A generic base64 file encoding code should resolve:

using (var fs = new FileStream("C:\Caminho\Do\Arquivo.pdf", FileMode.Open, FileAccess.Read)) 
{
    byte[] bytesArquivo = new byte[fs.Length];
    fs.Read(bytesArquivo, 0, Convert.ToInt32(fs.Length));
    string stringEmBase64 = Convert.ToBase64String(bytesArquivo); 
}

To make XML, use Mark Rasmussen's XmlOutput class . I made a NuGet package for her . The usage is like this:

var xo = new XmlOutput()
    .XmlDeclaration()
    .Node("conteudoArquivoP7S").InnerText(stringEmBase64);
