Hi Sachi You want to increase the time only one time because the example you have given of double it is a loop which increase the value at every loop. I believe you want to increase the time by half hour only one ime. DateTime class provide a method AddHour which can be used to increase the time by half hour. As in the examble below I am increasing the Current time value by Half an hour. Response.Write( DateTime .Now.AddHours(.5).ToString()); Hope this help

Sachiyou have to assign it to that variable again like this. DateTime time = DateTime.Now; MessageBox.Show(time.ToShortTimeString()); time=time.AddHours(0.5);//this will return time.we have to assign it to var MessageBox.Show(time.ToShortTimeString()); for your code.it will be DateTime time = DateTime.Now; textBox1.Text = time.AddHours(0.5).ToShortTimeString();

thanks suchit for your kind reply suchit but the addhours function is not working. I have written the following code private void Form6_Load( object sender EventArgs e) { DateTime time = DateTime .Now; time.AddHours(0.5); textBox1.Text = time.ToString(); //DateTime time1 = time; //time.AddHours(0.5); //textBox2.Text = time.ToString(); } Here the textbox is displaying the current time. The thing is I want to display the time like 09:30:00 Am in first row of a datagridview followed by 10:00:00 Am in the next row and so on( I want to add half an hour for the previous time) thanks

Hi Sachi Please try to use intellisense and you could find many functions there for such tasks... anyways here is a sample code which could help you: class Program { static void Main(string[] args) { DateTime time = DateTime.Now; Console.WriteLine(Current time is : {0} time); Console.WriteLine(Time after half hour will be:{0} time.AddHours(0.5)); Console.Read(); } }
