Generally speaking you don't need to do this. If you want to ensure space at some directory location you use the ReserveCost mechanism and let Windows figure out if there's enough room. Windows already computes the size of the feature for space checking, and ReserveCost lets you change it. Why reinvent it?
If you want to try it yourself, MsiGetFeatureCost is perhaps what you'd call, but you'd have to sequence it after InstallValidate. I hesitate to even suggest this because the sequencing is critical, I doubt you can make it work in the UI sequence, and using sample code that tells you to call actions like InstallValidate yourself is likely to be giving you a shovel for the hole you'll be digging yourself into. So as is common with many MSI questions: Advice: Don't do it - use ReserveCost. Technically (mostly) accurate answer: MsiGetFeatureCost (but I think you'll regret it).

What I want is size(XX MB). I want this number to assign some variable(int reqdiskspace) for checking disk space logic. Presently I added manually the variable reqdiskspace=YY(for ex int reqdiskspace=100) In future if size of feature increases then I again I have to modify manually the reqdiskspace. So is it possible to assign the same to property, so that I can get the value through msigetproperty.
