範例
下列程式代碼範例會將從 物件建立的 RSAParameters 索引鍵資訊匯入 RSACryptoServiceProvider 物件中。
try
{
//Create a new RSACryptoServiceProvider object.
RSACryptoServiceProvider^ RSA = gcnew RSACryptoServiceProvider;
//Export the key information to an RSAParameters object.
//Pass false to export the public key information or pass
//true to export public and private key information.
RSAParameters RSAParams = RSA->ExportParameters( false );
//Create another RSACryptoServiceProvider object.
RSACryptoServiceProvider^ RSA2 = gcnew RSACryptoServiceProvider;
//Import the key information from the other
//RSACryptoServiceProvider object.
RSA2->ImportParameters( RSAParams );
}
catch ( CryptographicException^ e )
{
//Catch this exception in case the encryption did
//not succeed.
Console::WriteLine( e->Message );
}
try
{
//Create a new RSACryptoServiceProvider object.
using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
{
//Export the key information to an RSAParameters object.
//Pass false to export the public key information or pass
//true to export public and private key information.
RSAParameters RSAParams = RSA.ExportParameters(false);
//Create another RSACryptoServiceProvider object.
using (RSACryptoServiceProvider RSA2 = new RSACryptoServiceProvider())

//RSACryptoServiceProvider object.

}
}
}

{
//Catch this exception in case the encryption did
//not succeed.
Console.WriteLine(e.Message);
