c# - 指定用于 WSHttpBinding 客户端连接的 SSL 协议(protocol)版本

Question

在通过 WSHttpBinding 使用 Web 服务时，是否可以指定要使用的 SSL 协议(protocol)版本？

我一直在使用跟踪日志来尝试确定为什么我使用客户端证书通过 SSL 调用 Web 服务失败。

最终日志记录显示警报 15 03 01 00 02 和警报代码 02 0A，这是一个 unexpected_error。我怀疑此错误是因为服务器无法处理我向其发送的 SSL 版本。

我有一个基于 PHP 的客户端，它使用相同的网络服务，我通过 cURL 指定 SSL 版本 3 (curl_setopt($ch, CURLOPT_SSLVERSION, 3);)。

版本可以设置如下:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3;
