这里要用到的ShowBootIni.exe程序集的代码如下:

using System.Collections.Generic;
using System.Text;

            {
                // Create an instance of StreamReader to read from a file.
                // The using statement also closes the StreamReader.
                using (StreamReader sr = new StreamReader(Environment.ExpandEnvironmentVariables("%systemdrive%") + @"\boot.ini"))
                {
                    String line;

                    // Read and display lines from the file until the end of 
                    // the file is reached.
                    while ((line = sr.ReadLine()) != null)
                    {
                        Console.WriteLine(line);
                    }
                    sr.Close();
                }
            }
            catch (Exception e)
            {
                // Let the user know what went wrong.
                Console.WriteLine("The file could not be read:");
                Console.WriteLine(e.Message);
            }
        }
    }
}
