如果您在NET 3.5.1上,您可以选择应用汇总修补程序并应用注册表编辑来告诉.NET使用系统默认值。 More details here
如果您需要使用.NET 4.5 for TLS 1.2 & 1.1支持,并且至少需要在Windows Server 2008 R2上运行。

我使用VS 2008与.net 3.5.30729.4926。我所要做的就是:
添加进口:
Imports System.Security.Authentication
Imports System.Net
这添加到我的代码(C#):
public const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
public const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12
VB.net版本:
Const _Tls12 As SslProtocols = DirectCast(&HC00, SslProtocols)
Const Tls12 As SecurityProtocolType = DirectCast(_Tls12, SecurityProtocolType)
ServicePointManager.SecurityProtocol = Tls12
Dim wbrq As HttpWebRequest
Dim wbrs As HttpWebResponse
Dim sw As StreamWriter
Dim sr As StreamReader
Dim strResult As String
'Create a new HttpWebRequest object.
wbrq = WebRequest.Create(strURL)
wbrq.Method = "POST"
wbrq.ContentLength = DataString.Length
wbrq.ContentType = "application/x-www-form-urlencoded"
'upload data
sw = New StreamWriter(wbrq.GetRequestStream)
sw.Write(DataString)
sw.Close()
'get response
wbrs = wbrq.GetResponse
sr = New StreamReader(wbrs.GetResponseStream)
strResult = sr.ReadToEnd.Trim
sr.Close()
