Solution 2

Firstly you need to check the correct operator for equality. The expression

C#

if (time1=time2)

will assign the value of time2 to time1. You need to use the correct operator:

C#

if (time1 == time2)

Secondly, make use of the DateTime Struct (System) | Microsoft Docs[^] which contains methods, operators and properties to solve the majority of issues.

Apart from the assignment, in C# it will also give a compilation error since if expects a boolean value—that will work just fine in C++ based on the resulting value.

You are correct. I wonder why some of these posters are so afraid to try anything.

Just to add to the other answers, comparing Time values is not just an equality test: DateTime values are stored as a number of ticks since a particular point in time, and a tick is one hundred nanoseconds or one ten-millionth of a second - so comparing the time part of a date time will only be equal if the two times match to the 100 nanosecond point, which is a very short window. That's why most comparisons are not equality tests, they are greater than or equal to checks - the first instance that is over the minimum is the one that signals something to happen.
