In this article, you will learn how to runs windows service that periodically and once a day at specific time using C#
Windows Service that runs periodically at regular intervals and as well as once a day at specific time of day.
The Windows service will support two modes
1. Daily mode: Windows Service will execute a task at specific time of day.
2. Interval mode: Windows Service execute a task at regular intervals after some delay.
Add the AppSettings to the App.Config file

</startup>

<add key ="IntervalMinutes" value ="1"/>
<add key ="ScheduledTime" value ="15:45"/>

Windows Service that runs periodically and once a day at specific time using C#
C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application.
C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming
and will also take you through various advanced concepts related to C# programming language.
C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc.
For example...
using System;
namespace MinifyCode
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello Minify Code");
}
}
}
Output: Hello Minify Code
In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object.

Server Object
The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs.
Methods and Properties of the Server object
The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET.
