示例

下面的代码示例将从对象 RSAParameters 创建的关键信息导入到对象 RSACryptoServiceProvider 中。

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())
        {
        //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 RSA As 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.
        Dim RSAParams As RSAParameters = RSA.ExportParameters(False)

        'Create another RSACryptoServiceProvider object.
        Using RSA2 As New RSACryptoServiceProvider()

            'Import the key information from the other 
            'RSACryptoServiceProvider object.  
            RSA2.ImportParameters(RSAParams)
        End Using
    End Using

Catch e As CryptographicException
    'Catch this exception in case the encryption did
    'not succeed.
    Console.WriteLine(e.Message)
End Try
