Get Lock And Unlock Information Of The System Using C#

Steps

1. Create 2 console applications (one for lock and other for unlock)
2. Write code to log lock and unlock time in a text file.
3. Schedule both the applications using task scheduler

Create 2 Console Applications (One For Lock And Other For Unlock)

1. Lock - to capture system lock time in the text file
2. Unlock – to capture system unlock time in text file

Write Code To Log Lock And Unlock Time In Text File

using System;
using System.IO;

namespace Unlock {
  class Program {
    static void Main(string[] args) {
      File.AppendAllText(@ "C:\test\info.txt", "Unlock time is " + DateTime.Now.ToString() + Environment.NewLine);
    }
  }
}

using System;
using System.IO;

namespace Lock {
  class Program {
    static void Main(string[] args) {
      File.AppendAllText(@ "C:\test\info.txt", "Lock time is " + DateTime.Now.ToString() + Environment.NewLine);
    }
  }
}

10. Finally close the task scheduler ‘Create task’ window.

1. ‘Name’ in the ‘General’ tab will be ‘Unlock’ (we can give any name here).
2. While creating a new trigger, the value of ‘Begin the task’ would be ‘On workstation Unlock’.
3. In ‘Actions’ tab, unlock.exe would be selected.
