Checking whether website has certificate C#

Question

is there any way to check whether website has any certificate? I tried to do this with Selenium Web Driver but I had some difficulties. We want to automate navigation through several sites until we find one with certificate. Thanks in advance.

应该尝试使用https：//而不是http打开URL，并且如果未引发异常（例如，不是来自受信任的提供程序的证书），或者该页面不存在，则您的页面具有有效的SSL证书。
