Problem with Nusoap & c#

[BOB Le Bricoleur]

Hi,

I have a small web service written in PHP with NuSOAP which describes a
type "Categorie" and a function "GetCategories()".

I'm trying to access it with a C# application.

Here is the generated code where the error occurs:
-------------------------------------------------------------------
public Categorie[] GetCategories() {
object[] results = this.Invoke("GetCategories", new object[0]); //OK
return ((Categorie[])(results[0])); //ERR
}
-------------------------------------------------------------------
I get an error at runtime:
"System.InvalidCastException", can't cast an object of type "Categorie"
to an object of type "Categorie" !!

The invoke method works fine, all the data is in the results array.

Thanks for your help.

Hi Bob,

For the cast to succeed both array must have the same number of dimensions
ant there must be an implicit or explicit conversion from the source element
type to the target element type.
You could use just one of the overloaded Array.Copy() methods. Looking at
you code I see
"return ((Categorie[])(results[0]));". Are you sure that you have array of
Categorie in first array - result[0] element?

Hi Bob,

type to the target element type.
You could use just one of the overloaded Array.Copy() methods. Looking at you
code I see

I get the same error messages with Array.Copy()

"return ((Categorie[])(results[0]));". Are you sure that you have array of
Categorie in first array - result[0] element?

I am pretty sure; here is what the debugger gives for "results[0]":

results[0]:{Dimensions:[3]}
[0]:{ModuleAstuces.localhost.Categorie}
[1]:{ModuleAstuces.localhost.Categorie}
[2]:{ModuleAstuces.localhost.Categorie}
The code was generated by visual studio 2005, it should work without
modifying it. This is weird..
