Importing an external mesh in Unity during runtime with code?

Hi, i’m currently trying to develop a standalone application that should import an external .obj file and show it in front of a camera.
I am not sure but i think that it should work as this:
1)Reading vertexs, UVs and triangles from the obj i need to import
2)assign them to a mesh variable
3)change a GameObject’s mesh to the mesh variable i created.
But i don’t know how to read vertexs, UVs and triangles from the external file!
May somebody give me some hints?

Copy-Paste, make an ObjImporter variable and set your Mesh = ObjImporter.ImportFile(“FilePath”);

Even if that’s not the type of answer i asked for, thanks anyway, that could save me a lot of work O.O
