arraylist check if date in another array list [Resolved]

Hi,
try this Code

ArrayList list1 = new ArrayList(new DateTime[] { Convert.ToDateTime("2010-12-01"), Convert.ToDateTime("2010-12-11"), Convert.ToDateTime("2010-12-21") });

            ArrayList list2 = new ArrayList(new DateTime[] { Convert.ToDateTime("2010-12-01"), Convert.ToDateTime("2010-12-15"), Convert.ToDateTime("2010-12-22") });

            int CountofList1 = list1.Count;

            int CountofList2 = list2.Count;

            if (CountofList1 > CountofList2)

            {

                foreach (DateTime str in list1)

                {

                    if (!list2.Contains(str))

                    {

                        MessageBox.Show(Convert.ToString(str));

                    }

                }

            }

            else if (CountofList1 == CountofList2)

            {

                foreach (DateTime  str in list2)

                {

                    if (!list1.Contains(str))

                    {

                        MessageBox.Show(Convert.ToString(str));

                    }

                }

            }



            else

            {

                foreach (DateTime str in list2)

                {

                    if (!list1.Contains(str))

                    {

                        MessageBox.Show(Convert.ToString(str));

                    }

                }

            }

dtMeetingdate.Sort(); //1st Arraylist
currentdata.Sort(); //2nd Arraylist
int bcount = dtMeetingdate.Count;
int fcount = currentdata.Count;
if (bcount > fcount)
{

foreach (var item1 in dtMeetingdate)
{
foreach (var item2 in currentdata)
{
if (item1.ToString() == item2.ToString())
{
return true;
}
}
}
}
else
{

foreach (var item1 in currentdata)
{
foreach (var item2 in dtMeetingdate)
{
if (item1.ToString() == item2.ToString())
{
return true;
}
}
}
}

Hi,

You can directly use below method to check whether data is available in ArrayList
ArrayList.Contains("value");

Velkumar_In thanks for replying but i resolved it like this way


count = (from i in currdates.ToArray()
join j in dbdates.ToArray()
on i equals j
select new { ddate = i, cdate = j }).Count();
