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()
