推荐答案

您要定位的.Net版本是什么? C#2010中引入了dynamic.

更新:您不能立即使用动态.另外，您根本不需要在发布的代码中使用动态代码.

What is the .Net version you are targeting? dynamic was introduced with C# 2010.

Update: You cannot use dynamic right away then. Also, you simply do not need to use dynamic in the code you have posted.

动态"在C#4.0中定义为上下文关键字.如果您使用的是C#3.0，那么除非您将其定义为动态的，否则您将无法使用动态的.查看更多信息此处 [ ^ ].

"dynamic" is defined as contextual keyword in C# 4.0. If you are using C# 3.0, then you can''t use dynamic unless you define it to be something. See more info here[^].
