And this:

// Create multipart form data
string boundary = "STARTBOUND_" + Guid.NewGuid().ToString() + "_ENDBOUND";

AS2 over http C# Send message with signature to mendelson server.
Now for Sign data I have this code:
public byte[] SignData(byte[] data, string p12FilePath, string p12Password)
{
byte[] contentHash;
using (SHA256 sha256 = SHA256.Create())
{
contentHash = sha256.ComputeHash(data);
}
// Load the signer's certificate
X509Certificate2 signerCert = new X509Certificate2(p12FilePath, p12Password);
// Create a SignedCms object
SignedCms signedCms = new SignedCms(SubjectIdentifierType.IssuerAndSerialNumber, new ContentInfo(contentHash), false);
// Create a CmsSigner object
CmsSigner signer = new CmsSigner(signerCert);
signer.DigestAlgorithm = new Oid("2.16.840.1.101.3.4.2.1");
// Sign the hash of the content
signedCms.ComputeSignature(signer, false);
// Encode the signed CMS message
byte[] signature = signedCms.Encode();
return signature;
}
