How to read data from ExampleInternalsTelemetryOutput in real time

Hi guys, I´m developing a telemetry plugin following the sample. I haven't any problems to compile it and extract data to a text file, but I don't know how to read this file in real time by another aplication created by me in c#,

The idea is read this txt and resend data to an arduino project, but my c# aplication crashed because the txt file is already in use by the dll, here is a sample code:

Code:

while (true)
{
   string[] lines;

   Application.DoEvents();
                
   lines = System.IO.File.ReadAllLines(@"C:\Program Files (x86)\Steam\steamapps\common\rFactor 2\ExampleInternalsTelemetryOutput.txt");

   label1.Text = lines[5];
}

I'm bloqued at this point, any help is welcome.

Thanks.
