Examples

This example creates an HttpWebRequest and queries for a response. This example then checks whether the entity requested had been modified any time today.

Uri^ myUri = gcnew Uri( url );
// Creates an HttpWebRequest for the specified URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
if ( myHttpWebResponse->StatusCode == HttpStatusCode::OK )
{
   Console::WriteLine( "\r\nRequest succeeded and the requested information is in the response , Description : {0}",
      myHttpWebResponse->StatusDescription );
}
DateTime today = DateTime::Now;
// Uses the LastModified property to compare with today's date.
if ( DateTime::Compare( today, myHttpWebResponse->LastModified ) == 0 )
{
   Console::WriteLine( "\nThe requested URI entity was modified today" );
}      
else if ( DateTime::Compare( today, myHttpWebResponse->LastModified ) == 1 )
{
   Console::WriteLine( "\nThe requested URI was last modified on: {0}",
      myHttpWebResponse->LastModified );
}
// Releases the resources of the response.
myHttpWebResponse->Close();
        Uri myUri = new Uri(url);
// Creates an HttpWebRequest for the specified URL. 
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(myUri); 
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
	Console.WriteLine("\r\nRequest succeeded and the requested information is in the response , Description : {0}",
						myHttpWebResponse.StatusDescription);
DateTime today = DateTime.Now;
// Uses the LastModified property to compare with today's date.
if (DateTime.Compare(today,myHttpWebResponse.LastModified) == 0)
	Console.WriteLine("\nThe requested URI entity was modified today");
else
	if (DateTime.Compare(today,myHttpWebResponse.LastModified) == 1)
		Console.WriteLine("\nThe requested URI was last modified on:{0}",
							myHttpWebResponse.LastModified);
// Releases the resources of the response.
myHttpWebResponse.Close(); 
Dim myUri As New Uri(url)
' Creates an HttpWebRequest for the specified URL.
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(myUri), HttpWebRequest)
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
If myHttpWebResponse.StatusCode = HttpStatusCode.OK Then
    Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "Request succeeded and the requested information is in the response , Description : {0}", myHttpWebResponse.StatusDescription)
End If
Dim today As DateTime = DateTime.Now
' Uses the LastModified property to compare with today's date.
If DateTime.Compare(today, myHttpWebResponse.LastModified) = 0 Then
    Console.WriteLine(ControlChars.Cr + "The requested URI entity was modified today")
Else
    If DateTime.Compare(today, myHttpWebResponse.LastModified) =  1 Then
        Console.WriteLine(ControlChars.Cr + "The requested Uri was last modified on:{0}", myHttpWebResponse.LastModified)
    End If
End If
' Releases the resources of the response.
myHttpWebResponse.Close()

Remarks

The LastModified property contains the value of the Last-Modified header received with the response. The date and time are assumed to be local time.
