// Compiler Error! Cannot access the private class.

OuterClass.PrivateInnerClass inner2;

inner2 = new OuterClass.PrivateInnerClass();

}

To make use of this concept within our employees example, assume we have now nested the

BenefitPackage directly within the Employee class type:

partial class Employee

{

public class BenefitPackage

{

// Assume we have other members that represent

// 401K plans, dental/health benefits, and so on.

public double ComputePayDeduction()

{

return 125.0;

}

}

...

}

The nesting process can be as “deep” as you require. For example, assume we wish to create

an enumeration named BenefitPackageLevel, which documents the various benefit levels an

employee may choose. To programmatically enforce the tight connection between Employee,

BenefitPackage, and BenefitPackageLevel, we could nest the enumeration as follows:
