Creating my first soap request

Question

I'm fairly new to web services/api calls

I've been given a wsdl for development.

http://bogus.com/SM/7/ServiceCatalogAPI.wsdl

I've added a service reference to the wsdl using Visual Studio 2010 c# .net 4.0

I've been given a username/password (basic authentication)

I'm looking for guidance on how to do the request. Am I on the right path?

I have the following, but I'm receiving 'Cannot implicitly convert type 'string' to 'SM9.ServiceReference1.StringType'

protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
        ServiceReference1.CreateCartRequest createCart = new ServiceReference1.CreateCartRequest();

        string result = createCart.model.instance.BriefDescription = "Testing SM9";

        Label1.Text = result.ToString();
    }
    catch (System.Exception ex)
    {
        Label1.Text = ex.Message;
    }
}

I don't see any actual calls to the webservice, where did you get your response from? — Hanno
Hi Hanno, the request and response were included in documentation. I'm trying to figure out how to make my first call. — user2379544

It looks like the BriefDescription is not of type string. Try something like this:

string result = createCart.model.instance.BriefDescription = new StringType("Testing SM9");

or

 string result = createCart.model.instance.BriefDescription = new StringType() { Value = "Testing SM9" };

(Sorry I don't know what properties "StringType" actually has).
