將JAVA代碼KeyStore.getInstance轉換爲c＃

Question

我試圖將以下代碼轉換爲JAVA代碼爲C#以獲得ECPrivateKey。

private static ECPrivateKey loadPrivateKey(String pkcs12Filename) throws KeyStoreException, NoSuchProviderException, IOException, NoSuchAlgorithmException, CertificateException, UnrecoverableKeyException { 
    KeyStore keystore = KeyStore.getInstance("PKCS12", "BC"); 
    keystore.load(new FileInputStream(pkcs12Filename), "".toCharArray()); 
    assert keystore.size() == 1 : "wrong number of entries in keychain"; 
    Enumeration<String> aliases = keystore.aliases(); 
    String alias = null; 
    while (aliases.hasMoreElements()) { 
     alias = aliases.nextElement(); 
    } 
    return (ECPrivateKey) keystore.getKey(alias, null); 
}

這是代碼，我得到了這個輸出。

private void GetPrivateKeyFromP12(string path, string passWord) 
     { 
      //this.mKeyStoreEntities = PKCSUtils.extractEntities(privateKeyFilePath, privateKeyPassword); 
      /** 
      * Java has a minimum requirement for keystore password lengths. Utilities like KeyChain will 
      * allow you to specify less but then you will receive an obscure java error when trying to 
      * load the keystore. Check for it here and throw a meaningful error 
      */ 

      //X509Certificate certificate; 
      //ECPrivateKey privateKey; 

      using (StreamReader reader = new StreamReader(path)) 
      { 
       var fs = reader.BaseStream; 
       GetMerchantIdentifierField(fs); 

       fs.Position = 0; 
       GetPrivateKey(fs, passWord); 
      } 
     } 

     private void GetPrivateKey(Stream fs, string passWord) 
     { 
      Pkcs12Store store = new Pkcs12Store(fs, passWord.ToCharArray()); 

      foreach (string n in store.Aliases) 
      { 
       if (store.IsKeyEntry(n)) 
       { 
        AsymmetricKeyEntry asymmetricKey = store.GetKey(n); 

        if (asymmetricKey.Key.IsPrivate) 
        { 
         this.merchantPrivateKey = asymmetricKey.Key as ECPrivateKeyParameters; 
        } 
       } 
      } 
     }
