推荐答案

只需使用HTTPwebRequest和webresponse class

Simply use the HTTPwebRequest and webresponse  class

                        Dim wbRq As HttpWebRequest = DirectCast(WebRequest.Create(targetUrl), HttpWebRequest)
                        wbRq.Timeout = 2000
                        Try
                            Dim wbRs As HttpWebResponse = DirectCast(wbRq.GetResponse(), HttpWebResponse)
                            Dim wbHCol As WebHeaderCollection = wbRs.Headers
                            For y As Integer = 0 To wbHCol.Count - 1
                                Dim header As String = wbHCol.GetKey(y)
                                Dim values As String() = wbHCol.GetValues(header)
                                If values.Length > 0 Then
                                    Select Case header.ToLower
                                        Case "content-type"
                                            theUrlContentType = values(0)
                                        Case "content-length"
                                            theUrlFileSize = values(0)
                                    End Select
                                End If
                            Next
                            wbRs.Close()
