使用SSIS从TLS1.2站点下载文件

Question

Our current process was working fine and was able to download files until the site decided to switch to TLS 1.2 protocol. Now, our file downloads no longer work.

Our existing solution is based on this vb.net solution and this does not seem to handle TLS downloads. I can see the file, connect to it but cant download it. Is there a way to handle this in either VB.net or C#?

Answer 1

This worked for me:

    Imports System.Net

    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12

    Dim webclient As New WebClient

    webclient.BaseAddress = Dts.Variables("ServerURL").Value
    WebClient.Credentials = New NetworkCredential(Dts.Variables("ServerUsername").Value.ToString, Dts.Variables("ServerPassword").Value.ToString)

    Dim filename As String = "C:\Temp\Sample.txt"
    WebClient.DownloadFile(Dts.Variables("ServerURL").Value, filename)
