Q. Can I inherit two difference classes to partial classes? Following is the whole scenario of this question:
I have two classes XYZ and ABC and two partial classes of class myClass now is it possible:
partial class myClass : XYZ
{
}
partial class myClass : ABC
{
}
Ans: This question I have asked in RSystems, Noida and I am sharing hereunder with you :

The main reason is in C# we cant do the following:
class myClass : XYZ, …
