How can I check if the current time is between in a time frame?

Question

I have a service that user can configure to run during \"off-peak\" hours. They have the ability to set the time frame that the service can run.

For Example:

Answer 1

DateTime t1;
t1 = DateTime.Now;

// loop inbetween start and end time      

if (t1>=start_time &&t1<=end_time) 

{
   //your code / action
}

//if you are using sql to get values 

start_time = Convert.ToDateTime(row.Cells[10].Text);
end_time = Convert.ToDateTime(row.Cells[11].Text);
//convert them to string or you will get some error!!!
