Deserializing complex objects
I'm trying to use C# to connect to a SOAP server but having problems receving complex objects as return values. Here is the code:
First is my proxy:
[System.Web.Services.WebServiceBindingAttribute(Name="urn:ItemManager",Namespace="urn:Configuration")]
public class Configuration: SoapHttpClientProtocol
{
public Configuration()
{
this.Url = "http://localhost:7001/soap/servlet/rpcrouter";
}
[SoapDocumentMethodAttribute
("",RequestNamespace="urn:Configuration",ResponseNamespace="urn:Configuration",Use=
System.Web.Services.Description.SoapBindingUse.Encoded, ParameterStyle=SoapParameterStyle.Wrapped)]
public SiteConfig getSiteConfig()
{
object [] results = this.Invoke("getSiteConfig", new object[] {});
SiteConfig site = (SiteConfig)results[0];
return site;
}
}
My complex object:
public class SiteConfig
{
public int numRouters;
public int numSwitches;
}
Test client:
public class Test
{
public static void Main(string[] args)
{
Configuration config = new Configuration();
SiteConfig site = config.getSiteConfig();
Console.WriteLine(site.numRouters+"");
}
}
The problem I am getting is I get a "System.NullReferenceException: Object reference not set to an instance of an object." on the line Console.WriteLine(site.numRouters+""); in the Test client.
I've been looking at the SOAP messages and they seem to be working find. The response from the server looks like:
10
20
Any help would be great!
