system.invalidoperationexception: 'standardout has not been redirected or the process hasn't started yet.'

To fix this issue, you can ensure that the process is running before trying to read its output, and also make sure that you are reading the output before the process exits.

using (Process process = new Process())
{
    process.StartInfo.FileName = "your_program.exe";
    process.Start();

    // Wait for the process to start
    while (!process.HasExited && !process.StandardOutput.EndOfStream)
    {
        // Read the output
        string output = process.StandardOutput.ReadLine();
        Console.WriteLine(output);
    }
}
