'Usage
Dim instance As FileWebResponse
Dim value As WebHeaderCollection

value = instance.Headers

/** @property */

public override function get Headers () : WebHeaderCollection

Property Value

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.
