Question

Ok I need help if I have this code and I wanted to know if there was a way to detect if the number is greater than the one in the textbox?

if (textbox1.text == "2")
{
     //code
}

and I was wondering is there anyway to detect if the number is greater than that so say textbox1.text = "5" it is greater than 2 so therefore it does the code from the if command?

Answer 1

int value;
if (Int32.TryParse(textbox1.Text, out value))
{
   if (value > 2)
     // code
}
else
{
    // not a number in textbox
}

Sample for your real application:

TimeSpan timeOfDay = DateTime.Now.ToLocalTime().TimeOfDay;

if (8 < timeOfDay.Hours && timeOfDay.Hours < 16)
{
    // day
}
else
{
    // night
}

You can create extension method:

public static bool IsDayTime(this DateTime date)
{
    TimeSpan timeOfDay = date.TimeOfDay;
    return 8 < timeOfDay.Hours && timeOfDay.Hours < 16;
}

And use it this way:

var date = DateTime.Now.ToLocalTime();
var file = Path.Combine(Folder, date.IsDayTime() ? "Day.bmp" : "Night.bmp");
picThumbnail.ImageLocation = file;
picThumbnail.SizeMode = PictureBoxSizeMode.Zoom;
SystemParametersInfo(20, 0, file, 0x01 | 0x02);
var rkWallPaper = Registry.CurrentUser.OpenSubKey("Control Panel\\Desktop", true);
rkWallPaper.SetValue("WallpaperStyle", 2);
rkWallPaper.SetValue("TileWallpaper", 0);
rkWallPaper.Close();
