如何在Android中以编程方式从设备检索已安装的证书(Xamarin)

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

using Java.Security;
using Java.Security.Cert;
using Java.IO;
using Android.Content;

public List<string> GetInstalledCertificates(Context context)
{
    List<string> certificates = new List<string>();

    try
    {
        KeyStore keyStore = KeyStore.GetInstance("AndroidCAStore");
        keyStore.Load(null, null);

        Enumeration aliases = keyStore.Aliases();
        while (aliases.HasMoreElements)
        {
            string alias = (string)aliases.NextElement();
            X509Certificate cert = (X509Certificate)keyStore.GetCertificate(alias);

            certificates.Add(cert.SubjectDN.ToString());
        }
    }
    catch (Exception e)
    {
        // 处理异常
    }

    return certificates;
}

List<string> installedCertificates = GetInstalledCertificates(this);

foreach (string certificate in installedCertificates)
{
    Console.WriteLine(certificate);
}
