Get lock and unlock information of the system using C#

In this article, we will calculate lock and unlock time of the system in C#.

Steps

In this article, we will follow these 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)

First of all, create 2 console applications. Let us give some name to the application

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

In the program.cs write the following code

Unlock – Program.cs

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);
        }
    }
}

Lock – Program.cs

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);
        }
    }
}

Schedule both the applications using task scheduler

Now let us schedule both the applications using task scheduler. For lock

1. Open task scheduler.

2. Click on ‘Create Task’

3. In the popup window, enter the name as ‘Lock’ in ‘General’ tab (we can give any name here).

Click to Enlarge

   4. Go to ‘Trigger’ tab.

   5. Click on the ‘New…’ button, another popup window appears.

   6. In the pop up window, select ‘Begin the task’ as ‘On workstation lock’ and click Ok.

   7. Go to ‘Actions’ tab.

   8. Click on ‘New…’ button. Another pop up window appears

   9. Browse the exe file of ‘Lock’ and click ok.

Click to Enlarge

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

For unlock, same process will be followed except these changes

   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.

Output

Now lock and unlock your system, you will get this output
