How to test webservice with "out" params

[redsss]

I have a webservice with a method that uses "out" parameters to return data to the client.

When a client calls up the WSDL for the webservice and clicks on the method, it says "The test form is only available for methods with primitive types or arrays of primitive types as parameters."

Is there a way to enable the user to test this webservice, without me having to develop a special page for this purpose?

What's the type of the parameter? The message is saying it's not one of the supported types.

Its a string type. The WSDL works if the parameter is a byval, which can only be used to pass a value TO the webservice, but this method is used to get a value FROM the webservice, hence the param is an "out" param of type string.

That should work, as string is one of the fundamental datatypes used by SOAP.

I wonder what I'm doing wrong?

To experiment, I created another simple web service in VSNET 1.1, and created a simple ConvertTemperature webservice (which is the simple walkthrough in the help file).

The WSDL screen enabled me to test it from there, then I simple added an extra string parameter to the method and I get the same error:

The test form is only available for methods with primitive types or arrays of primitive types as parameters

The only change I made from the example was changing the method signature as follows:

public double ConvertTemperature(double dFahrenheit, out string mystring )

And I initialize mystring in the method. Any ideas?

Just so you know... you can't modify a reference item on a webservice. You have to pass the value and then set the value again when you submit the data.
