'Usage
Dim instance As HttpClientConnection
Dim fileName As String
Dim OverwriteDestination As Boolean
instance.DownloadFile(fileName, OverwriteDestination)
public void DownloadFile(
string fileName,
bool OverwriteDestination
)
public:
void DownloadFile(
String^ fileName,

OverwriteDestination:bool -> unit
public function DownloadFile(
fileName : String,
OverwriteDestination : boolean
)
Parameters
- fileName

Examples
The following code example shows the creation of an HttpClientConnection, sets appropriate values for the download, then calls DownloadFile. The value of the properties requires replacement with values that are valid for your application.
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 clientConn As HttpClientConnection = New HttpClientConnection(httpConn.AcquireConnection(Nothing))
clientConn.UseProxy = True
clientConn.ProxyURL = "http://yourproxy"
clientConn.BypassProxyOnLocal = True
clientConn.ServerURL = yourURL
Dim th As TaskHost = CType(pkg.Executables.Add("STOCK:WebServiceTask"), TaskHost)
Dim task As WebServiceTask = CType(th.InnerObject, WebServiceTask)
task.Connection = httpConn.Name
task.ServiceName = svcName
task.OutputType = DTSOutputType.Variable
task.OutputLocation = "output"
clientConn.DownloadFile(wsdlFile, False)
task.WsdlFile = wsdlFile
