我是c＃和VSTO的新手。
我有一个Excel添加，我工作时创建了一个功能区和一些新的按钮，可以执行各种操作。
我在Ribbon.Designer.cs文件中的base.Dispose上得到NullReferenceException，该文件是在插件加载到Excel时发生的。
根据文档的说法，我可能在不使用新关键字的情况下实例化了一些内容，但我不知道在哪里可以找到我没做过的事情！
我今天早些时候确实有这个工作，但没有采取任何备份或连接到源代码管理，事后看来这是一个坏主意！
在例外的时候有很多空的，我不知道这是否有意义？
基本上;我不知道我做了什么突然发生这种情况，我不知道如何调试它，在哪里设置我的休息时间或这块样板如何适合事物的方案。
当我没有包含绝大多数代码时，我并没有指望有人神奇地把这个漏掉，但是对于该做什么的某些方向或解释会很棒！

FWIW，在选中“项目设置”>“为程序集签名”并尝试使用TemporaryKey签名后，我开始收到此异常。
我确定此错误可能是由其他许多错误引起的，但希望对您有所帮助。
