System.Delegate System.Reflection.MethodInfo.CreateDelegate（System.Type）

据我所知，这个错误发生在过去，当Ninject是，并且站点包的目标是4.x并且彼此不匹配。 我已经检查了我的机器并且它们匹配 – 两者都是4.0。

我花了一些时间来更新项目中的所有Nu-Get包。 在此之前，没有发生此错误。

如何消除此错误？

这是我的完整错误输出：

Answer 1

该方法在.net 4.5中不存在 – 在此之前，应该使用Delegate.CreateDelegate。 听起来像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。

首先要做的是检查你是否正在使用正确的dll版本，即特别是4.0版本。

之后，其中一个：

• 回滚到早期的NInject版本
• 升级您的.net框架版本
• 下载代码，修复代码并提交补丁
