 送信側

using System.IO;
using System.Threading;
public class FileWrite
{
  private static Mutex mut = new Mutex(false,"mut");
  private const string FILE_NAME = "hoge.txt";
  
  public static void Main(string[] args)
  {
 while(true)
   {

  //1.処理
  Thread.Sleep(1000);
  //2.ロック
  mut.WaitOne();
  //3.書き込み
  DateTime d = DateTime.Now;
  StreamWriter sw = new StreamWriter(FILE_NAME);
  sw.WriteLine(d.ToString());
  sw.Close();
  //4.ロックの開放
  mut.ReleaseMutex();
   }
