First, sorry for my rusty english !

Before launching a process, I have to test if files are existing in a Sharepoint library.

My Microsoft environment (Visual Studio 2022) advise this:

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete. Use HttpClient instead.

I would like to have a function to use it like this:

If SharepointFileExist(strMyFile) then
else
endif

I try to use sample code I find in stackoveflow, but I can’t succeed…

For exemple, this code doesn’t work:

Private Function SharepointFileExist(ByVal strHost As String) As Boolean
 
    Try
        Dim request As WebRequest = WebRequest.Create(strHost)
        request.UseDefaultCredentials = True
        request.PreAuthenticate = True
        Dim response As WebResponse = request.GetResponse()
        Call MsgBox("SUCCESS!!!")
        Return True
    Catch ex As Exception
        Call MsgBox("ERROR: " & ex.ToString)
        Return False
    End Try
 
End Function

Can you give me the full content I need to achieve function SharepointFileExist() ?

Thank you in advance,
