ASP.NET: Consuming a PHP WSDL SOAP Webservice

After starting Visual Studio we create a new Visual Basic ASP.NET Web Application project:

After it opens up we right-click on the project name in the "Solution Explorer" and choose "Add Web Reference..."

Now we can enter the URL of the WSDL file 'http://customer-ws.tld/customer-ws_Customers.wsdl' and press 'Enter'. Visual Studio fetches all the information provided by the xml file and shows up all the data:

We enter a "Web reference name" (I choose 'WSDLWebService') and click on "Add Reference". Now we can see the entered Web Reference in the "Solution Explorer":

Now we right-click the Web Reference called "WSDLWebService" and choose "View in Object Window":

We can see here that Visual Studio has created all the objects and methods that the WSDL file announced.

So we go to the "Code Editor" of our Default.aspx by right-clicking the file in the "Solution Explorer" and enter the following lines:

Public Class _Default

    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim CallWebservice As New WSDLWebService.customer-ws_Customers

        Dim Cache As System.Net.CredentialCache = New System.Net.CredentialCache

        Dim vUserId As String

        vUserId = "1889941"

        Dim vCustomer() As WSDLWebService.Customer

        vCustomer = CallWebservice.getCustomers()

        Label1.Text = vCustomer.length

    End Sub

End Class

I have added a Label with the ID "Label1" with the "Designer" and the Toolbar to the Default-Page:

Now we can press debug and the Internet Explorer should pop up and display in the Label1 field the amount of Customers returned by the WebService.
