XML Web services discovery involves discovering the available XML Web services, given an URL. The URL typically points to a discovery document, which usually has a.disco file name extension. The discovery document, which is an XML document, contains references to information about the existance of XML Web services, such as a service description, XML Schema Definition (XSD) language schema, or another discovery document. This class represents the contents of the discovery document; where the References property contains a list of the references contained within the discovery document.
The following code example reads a discovery document from a file using the Read and writes it back out to file using the Write method.
Imports System Imports System.Xml Imports System.IO Imports System.Web.Services.Discovery Imports System.Collections Public Class DiscoveryDocument_Example Shared Sub Main() Try ' Create an object of the 'DiscoveryDocument'. Dim myDiscoveryDocument As New DiscoveryDocument() ' Create an XmlTextReader with the sample file. Dim myXmlTextReader As New XmlTextReader("http://localhost/example_vb.disco") ' Read the given XmlTextReader. myDiscoveryDocument = DiscoveryDocument.Read(myXmlTextReader) ' Write the DiscoveryDocument into the 'TextWriter'. Dim myFileStream As New FileStream("log.txt", FileMode.OpenOrCreate, FileAccess.Write) Dim myStreamWriter As New StreamWriter(myFileStream) myDiscoveryDocument.Write(myStreamWriter) myStreamWriter.Flush() myStreamWriter.Close() ' Display the contents of the DiscoveryDocument onto the console. Dim myFileStream1 As New FileStream("log.txt", FileMode.OpenOrCreate, FileAccess.Read) Dim myStreamReader As New StreamReader(myFileStream1) ' Set the file pointer to the begin. myStreamReader.BaseStream.Seek(0, SeekOrigin.Begin) Console.WriteLine("The contents of the DiscoveryDocument are-") While myStreamReader.Peek() > - 1 Console.WriteLine(myStreamReader.ReadLine()) End While myStreamReader.Close() Catch e As Exception Console.WriteLine("Exception raised : {0}", e.Message.ToString()) End Try End Sub 'Main End Class 'DiscoveryDocument_Example
