System.IO.File get file created in iOS documents directory

I have an iOS native plugin that saves a file to the application documents directory. Upon successful completion of saving the file, I make a callback to unity with the filepath and check to see if the file exists.

I can confirm the file does exist in the iOS documents directory, as it is a video and I load the video natively and play it. However, in C# using System.IO.File, it does not seem to be able to find it.

Code (CSharp):

1. void HandleRecordingSavedEvent (bool isSuccessful, string outputDir)
2.     {
3.         Debug.Log("Event callback for saved: " + isSuccessful + " at " + outputDir);
4.  
5.         _recording = false;
6.         _endTime = Time.time;
7.  
8.         string[] pathComponents = outputDir.Split(new string[] { @"\/" }, System.StringSplitOptions.None);
9.         string fileName = pathComponents[pathComponents.Length - 1];
10.  
11.         string myGuess = Application.persistentDataPath + @"/" + fileName;
12.  
13.         Debug.Log("My Guess " + myGuess);
14.  
15.         if (File.Exists(myGuess))
16.             Debug.Log("I found her!");
17.         else
18.             Debug.Log("Cannot find");
19.     }

And in the console window when I run the application I get the following output

Can anyone spot something I am doing wrong?

 

I incorrectly assumed Mono would use and accept the same format that native iOS does.

Adding code along the same sort of thought process as this corrects the issue

Code (CSharp):

1.  
2. #ifUNITY_IOS
3.  
4. MatchregexMatch = Regex.Match(videoURL, "(?<=Documents)(.*)");
5.  
6. videoURL = Application.persistentDataPath + regexMatch.Value;
7. #else
8. //otherplatformsmayneedchanging
9. #endif
10.
