Use editor class in standalone build possible?

I want to have a file browser. EditorUtility.OpenFilePanel looks great!

But when I puslish a standalone build, I will have compile error:

Assets/Scripts/Uploader/File
Selector/test.js(1,8): BCE0021:
Namespace ‘UnityEngine.EditorUtility’
not found, maybe you forgot to add an
assembly reference?

Is it possbile to use it in standalone build instead of editor?

No, the UnityEditor namespace is only available inside the editor. You have to use something like System.Windows.Forms.OpenFileDialog
