How to Save Your Computer's Startup History in C#

Learn how to save the history of when your computer started.

Let's write a simple program that will run automatically when your computer starts and will log the startup time in a text file.

 

Step 1: Create a simple Console application in C# and write the following code in the main method. Here we're appending current date time to a text file.

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace autologin
{
class Program
{
static void Main(string[] args)
{
File.AppendAllText(@"C:\logintime.txt", Environment.NewLine);
File.AppendAllText(@"C:\logintime.txt", "Your Login Time is : " + DateTime.Now.ToString());
}
}
}

Step 2: Build your application and get the exe file.

 

Step 3: Goto Control Panel->Sheduled task->Add sheduled Task->Next>Browse

 

Step 4: Browse your exe file that we just created in the previous step.
