; 但异常说，它无法加载类型

Notice that I'm referencing a property of type List<MyTypeA> but the Exception says it cannot load the type

System.Collections.Generic.HashSet`1 [System.Int32]

System.Collections.Generic.HashSet`1[System.Int32].

我做出的我是如何规定的web.config中的类型错了吗？是否有其他原因？

Did I make a mistake in how I specified the type in web.config? Is there another cause?

所有这一切都在Visual Studio 2010 SP1与发生选定.NET 4运行。

All of this is happening in Visual Studio 2010 SP1 with the .NET 4 runtime selected.

推荐答案

原来，从不同列表＆LT; T＆GT; ，的HashSet＆LT; T＆GT; 需要一个完全合格的程序集名称

It turns out that, different from List<T>, HashSet<T> requires a fully qualified assembly name.

System.Collections.Generic.HashSet`1 [System.Int32]，System.Core程序，版本= 4.0.0.0，文化=中性公钥= b77a5c561934e089

System.Collections.Generic.HashSet`1[[System.Int32]], System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
