i trying construct object derives different object, before calling base constructor make few argument validation.

public fuelmotorcycle(string owner) : base(owner) {     argumentvalidation(owner); }

no, @ least not directly.

but can use small workaround have static method takes argument, validates , returns if it's valid or throws exception if it's not:

private static string argumentvalidate(string owner) {     if (/* validation logic owner */) return owner;     else throw new yourinvalidargumentexception(); } 

then have derived class constructor pass arguments through method before giving them base constructor:

public fuelmotorcycle(string owner) : base(argumentvalidate(owner)) { }
