| Description |
The Create method should really have been named CreateFile so as to distinguish from the Create constructor (as is the case in DirectoryInfo.CreateDirectory).
It creates the file whose name was specified in the PathString value, returning a FileStream object allowing access to the file.
Optionally, the BufferSize may be specified.
|
| | Notes | Important : you must prefix Create with an & to distinguish from the Create keyword.
Important : you should assign the result of the Create to a variable and close that stream before using other methods such as CopyTo. Otherwise you will get an IO Exception to say that the file is in use!

// List files in the current folder again
Console.WriteLine;
Files := System.IO.Directory.GetFiles(Directory.GetCurrentDirectory);
for i := 0 to Length(Files)-1 do
Console.WriteLine(System.IO.Path.GetFileName(Files[i]));
// Clean up - delete the new file
System.IO.File.Delete(Path);
Console.Readline;
end.
