Hi guys;

I want to generate end date excluding weekends.

I have tried this but didn't give me expected result:

VB

<pre>    <WebMethod()> _
    Public Shared Function GenerateEndDate(startDate As String, numberOfDays As Integer) As String
        If IsDate(startDate) Then
            ' generate end date
            Dim endDate As Date = CDate(startDate).AddDays(GetNoOfWorkingDays(CDate(startDate), numberOfDays))  'DateAdd(DateInterval.Day, numberOfDays - 1, CDate(startDate))
            ' get number of working days

            Return endDate.ToShortDateString
        End If
        Return "N/A"
    End Function

    Private Shared Function GetNoOfWorkingDays(ByVal startDate As Date, ByVal noOfDays As Int32) As Int32
        Dim counter As Integer = 0
        Dim endDate As DateTime = DateAdd(DateInterval.Day, noOfDays, startDate)
        While startDate < endDate
            startDate = startDate.AddDays(1)
            Dim dayNoInWeek = CInt(startDate.DayOfWeek)
            If dayNoInWeek <> 0 Then
                If dayNoInWeek <> 6 Then
                    counter += 1
                End If
            End If
        End While

        Return noOfDays + counter
    End Function

This assumes only dates are compared, not times, and work week is Monday-Friday

C#

private int NumberOfWorkDays(DateTime start, int numberOfDays)
{
    int workDays = 0;

    DateTime end = start.AddDays(numberOfDays);

    while(start != end)
    {
        if(start.DayOfWeek != DayOfWeek.Saturday && start.DayOfWeek != DayOfWeek.Sunday)
        {
            workDays++;
        }

        start = start.AddDays(1);
    }

    return workDays;
}
