Assembly: System (in System.dll)
Property Value
Type: System.Net.WebHeaderCollectionA WebHeaderCollection that contains the header name/value pairs associated with the response.
The Headers property contains two name/value pairs, one for content length and one for content type, both of which are also exposed as properties, ContentLength and ContentType.
The following example uses the Headers property to retrieve the name/value pairs associated with the response.
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(); // Display all Headers present in the response received from the Uri. Console.WriteLine("\r\nThe following headers were received in the response:"); // Display each header and the key of the response object. for(int i=0; i < myFileWebResponse.Headers.Count; ++i) Console.WriteLine("\nHeader Name:{0}, Header value :{1}",myFileWebResponse.Headers.Keys[i], myFileWebResponse.Headers[i]); 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); } }
void GetPage(String* url) {
try {
Uri* fileUrl = new Uri(String::Concat(S"file://", url));
// Create a 'FileWebrequest' Object* with the specified Uri .
FileWebRequest* myFileWebRequest =
dynamic_cast<FileWebRequest*>(WebRequest::Create(fileUrl));
// Send the 'fileWebRequest' and wait for response.
FileWebResponse* myFileWebResponse =
dynamic_cast<FileWebResponse*>(myFileWebRequest->GetResponse());
// Display all Headers present in the response received from the Uri.
Console::WriteLine(S"\r\nThe following headers were received in the response:");
// Display each header and the key of the response Object*.
for (int i=0; i < myFileWebResponse->Headers->Count; ++i)
Console::WriteLine(S"\nHeader Name: {0}, Header value : {1}",
myFileWebResponse->Headers->Keys->Item[i],
myFileWebResponse->Headers->Item[i]);
myFileWebResponse->Close();
} catch (WebException* e) {
Console::WriteLine(S"\r\nWebException thrown.The Reason for failure is : {0}",
__box( e->Status));
} catch (Exception* e) {
Console::WriteLine(S"\nThe following Exception was raised : {0}",
e->Message);
