Generate ED25519 keys for ssh connection with Bouncy Castle c#

Question

I have to generate che keys in ED25519 for SSH connection. I'm able to create the public and the private keys but not the key for ssh. Is there anyone who can help me? Below my C# code.

Thanks

IAsymmetricCipherKeyPairGenerator gen;
KeyGenerationParameters param;
gen = new Ed25519KeyPairGenerator();
param = new Ed25519KeyGenerationParameters(new SecureRandom());
gen.Init(param);
var keyPair = gen.GenerateKeyPair();

TextWriter textWriter = new StringWriter();
PemWriter pemWriter = new PemWriter(textWriter);
pemWriter.WriteObject(keyPair.Private);
pemWriter.Writer.Flush();
                 
var privateKeyParam = keyPair.Private;

textWriter = new StringWriter();
pemWriter = new PemWriter(textWriter);
pemWriter.WriteObject(keyPair.Public);
pemWriter.Writer.Flush();

result.PrivateKey = textWriter.ToString();
result.PublicKey = textWriter.ToString();

Maybe try using this library SshKeyGenerator
