The provided code snippet contains a syntax issue and cannot execute as intended because the chaining of lastDay = lastFriday = lastFriday.AddDays(-1) assumes that lastFriday is already defined and initialized. If it is not, the code will result in a compilation or runtime error.

However, if we assume that lastFriday has been properly declared and initialized as a DateTime object earlier in the code, here’s what the code intends to do:

1. The code assigns the value of lastFriday.AddDays(-1) to both the lastDay and lastFriday variables.
2. lastFriday.AddDays(-1) subtracts one day from the lastFriday variable, resulting in a new DateTime that is one day earlier than the value of lastFriday.
3. Both lastDay and lastFriday will hold the same DateTime value, which is the previous day relative to the original value of lastFriday.

For this to work, prior code must have initialized lastFriday to a valid DateTime. For example:

DateTime lastFriday = DateTime.Now; // Initialize lastFriday
var lastDay = lastFriday = lastFriday.AddDays(-1);

Final Explanation:

The code:

• Subtracts one day from the lastFriday variable using .AddDays(-1).
• Assigns the resulting date to both lastFriday and lastDay.

If the code snippet is part of a larger context, ensure that variables are initialized properly to avoid runtime errors.
