NameDescription
System_CAPS_pubfieldSystem_CAPS_staticNamespace

Namespace of the discovery XML element of a discovery document.

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.

using System.Xml;
using System.IO;
using System.Web.Services.Discovery;
using System.Collections;

public class DiscoveryDocument_Example
{
   static void Main()
   {
      try
      {
         // Create an object of the 'DiscoveryDocument'.
         DiscoveryDocument myDiscoveryDocument = new DiscoveryDocument();

         // Create an XmlTextReader with the sample file.
         XmlTextReader myXmlTextReader = new 
            XmlTextReader( "http://localhost/example_cs.disco" );

         // Read the given XmlTextReader.
         myDiscoveryDocument = DiscoveryDocument.Read( myXmlTextReader );

         // Write the DiscoveryDocument into the 'TextWriter'.
         FileStream myFileStream = new 
                  FileStream( "log.txt", FileMode.OpenOrCreate, FileAccess.Write );
         StreamWriter myStreamWriter = new StreamWriter( myFileStream );
         myDiscoveryDocument.Write( myStreamWriter );

         myStreamWriter.Flush();  
         myStreamWriter.Close(); 

         // Display the contents of the DiscoveryDocument onto the console.
         FileStream myFileStream1 = new
                        FileStream( "log.txt", FileMode.OpenOrCreate, FileAccess.Read );
         StreamReader myStreamReader = 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() );
         }
         myStreamReader.Close();
      }
      catch( Exception e )
      {
         Console.WriteLine( "Exception raised : {0}", e.Message);
      }
   }
