I can start Mathematica from C#, but the CubeOfCubes.nb argument cannot be found (The file "CubeOfCubes.nb" could not be found.).
private void BtnKubus_Click(object sender, RoutedEventArgs e)
{
Process P = new Process();
P.StartInfo.FileName = "C:\\Programme/Wolfram Research/Mathematica/12.2/Mathematica.exe/";
P.StartInfo.Arguments = "CubeOfCubes.nb";
P.Start();
CubeOfCubes.nb is in the same directory as Mathematica.exe. How do I have to proceed?
