I have an ASP.Net calendar feature which allows users to add events and
configure whether or not they repeat at various frequencies (i.e, daily,
weekly, monthly, Sat/Sun, etc.). What I'm looking for is some C# code that
will calculate a date of "Every Other Week" based on a starting date and
ending date.
Example: If a user enters an event dated October 3, 2005 and would like it
to repeat every other week until October 31, 2005, the code will return the
following dates:
October 3, 2005
October 17, 2005
October 31, 2005
Any help would be greatly appreciated.

I think its as simple as adding number of days to the datetime type as:
DateTime dt = new DateTime(2005, 10, 3);
dt=dt.AddDays(14);
now dt has 17th oct. You keep on adding days like that until the the end
date comes, like in a loop.
Hope that helps.

It's a bit more complex than that Ab. In order to determine how many dates
there are representing "Every other Week" starting on October 3, 2005 and
ending on October 31, 2005, you first have to figure out how many entries
there should be. In this case, there should be 3. A "for loop" is required
to loop through Oct 3 to Oct 31 and return either the number of days or
weeks. Example, the code below will insert the correct number of entries for
an event that repeated every day from Oct 3 to Oct 31 (intNumberofDays is
determined using TimeSpan):
if (EventFrequency == "Day")
{
for(int i = 0; i <= intNumberofDays; i++)
{
string strInsert = "INSERT INTO Events " +
"(EventStartDateTime, " +
"EventEndDateTime) VALUES " +
"('" + dtEventStartDateTime.AddDays(i) + "', " +
"'" + dtEventEndDateTime.AddDays(i) + "') ";
objConnection = new SqlConnection(dbPath);
objCommand = new SqlCommand(strInsert,objConnection);
objConnection.Open();
objCommand.ExecuteNonQuery();
objConnection.Close();
}
}
The problem I'm running into is substituting "intNumberofDays" with
"intNumberofWeeks" will return 5 weeks, where I really need it to return 3
weeks. "i" will then be 3 which I can plug into a revised SQL insert
statement and use "dtEventStartDateTime.AddWeeks(i)" to populate my database
with the 3 dates representing "Every Other Week" (Oct 3, Oct, 17, Oct 31).
Simply subtracting 2 weeks won't work since the duration of events entered
by users can change from entry to entry.

I think I've resolved my issue. The key was to divide "intNumberofWeeks" by
2. The following code seems to work fine...so far:
for(int i = 0; i <= intNumberofWeeks / 2; i++)
{
string strInsert = "INSERT INTO Events " +
"(EventStartDateTime, " +
"EventEndDateTime) VALUES " +
"('" + dtEventStartDateTime.AddDays(i * 14) + "', " +
"'" + dtEventEndDateTime.AddDays(i * 14) + "') ";
objConnection = new SqlConnection(dbPath);
objCommand = new SqlCommand(strInsert,objConnection);
objConnection.Open();
objCommand.ExecuteNonQuery();
objConnection.Close();
}

There's no need to care about the number of inserts you're doing at the time
you're calculating it (unless of course you have this constraint).
DateTime dt = startDate;
int frequency = 14;
int insertCount = 0;
int maxInserts = 100; //may not be necessary for you...
//begin tran
while( dt <= endDate && insertCount < maxInserts )
{
//insert dt into your date table
dt.AddDays( frequency );
insertCount++;
}
if( insertCount >= maxInserts )
{rollback tran}
else
{commit tran}
