问题描述
有谁知道如何基于来自 web浏览器控制SSL来打开证书信息屏幕？
Does anyone know how to open up the "Certificate Information" screen based on the SSL from the WebBrowser control?
推荐答案
这可以通过使用一类叫做 X509Certificate2UI 实现的。
This can be achieved by using a class called X509Certificate2UI.
为使这个类avalable给你，你需要添加一个引用 System.Security.dll
To make this class avalable to you, you need to add a reference to System.Security.dll
在 X509Certificate2UI 类有一个名为meyhod DisplayCertificate（）这需要一个 X509Certificate2 对象作为参数。当被调用时，此方法显示一个对话框，显示所有的证书信息，包括链接，完全一样的对话框，你会发现在IE浏览器。
In the X509Certificate2UI class you have a meyhod called DisplayCertificate() which takes an X509Certificate2 object as a parameter. When invoked, this method shows a dialog box displaying all cert information including chaining, exactly the same as the dialog box you will find in IE.
WebBrowser控件只能返回一个 X509证书然后可以传递到 X509Certificate2的构造类。
The webbrowser control can only return a X509Certificate which can then be passed into the constructor of the X509Certificate2 class.
所以，code看起来这样的：
So the code looks as such:
//includes on top
using System.Security;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
//Do webrequest to get info on secure site
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://securesite.com");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
response.Close();
//retrieve the ssl cert and assign it to an X509Certificate object
X509Certificate cert = request.ServicePoint.Certificate;
//convert the X509Certificate to an X509Certificate2 object by passing it into the constructor
X509Certificate2 cert2 = new X509Certificate2(cert);
//display the cert dialog box
X509Certificate2UI.DisplayCertificate(cert2);
