无法加载文件或程序集 ' 版本=3.0.1.0、公钥令牌=null 或其依赖项之一。需要强名称程序集。

Question

在我的应用程序中，在给出程序集强密钥名称后，包括VS 2012命令提示符的第三方dll，我得到程序集加载错误。

我已经从所有解决方案中删除了所有bin和obj文件夹，并重新构建和批量构建，包括清理解决方案，还更改了程序集版本，但仍然无法找到确切的错误。

你上面列出的是一团乱麻。然而，我上周刚刚犯了这个错误，所以你很幸运。为了使强名称工作，您需要

1. 创建密钥
2. 将密钥添加到程序集文件
3. 项目属性中添加签名

这是它!关于如何做到这一点的所有信息都在这里http://www.codeproject.com/Articles/7859/Building-COM-Objects-in-C

为了公开COM对象，您的类库程序集还必须有一个强有力的名字。要创建强名称，请使用实用程序SN.EXE .

崩溃|复制代码sn -k Database_COM_Key。蛇打开AssemblyInfo.cs并修改行

崩溃|复制代码[汇编:AssemblyKeyFile("Database_COM_Key.snk")]构建对象。构建还生成一个类型库，该类型库可以导入到您的托管或非托管代码。

你也可以参考我在堆栈上的问题。
