public interface SimplePrx : Ice.ObjectPrx
{
    void op();
    void op(Ice.OptionalContext __context = new Ice.OptionalContext());
}

...

For each operation in the interface, the proxy class has a member function of the same name. For the preceding example, we find that the operation op has been mapped to the method op. The optional parameter __context is for use by the Ice run time to store information about how to deliver a request. You normally do not need to use it. (We examine the __context parameter in detail in Request Contexts. The parameter is also used by IceStorm.)

...

A value of null denotes the null proxy. The null proxy is a dedicated value that indicates that a proxy points "nowhere" (denotes no object).

Interface Inheritance in C#

Inheritance relationships among Slice interfaces are maintained in the generated C# classes. For example:

module M
{
    interface A { ... }
    interface B { ... }
    interface C extends A, B { ... }
}

The generated code for CPrx reflects the inheritance hierarchy:

namespace M
{
    public interface CPrx : APrx, BPrx
    {
        ...
    }
}

Given a proxy for C, a client can invoke any operation defined for interface C, as well as any operation inherited from C's base interfaces.
