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.dll> #using <System.Web.Services.dll> using namespace System; using namespace System::Xml; using namespace System::IO; using namespace System::Web::Services::Discovery; using namespace System::Collections; int main() { try { // Create an Object* of the 'DiscoveryDocument'. DiscoveryDocument^ myDiscoveryDocument = gcnew DiscoveryDocument; // Create an XmlTextReader with the sample file. XmlTextReader^ myXmlTextReader = gcnew XmlTextReader( "http://localhost/example_cs.disco" ); // Read the given XmlTextReader. myDiscoveryDocument = DiscoveryDocument::Read( myXmlTextReader ); // Write the DiscoveryDocument into the 'TextWriter'. FileStream^ myFileStream = gcnew FileStream( "log.txt",FileMode::OpenOrCreate,FileAccess::Write ); StreamWriter^ myStreamWriter = gcnew StreamWriter( myFileStream ); myDiscoveryDocument->Write( myStreamWriter ); myStreamWriter->Flush(); myStreamWriter->Close(); // Display the contents of the DiscoveryDocument onto the console. FileStream^ myFileStream1 = gcnew FileStream( "log.txt",FileMode::OpenOrCreate,FileAccess::Read ); StreamReader^ myStreamReader = gcnew 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 ); } }
