Ok, I had actually previously figured out that I had to write a simple web
method that returns an instance of the StringKeyStringValue type in order
for a corresponding stub definition to be included in References.cs
In the webservices newsgroup, it was suggested to me that I modify
References.cs to delete this stub definition and include the following line
of code:
using UtilityStorageLibrary;
"UtilityStorageLibrary" is the namespace used in my custom class library
that contains the definition of the StringKeyStringValue type
The logic is that any StringKeyStringValue objects returned by web-methods
will be received by the proxy class and on deserialization will be converted
into instances of the local StringKeyStringValue type.
I made these changes, and I no longer receive any compile-time or run-time
errors ...
However,
Object[] array = WebReference1.WebService1.WebMethod1();
StringKeyStringValue sksv = (StringKeyStringValue) array[0];
String s1 = sksv.Key;
String s2 = sksv.Value;
reveals that sksv.Key and sksv.Value are both null
So, apparently sending across an array of instances of a custom type is a
bit more tricky than sending across a single instance of a custom type.
