Problems registering SoapExtension programmatically.... Help!

[fcaico@gmail.com]

I have a .NET 1.1 C# application that needs to connect to a custom web
service for authentication and system access. This web service uses a
custom SOAP header for security purposes.

In the past this has been a non issue because I simply registered a
SoapHeaderExten sion in the application's App.Config file.

Now, however, we have need of using this C# client code in an assembly
which doesn't have access to an app.config file (long story). So I
wanted to be able to register this SoapHeaderExten sion
programmaticall y at runtime.

I found this reference: http://weblogs.asp.net/cweyer/archiv.../07/22929.aspx
which tells how to do it, but this code isn't working for me at all.

Basically in my code I use:

protected void InjectSoapExten sions()
{
Assembly assBase;
Type webServiceConfi g;
object currentProp;
PropertyInfo propInfo;
object[] value;
Type myType;
object[] objArray;
object myObj;
FieldInfo myField;

try
{
assBase = typeof(SoapExte nsionAttribute) .Assembly;

webServiceConfi g = assBase.GetType (
"System.Web.Ser vices.Configura tion.WebService sConfiguration" );

if (webServiceConf ig == null)
{
throw new Exception("Unab le to get Web Service Config assembly");
}

*** currentProp =
webServiceConfi g.GetProperty(" Current").GetVa lue(null, null);
propInfo = webServiceConfi g.GetProperty(" SoapExtensionTy pes");
value = (object[])propInfo.GetVa lue(currentProp , null);
myType = value.GetType() .GetElementType ();
objArray = (object[])Array.CreateIn stance(myType,
(int)value.Leng th + 1);

Array.Copy(valu e, objArray, (int)value.Leng th);

myObj = Activator.Creat eInstance(myTyp e);
myField = myType.GetField ("Type");

myField.SetValu e(myObj, typeof(PediHead erExtension));
objArray[(int)objArray.L ength - 1] = myObj;
propInfo.SetVal ue(currentProp, objArray, null);
}
catch (Exception ex)
{
throw ex;
}

}

The code fails at the assignment to currentProp because the retrieved
type "webServiceConf ig" has no current or SoapExtension properties (in
fact it has NO properties - I wrote a program to reflect through the
type and its pretty bare).

Any ideas? I'm getting pretty desperate here.

Thanks
