I wrote a code to send file as below:
Dim objXMLDoc As New XmlDocument
objXMLDoc.Load("C:\Inetpub\wwwroot\XMLSchema_Test\XML\1773777.xml")
Dim blnResponse As Boolean
Dim objURI As Uri = New Uri("https://172.16.17.2/XMLSchema_Tests1/Web%20Forms/frmXML_Receive.aspx")
Dim objWR As HttpWebRequest = HttpWebRequest.Create(objURI)
blnResponse = objWR.HaveResponse
Dim strXML As String = objXMLDoc.OuterXml
objWR.Method = "POST"
Dim encoding As New System.Text.ASCIIEncoding
Dim btXMLLen() As Byte = encoding.UTF8.GetBytes(strXML)
objWR.ContentLength = btXMLLen.Length
objWR.KeepAlive = False
Dim streamToSend As IO.Stream = objWR.GetRequestStream
Dim strMessage As String
Dim strStatus As String
Dim blnConnect As Boolean
Try
