Answer 1

Check an example:

// some date, used to show the month and year in Label1:
DateTime some_date = new DateTime( 2024, 9, 17 ); // 17-September-2024

// for Label2:
DateTime first_day = new DateTime( some_date.Year, some_date.Month, 1 ); // 1-September-2024

// for Label3:
DateTime last_day = first_day.AddMonths( 1 ).AddDays( -1 ); // 30-September-2024

Answer 2

Hi @RAVI,

You can refer to the following code:

 Label1.Text = "April-2024";
 DateTime date = Convert.ToDateTime(Label1.Text);
 var firstDayOfMonth = new DateTime(date.Year, date.Month, 1);
 Label2.Text = firstDayOfMonth.ToString("dd-MMM-yyyy");
 var lastDayOfMonth = firstDayOfMonth.AddMonths(1).AddDays(-1);
 Label3.Text = lastDayOfMonth.ToString("dd-MMM-yyyy");

Output:
