c# - C＃の証明書ストアから証明書のリストを取得します

Question

安全なアプリケーションの場合、ダイアログで証明書を選択する必要があります。C＃を使用して証明書ストアまたはその一部（storeLocation="Local Machine"およびなど）にアクセスし、そこからすべての証明書のコレクションを取得するにはどうすればよいですか？storeName="My"よろしくお願いします。

Answer 1

X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

store.Open(OpenFlags.ReadOnly);

foreach (X509Certificate2 certificate in store.Certificates){
    //TODO's
}

Answer 2

これを試して：

//using System.Security.Cryptography.X509Certificates;
public static X509Certificate2 selectCert(StoreName store, StoreLocation location, string windowTitle, string windowMsg)
{

    X509Certificate2 certSelected = null;
    X509Store x509Store = new X509Store(store, location);
    x509Store.Open(OpenFlags.ReadOnly);

    X509Certificate2Collection col = x509Store.Certificates;
    X509Certificate2Collection sel = X509Certificate2UI.SelectFromCollection(col, windowTitle, windowMsg, X509SelectionFlag.SingleSelection);

    if (sel.Count > 0)
    {
        X509Certificate2Enumerator en = sel.GetEnumerator();
        en.MoveNext();
        certSelected = en.Current;
    }

    x509Store.Close();

    return certSelected;
}

Answer 3

The simplest way to do that is by opening the certificate store you want and then using X509Certificate2UI.

var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
var selectedCertificate = X509Certificate2UI.SelectFromCollection(
    store.Certificates, 
    "Title", 
    "MSG", 
    X509SelectionFlag.SingleSelection);

Answer 4

はい --X509Store.Certificatesプロパティは X.509 証明書ストアのスナップショットを返します。
