使用模量和指数的C＃中的RSA / ECB / PKCS1填充解密

我有一个来自Java服务器的加密值。我需要解密它。服务的文档为我提供了以下解密算法，提供程序将向我发送“ m”和“ e”值：

Java代码：

private  String RSA_Decryption(String encryptedData) 
        throws InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException,     IOException, IllegalBlockSizeException, BadPaddingException, GeneralSecurityException 
{
    BigInteger m = new BigInteger("verylongnumber1");
    BigInteger e = new BigInteger("verylongnumber2");

    RSAPrivateKeySpec keySpec = new RSAPrivateKeySpec(m, e);
    KeyFactory fact = KeyFactory.getInstance("RSA");
    PrivateKey privateKey = fact.generatePrivate(keySpec);

    Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
    cipher.init(Cipher.DECRYPT_MODE, privateKey);
    byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedData);
    byte[] decValue = cipher.doFinal(decordedValue);
    String decryptedValue = new String(decValue, "UTF-8");

    return decryptedValue;     
}

我需要在C＃中进行转换。到目前为止，我尝试了以下C＃代码（使用.NET的BigInteger类）：

string m = "verylongnumber1";
string e = "verylongnumber2";

RSAParameters info = new RSAParameters();
var modulus = BigInteger.Parse(m).ToByteArray();
if (modulus.Length == 129) Array.Resize(ref modulus, 128); // it gives me 129 characters, the last being 0

var exponent = BigInteger.Parse(e).ToByteArray();

info.Modulus = modulus.Reverse().ToArray();
info.D = exponent.Reverse().ToArray();

var encryptedData = Convert.FromBase64String(@"gEQwzXpaARzC2pz9ahiyji8G/K9xecMzh6qi7hMmih4kR4hBwwjfcX83lNet91/hzHX9if1XwAe7/fO5xgXR8qLY+sZu9mj+iXiaSgYyQO3VyxcMD6q/wiVBXpOCX/LmG6qCVbFgn6LZvvcx9fUjVEn3FJFpqUhQh9PvNjmg8ks=");

var decryptedValue = this.Decrypt(encryptedData, info);
string decryptedBarcode = Encoding.Default.GetString(decryptedValue);

byte[] decryptedBytes;
using (RSACryptoServiceProvider rsa1 = new RSACryptoServiceProvider())
{
    rsa1.ImportParameters(info); // throws exception with "Bad data" message
    decryptedBytes = rsa1.Decrypt(encryptedData, false);
}

但是，当我想在rsa1实例中导入keyInfo时，出现“ Bad Data”消息异常。

我也尝试过：

• 设置info.Exponent而不是info.D
• 使用Chew Keong提供的BigInteger类和getBytes方法获取模数和指数的字节（还要在info.Exponent和info.D中设置数组，带和不带反向）。

一切都导致带有“错误数据”消息的相同异常。

谁能帮我翻译成C＃等价的Java代码吗？
