try
{
Uri^ fileUrl = gcnew Uri( String::Concat( "file://", url ) );
// Create a 'FileWebrequest' Object* with the specified Uri.
FileWebRequest^ myFileWebRequest = (FileWebRequest^)( WebRequest::Create( fileUrl ) );
// Send the 'fileWebRequest' and wait for response.
FileWebResponse^ myFileWebResponse = (FileWebResponse^)( myFileWebRequest->GetResponse() );
// Print the ContentLength and ContentType properties received as headers in the response Object*.
Console::WriteLine( "\nContent length : {0}, Content Type : {1}", myFileWebResponse->ContentLength, myFileWebResponse->ContentType );
// Release resources of response Object*.
myFileWebResponse->Close();
}
catch ( WebException^ e )
{
Console::WriteLine( "\r\nWebException thrown. The Reason for failure is : {0}", e->Status );
}
catch ( Exception^ e )
{
Console::WriteLine( "\nThe following Exception was raised : {0}", e->Message );
}
}
public static void GetPage(String url)
{
try
{
Uri fileUrl = new Uri("file://"+url);
// Create a 'FileWebrequest' object with the specified Uri.
FileWebRequest myFileWebRequest = (FileWebRequest)WebRequest.Create(fileUrl);
// Send the 'fileWebRequest' and wait for response.
FileWebResponse myFileWebResponse = (FileWebResponse)myFileWebRequest.GetResponse();
// Print the ContentLength and ContentType properties received as headers in the response object.
Console.WriteLine("\nContent length :{0}, Content Type : {1}",myFileWebResponse.ContentLength,myFileWebResponse.ContentType);
// Release resources of response object.
myFileWebResponse.Close();
}
catch(WebException e)
{
Console.WriteLine("\r\nWebException thrown. The Reason for failure is : {0}",e.Status);
}
catch(Exception e)
{
Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
}
}
Public Shared Sub GetPage(url As [String])
Try
Dim fileUrl As New Uri("file://" + url)
' Create a 'FileWebrequest' object with the specified Uri
Dim myFileWebRequest As FileWebRequest = CType(WebRequest.Create(fileUrl), FileWebRequest)
' Send the 'fileWebRequest' and wait for response.
Dim myFileWebResponse As FileWebResponse = CType(myFileWebRequest.GetResponse(), FileWebResponse)
' The ContentLength and ContentType received as headers in the response object are also exposed as properties.
' These provide information about the length and type of the entity body in the response.
Console.WriteLine(ControlChars.Cr + "Content length :{0}, Content Type : {1}", myFileWebResponse.ContentLength, myFileWebResponse.ContentType)
myFileWebResponse.Close()
Catch e As WebException
Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The Reason for failure is : {0}", e.Status)
Catch e As Exception
Console.WriteLine(ControlChars.Cr + "The following exception was raised : {0}", e.Message)
