Help On @ Dates Comparision

Hi,

Try below code :

 DateTime date1 = new DateTime(2009, 8, 1, 12, 0, 1);

            DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);

            int result = DateTime.Compare(date1, date2);

            string val;



            if (result < 0)

                val = "is less than";

            else if (result == 0)

                val = "is the same time as";

            else

                val = "is greater than";

Console.WriteLine("{0} {1} {2}", date1, val, date2);

OR 
 

You can check the condition like below also.

if (DateTime.Compare(date1, date2) < 0) 

            { 

                Console.WriteLine("second date is larger than the first date"); 

            }

            else if (DateTime.Compare(date1, date2) == 0) 

            { 

                Console.WriteLine("second date is same as first date"); 

            } 

            else 

            { 

                Console.WriteLine("second date is smaller than the first date"); 

            }

Instead of date1 and date2 you can use calender value.

Suppose we have two TextBox Which Id's are txtStartDate and txtEndDate

string frmdt = txtStartDate.Text;
string todt = txtEndDate.Text;
FromDate=string.empty;
ToDate =string.empty;
int Datediff = 0;
int diff = 0;
//For this use the namespace System.Globalization;
FromDate = Convert.ToDateTime(frmdt, c).ToString("dd-MMM-yyyy", DateTimeFormatInfo.InvariantInfo);
ToDate = Convert.ToDateTime(todt, c).ToString("dd-MMM-yyyy", DateTimeFormatInfo.InvariantInfo);

//your answer in start here

//Code for date difference
DateTime dt2 = Convert.ToDateTime(ToDate);
DateTime dt1 = Convert.ToDateTime(FromDate);

Datediff = DateTime.Compare(dt1, dt2);
TimeSpan diff1 = dt2.Subtract(dt1);
diff = Convert.ToInt32(diff1.Days);

if(diff<=100)
respsoe.write("hellow");
