System.IO can be used to create a file:

var storage = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
var file1 = Path.Combine (storage, "Download", "test.txt");

System.IO.FileStream fs = System.IO.File.Create (file1);
fs.Close ();

However, it cannot be used to delete a file:

System.IO.File.Delete (file1);

Fails with:
Access to the path "/mnt/sdcard/..." is denied.

You can successfully delete the file using Java APIs:

var fs2 = new Java.IO.File (file1);
fs2.Delete ();

Note you need the "android.permission.WRITE_EXTERNAL_STORAGE" permission in
your manifest.
