How would I calculate time left in winform?
Hi any ideas on how to calculate time left to a specific hour,
i.e. we start countdown with
if currentTime >= TimeSpan.Parse("06:40") && currentTime <= TimeSpan.Parse("07:25")
and then we parse current hour and end hour (in this example 7:25) and make a label show how many minutes and seconds are left.
I've tried making something with substracting timespan now and end time timespan but it didn't work out at all.
EDIT: The main idea is something like this, but I can't get it to work by using TimeSpan neither DateTime
string myTime;
void timer()
{
var endTime = DateTime.Parse(myTime);
var beginTime = DateTime.Now.TimeOfDay;
}
private void timer1_Tick(object sender, EventArgs e)
{
var endTime = DateTime.Parse(myTime);
var beginTime = DateTime.Now.TimeOfDay;
TimeSpan difference = endTime - beginTime;
TimeSpan currentTime = DateTime.Now.TimeOfDay;
if (currentTime >= TimeSpan.Parse("06:40") && currentTime <= TimeSpan.Parse("07:25"))
{
label5.Text = "0";
myTime = "07:25";
timer();
label6.Text = difference;
}
}

Can you show us compilable code (like having an if statement with parentheses)? I'm assuming thatcurrentTimeis a DateTime. If so, you can't compare a DateTime with a TimeSpan. What are you really trying to do? In general, you should work with DateTime and TimeSpan quantities (initializing them with constructors or static methods (other than.Parse), and then convert them to strings only when you need to display them to users

It is entirely unclear what you are asking about. Of course subtracting two TimeSpans will work; it will produce another TimeSpan indicating the delta between the two TimeSpans you subtracted. Please provide a Minimal, Complete, and Verifiable example demonstrating the problem you have.

Use DateTime instead of TimeSpan when parsing points in time. TimeSpan is for durations. The difference between two points in time (DateTime) will be a duration (TimeSpan).
var end = DateTime.Parse("21:00");
var now = DateTime.Now; // Could also be some other point in time
TimeSpan timeLeft = end-now;
Console.WriteLine(timeLeft);
Result:
00:24:25.8581440
If you don't like the seconds and fractions of seconds, you can use a custom format, e.g.
Console.WriteLine(timeLeft.ToString("hh\:mm"));

That seems to work but the problem is that I need to display time left as text of a label and not just in console, and visual studio won't let me convert TimeSpan to string.
