Simplification of conditions

[okarpov]

The idea is the following - this condition:

if (Key == "954553" || Key == "954571") { Width = 1280; Height = 720; }

most probably can be written as:

if (Key == "954553" || == "954571") { Width = 1280; Height = 720; }

especially in case of long variables like: classA.PropertyB == "string" || classA.PropertyB == "string2"

Thx

You can use pattern matching: Key is "xxx" or "yyy"

probably i missed a lot of latest improvements in C# ))
could you please provide code example?

Your example could be written as:

if (Key is "954553" or "954571") { Width = 1280; Height = 720; }

but is not 'is' used for type comparison and not value comparison? or this is a special case for conditions?

[bernd5]

Yes, in the past it was used for type checks - later it was extended for pattern matching. The old type checks are now type patterns (which have an optional designation now)
