Compare date only and find the difference

Vignesh Kumar

Hi,

I have a string and say for ex: 30-10-2016 in a string. Now how can I compare this date with today's date only and find the difference.

I am unable to use TimeSpan too because I 'm unable to get date only using datetime.

Todays date would be 27-10-2016

I need to find the difference between these two dates 30-10-2016 - 27-10-2016.

Accepted answer
string strdt="31/10/2016";
DateTime dt=DateTime.ParseExact(strdt, "dd/MM/yyyy", CultureInfo.InvariantCulture);
DateTime today = System.DateTime.Now;
int days = Convert.ToInt32((dt-today).TotalDays);
Console.WriteLine(days);
Console.ReadLine();

Use like this .i have already done.
usingSystem;
usingSystem.Net.NetworkInformation;
usingSystem.Net;
usingSystem.Net.Sockets;
usingSystem.Text.RegularExpressions;
namespaceExample
{
classProgram
{
staticvoidMain()
{
strings1="WhenyouarewritingservercodeyoucanneverbesurewhattheIPaddressyouseeisrefereeingto.Infactsomeuserslikeitthisway.";
strings2="WhenyouarewrtingservercodeyucannnneverbesurewhattheIPaddressyouseeisreferingto.Infactsomeuserslikeitthisway";
string[]tempArr1=s1.Split('');
string[]tempArr2=s2.Split('');
intcounter=0;
for(inti=0;i
{
if(tempArr1[i]!=tempArr2[i])
{
Console.WriteLine(tempArr1[i]+","+tempArr2[i]);
counter++;
}
}
Console.WriteLine("TotalModifiedWord::"+counter);
Console.ReadLine();
}
}
}

1. DateTimeFirstDate=Convert.ToDateTime("30-10-2016");
2. DateTimeSecondDate=DateTime.Today;
3. TimeSpanFirstMethodDays=SecondDate-FirstDate;
4. TimeSpanSecondMethodDays=SecondDate.Subtract(FirstDate);
5. intThirdMethodDays=Convert.ToInt16((SecondDate-FirstDate).TotalDays);
6. Console.WriteLine("Method 1: " + FirstMethodDays.ToString());
  Console.WriteLine("Method 2: " + SecondMethodDays.ToString());
  Console.WriteLine("Method 3: " + ThirdMethodDays.ToString());

I would want to do it in c#.

select DATEDIFF(day,convert(datetime,'30-11-2016',104),getdate())

This will give you the difference in days

If you want month or year replace day with month or year

Compare date only and find the difference
