A Multiple Inheritance Issue related to "Property Class"

I have several property classes in which some of them are overlapping, so I decided to use "inheritance" to create Parent-child relationship.

However, it only works for one-to-one inheritance in c#, how can it be done with "Multiple Inheritance".

For example,

Parent <--- Child A + Child B + Child C

4 Different Property Class
====================================
Property Class 1 - Parent
Property Class 2 - Child A
Property Class 3 - Child B
Property Class 4 - Child C
====================================

Please help
