c# - 系统.Delegate System.Reflection.MethodInfo.CreateDelegate(System.Type)

Question

据我所知，这个错误在过去发生过，当时 Ninject 和站点包的目标是 4.x，并且彼此不匹配。我检查了我的机器，它们匹配 - 都是 4.0。

我只是花了一些时间更新我项目中的所有 Nu-Get 包。在此之前，并没有出现这个错误。

如何消除这个错误？

这是我的完整错误输出:

Answer 1

.net 4.5 中不存在该方法 - 在此之前，应改用 Delegate.CreateDelegate。在我看来，NInject 可能在 4.0 nuget 包中错误地使用了该方法，在这种情况下，您应该将其报告为 NInject 中的错误。

首先要做的是检查您使用的 dll 版本是否正确，即特别是 4.0 版本。

之后，其中之一:

• 回滚到较早的 NInject 版本
• 升级您的 .net 框架版本
• 下载代码，修复它并提交补丁
