无法在C＃中将dll文件添加到visual studio

Question

I'm new to coding in C#, and I'm using Microsoft Visual Studio 2012. My problem is that when I'm adding a reference from a dll file, it's highlighting in red the import "using alglibnet2;" I am trying to add a reference to my code from Alglib to calculate the covariance matrix covm(). I did put the dll file in a lib folder with my code too. Any help would be appreciated. thanks!
