Baseline response (no ZPI)
To calculate a deadline 7 business days from now, skipping Saturday and Sunday, you can use the following C# code:
```csharp
using System;
public class Program
{
public static void Main()
{
DateTime deadline = GetDeadline(7);
Console.WriteLine(deadline);
}
public static DateTime GetDeadline(int businessDays)
{
DateTime currentDate = DateTime.UtcNow;
int daysAdded = 0;
while (daysAdded < businessDays)
{
currentDate = currentDate.AddDays(1);
// Check if the day is a weekday (not Saturday or Sunday)
if (currentDate.DayOfWeek != DayOfWeek.Saturday && currentDate.DayOfWeek != DayOfWeek.Sunday)
{
daysAdded++;
}
}
return currentDate;
}
}
```
In this code:
1. We start with the current UTC date and time using `DateTime.UtcNow`.
2. We use a `while` loop to keep adding days until we have added the required number of business days.
3. Inside the loop, we check if the current day is a weekday (not Saturday or Sunday) using the `DayOfWeek` property.
4. If it is a weekday, we increment the `daysAdded` counter.
5. Once we have added the required number of business days, we return the resulting date and time.
Note that this code does not account for holidays or other non-business days. If you need to exclude those as well, you would need to add additional logic to check for specific dates or use a library that provides holiday information.
Enhanced response (with ZPI)
```csharp
using System;
public class DeadlineCalculator
{
public static DateTime CalculateDeadline()
{
var utcNow = DateTime.UtcNow;
var daysToAdd = 0;
var deadline = utcNow;
while (daysToAdd < 7)
{
deadline = deadline.AddDays(1);
if (deadline.DayOfWeek != DayOfWeek.Saturday && deadline.DayOfWeek != DayOfWeek.Sunday)
{
daysToAdd++;
}
}
return deadline;
}
public static void Main(string[] args)
{
var deadline = CalculateDeadline();
Console.WriteLine(deadline);
}
}
```
This code calculates the deadline by continuously adding days to the current UTC time until it has added 7 business days, skipping Saturdays and Sundays. The `Main` method demonstrates how to use the `CalculateDeadline` method to compute and print the deadline.
