How to make a Windows Service that deletes file every 15 minutes with C#?

You need to track a start date time and then check the difference between the current time in a loop until it is greater than so many minutes.  

then reset the start time with current time and go back to a loop again.

You will need to sleep your thread during the looping to make sure it doesn't eat your processor up between cycles.

Here is some date math code I found that might help you.

DateTime startTime = DateTime.Now;

DateTime endTime = DateTime.Now.AddSeconds( 75 );

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
Console.WriteLine( "Time Difference (hours): " + span.Hours );
Console.WriteLine( "Time Difference (days): " + span.Days );

Hello,

actually I need a sample of the cs file that would show how I can call a method from a windows service cs file page. It does not have to be even delete file. Just a Windows service. I cannot figure out where to insert a method like "DeleteFile()" or "GetDataFromTable()". Should I insert a method, say that has to execute say every day or or every week at OnStart()? Would you please give me some code that shows where I will insert my method that will be executing say every day.
