FileWebResponse.Headers Property

Gets a collection of header name/value pairs associated with the response.

Namespace:  System.Net
Assembly:  System (in System.dll)
'Declaration
Public Overrides ReadOnly Property Headers As WebHeaderCollection

Property Value

Type: System.Net.WebHeaderCollection
A 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 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)

        ' Display all Headers present in the response received from the Uri.
        Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The following headers were received in the response: ")
        ' Headers property is a WebHeaderCollection. Using it's properties to traverse the collection and display each header. 
        Dim i As Integer 

        While i < myFileWebResponse.Headers.Count
            Console.WriteLine(ControlChars.Cr + "Header Name:{0}, Header value :{1}", myFileWebResponse.Headers.Keys(i), myFileWebResponse.Headers(i))
            i = i + 1
        End While
        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)
    End Try
