C#中实现https的双向认证

1．  把浏览器中的证书导出为cer文件。

2.   代码如下：

using System;
using System.Net;
using System.IO;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Net.Security;

public partial class About : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
       // string url = "https://192.168.6.120/";
        ServicePointManager.ServerCertificateValidationCallback = RemoteCertificateValidationCallback;
        //Uri uri = new Uri("https://www.baifubao.com/");


        Uri uri = new Uri("https://192.168.6.120/");
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
        X509Certificate cer = new X509Certificate("F:\csharp2.cer");
        request.ClientCertificates.Add(cer);

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        string encoding = response.ContentEncoding;
        if (encoding == null || encoding.Length < 1)
        {
            encoding = "UTF-8"; //默认编码
        }
        StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
        Response.Write(reader.ReadToEnd());
        //Console.Write(reader.ReadToEnd());
        response.Close();
    }
    public static bool RemoteCertificateValidationCallback(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
    {
        if (sslPolicyErrors == SslPolicyErrors.None)
            return true;
        return false;
    }
}
