Parameters
- parameters
- RSAParameters
The parameters for RSA.
Exceptions
The cryptographic service provider (CSP) cannot be acquired.

The parameters
parameter has missing fields.
Examples
The following code example imports key information created from an RSAParameters object into an RSACryptoServiceProvider object.
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())
{
//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.

Console.WriteLine(e.Message)
End Try
