问题
I created a text file named Write.txt in the Documents folder in a Xamarin.iOS app. After that I was able to read its content to the console.
var documents =
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "Write.txt");
File.WriteAllText(filename, "Write this text into a file");
var text = File.ReadAllText(filename);
Console.WriteLine(text); // prints out correctly
The problem is, that I can't found this file on the iPhone simulator's Files app. There is no Documents folder anywhere, and I don't get any results if I search for the filename.
(Yes, I'm new in iOS, so sorry if the question is stupid :) )

See Building Great Document-based Apps in iOS 11.
If you want to see it in the files app, you’ll want to set the following value in your Info.plist:
- “Supports Document Browser” (
UISupportsDocumentBrowser)
Or
- “Application supports iTunes file sharing” (
UIFileSharingEnabled); and - “Supports opening documents in place” (
LSSupportsOpeningDocumentsInPlace)

I just run your code and it all works well on my side. The file you written to was successfully opened. I guess you might have some wrong step when opening the folder, let me show you how to do it:
1.I run your code and then print the file path(the filename in your code), on my side it is:
/Users/myName/Library/Developer/CoreSimulator/Devices/0F06FD18-4307-4102-8A30-5EB017A4BD26/data/Containers/Data/Application/20A0294B-36C5-484F-8BD1-B69B977BA378/Documents/Write.txt
2.Go to your mac --> select Finder --> Then open the Go menu --> Click Go to Folder
3.Paste your path to the text box:
4.Click Go and you will see the file:
Some folders are hidden in your system so you can't see them when search for the filename. Feel free to ask me if you have any question.
