How can get today date only and time only not together?

To get a date 5 days later than today (ignoring time) you can use:

DateTime dt = DateTime.Today.AddDays(5);
Label2.Text = dt.ToString("dd/MM/yyyy");

for only date try this:

string date=DateTime.Now.ToString("dd/MM/yyyy");
 Label1.Text = date;//here showing it in a label


for only tme:

string time = DateTime.Now.ToString("HH:mm:ss tt");
 Label1.Text = time;//here showing it in a label
