Using << notation for flags C# with Example

The left-shift operator (<<) can be used in flag enum declarations to ensure that each flag has exactly one 1 in 
binary representation, as flags should. 
This also helps to improve readability of large enums with plenty of flags in them. 
[Flags] 
public enum MyEnum 
{ 
None = 0, 
Flag1 = 1 << 0, 
Flag2 = 1 << 1, 
Flag3 = 1 << 2, 
Flag4 = 1 << 3, 
Flag5 = 1 << 4, 
... 
Flag31 = 1 << 30 
} 
It is obvious now that MyEnum contains proper flags only and not any messy stuff like Flag30 = 1073741822 (or 
111111111111111111111111111110 in binary) which is inappropriate.
