WebMay 31, 2024 · That's just an assertion, though, not an exception, because the C# language standard guarantees that the shift amount will be masked, such that only the lower 5 bits will be used (resulting in a value from 0 to 31). This means that the language protects you from the undefined behavior you would get in C by trying to shift by too many places.

"WebAn addendum to Marc Gravell and Vilx-'s answer: Your flagged enum shouldn't specify the amount for "All", it should just include your existing values. This goes for any calculated values. [Flags] public enum Time { None = 0, Current = 1, Past = 2, Future = 4, All = Current Past Future } Note that Vilx- removed the use of Hexadecimal for values. " - Bit shifting in c#

The last two operators to work with bit masks are the bitwise shifts. Taken a number, they literally shift its bits right (>>) or left (<<). If you have a decimal number, let’s say “1” and you shift it of one position to the left, you’ll have “10”. Another shift and you’ll get “100”.
