Call native file manager from Unity Application C#

Good day all. I am writing a project in Unity on C#. I need that user can choose a file from computer and this file will upload to server. How to call a native file browser? (for example, Windows Explorer) and then upload selected file to server? Ihave searched a solution but...

P.S. Sorry for bad English

It can't be done directly form Unity (at least not as far as I know), so you'll need to call the appropriate native operating system implementation using PInvoke, which will be different for each platform. You can probably get this to work on Windows by using PInvoke to call GetOpenFileName, but I don't know the equivalent for that on other OSs, if any.

It's not bad at all so far

 

But it is in C++ and how I can connect it to my project?

 

You can call methods defined in native DLLs from C# code using Platform Invocation (P/Invoke). You have to declare the method and its signature in C# code, then you call it like any regular static method.

Pinvoke.net has an example of how to do just that for GetOpenFileName (link).

 

Thanks. Are you not sure that it will work on all platforms? I have a multi-platform project.

 

It will only work on Windows because it's using Windows specific features. You'll have to find the equivalent in OS X and any flavor of Linus you might be targeting.

 

Please explain this - i'm so noob

 

That links included in my first and second posts have all the explanation and examples you'll need. All you need is to do some reading and to apply a tiny bit of effort.

Good luck.

 

Hello,

I made a Asset to use the Native File Browser from Windows and Mac in Unity at runtime, it's available on the Asset Store: https://www.assetstore.unity3d.com/en/#!/content/68064

I've been searching for a way to do that for more than a year... and finally found how to do it
