DiscoveryDocument Class
Represents a discovery document. This class cannot be inherited.
Assembly: System.Web.Services (in System.Web.Services.dll)
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; 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); } } }
