The code sample below defines signer information and signs the file:

C#

using DevExpress.Office.DigitalSignatures;
using DevExpress.Office.Tsp;
using System;
using System.Diagnostics;
using System.Security.Cryptography.X509Certificates;

static void SignDocument(string path, string output)
{
    DocumentSigner documentSigner = new DocumentSigner();
    documentSigner.Sign(path, output, CreateSignatureOptions(),
     CreateSignatureInfo());
    Process.Start(output);
}

static SignatureInfo CreateSignatureInfo()
{
    SignatureInfo signatureInfo = new SignatureInfo();
    signatureInfo.CommitmentType = CommitmentType.ProofOfApproval;
    signatureInfo.Time = DateTime.UtcNow;
    signatureInfo.ClaimedRoles.Clear();
    signatureInfo.ClaimedRoles.Add("Sales Representative");
    signatureInfo.Country = "USA";
    signatureInfo.City = "Seattle";
    signatureInfo.StateOrProvince = "WA";
    signatureInfo.Address1 = "507 - 20th Ave. E.";
    signatureInfo.Address2 = "Apt. 2A";
    signatureInfo.PostalCode = "98122";
    signatureInfo.Comments = "Demo Digital Signature";
    return signatureInfo;
}
static SignatureOptions CreateSignatureOptions()
{
    X509Certificate2 certificate =
     new X509Certificate2("Certificate/SignDemo.pfx", "dxdemo");
    Uri tsaServer = new Uri("https://freetsa.org/tsr");

    SignatureOptions options = new SignatureOptions();
    options.Certificate = certificate;
    options.DigestMethod = HashAlgorithmType.SHA256;

    return options;
}
