Contoh

Contoh kode berikut menunjukkan pembuatan , menetapkan nilai yang HttpClientConnectionsesuai untuk unduhan, lalu memanggil DownloadFile. Nilai properti memerlukan penggantian dengan nilai yang valid untuk aplikasi Anda.

const string svcName = "Test_WebService";  
string wsdlFile = Directory.GetCurrentDirectory() + @"\WebSvceTask_wsdl.wsdl";  

//create HTTP connection  
ConnectionManager httpConn = pkg.Connections.Add("HTTP");  
HttpClientConnection clientConn = new HttpClientConnection(httpConn.AcquireConnection(null));  
clientConn.UseProxy = true;  
clientConn.ProxyURL = @"http://yourproxy";  
clientConn.BypassProxyOnLocal = true;  
clientConn.ServerURL = yourURL;  

TaskHost th = (TaskHost)pkg.Executables.Add ("STOCK:WebServiceTask");  
WebServiceTask task = (WebServiceTask)th.InnerObject ;  

task.Connection = httpConn.Name;  
task.ServiceName = svcName;  
task.OutputType = DTSOutputType.Variable;  
task.OutputLocation = "output";  

clientConn.DownloadFile(wsdlFile, false);  
task.WsdlFile = wsdlFile;  

const String svcName = "Test_WebService"  
Dim wsdlFile As String =  Directory.GetCurrentDirectory() + "\WebSvceTask_wsdl.wsdl"   

'create HTTP connection  
Dim httpConn As ConnectionManager =  pkg.Connections.Add("HTTP")

Dim th As TaskHost = CType(pkg.Executables.Add("STOCK:WebServiceTask"), TaskHost)  
Dim task As WebServiceTask = CType(th.InnerObject, WebServiceTask)  

task.Connection = httpConn.Name
