using System; using System.CodeDom; using System.CodeDom.Compiler; using System.Web.Services; using System.Web.Services.Description; using System.Web.Services.Discovery; using System.Xml; using System.Xml.Serialization; public class Test { public static void Main () { // Read in a WSDL service description. string url = "http://www.contoso.com/Example/WebService.asmx?WSDL"; XmlTextReader reader = new XmlTextReader(url); ServiceDescription wsdl = ServiceDescription.Read(reader); // Create a WSDL collection. DiscoveryClientDocumentCollection wsdlCollection = new DiscoveryClientDocumentCollection(); wsdlCollection.Add(url, wsdl); // Define the parameters needed to create web references. CodeNamespace proxyNamespace = new CodeNamespace("ExampleNamespace"); string baseUrl = "http://www.contoso.com"; string protocolName = "Soap12"; // Create some web references. WebReference reference1 = new WebReference( wsdlCollection, proxyNamespace, protocolName, "UrlKey1", baseUrl); WebReference reference2 = new WebReference( wsdlCollection, proxyNamespace, protocolName, "UrlKey2", baseUrl); WebReference reference3 = new WebReference( wsdlCollection, proxyNamespace, protocolName, "UrlKey3", baseUrl); // Create a web reference collection. WebReferenceCollection references = new WebReferenceCollection(); references.Add(reference1); references.Add(reference2); // Confirm that the references were inserted. Console.WriteLine("The collection contains {0} references.", references.Count); // Insert another reference into the collection. references.Insert(2, reference3); // Print the index of the inserted reference. int index = references.IndexOf(reference3); Console.WriteLine("The index of reference3 is {0}.", index); // Remove the inserted reference from the collection. references.Remove(reference3); // Determine if the collection contains reference3. if (references.Contains(reference3)) { Console.WriteLine("The collection contains reference3."); } else { Console.WriteLine("The collection does not contain reference3."); } // Print the URL key of the first reference in the collection. Console.WriteLine( "The URL key of the first reference in the collection is {0}.", references[0].AppSettingUrlKey); // Copy the collection to an array leaving the first array slot empty. WebReference[] referenceArray = new WebReference[3]; references.CopyTo(referenceArray, 1); Console.WriteLine( "The URL key of the first reference in the array is {0}.", referenceArray[1].AppSettingUrlKey); } }
