asp.net send email with excel attachement - asp.net-core

Question

I want to create excel file and send it as attachment via email
hear is my code for creating excel file but i can't send it by email , the email sent but without attachment.
this for creating excel file.
DataTable dt = new DataTable("Grid");
dt.Columns.AddRange(new DataColumn[4] { new DataColumn("H_Id"),
new DataColumn("H_Name"),
new DataColumn("H_PassNo"),
new DataColumn("H_Pass_Issue"),
});
var marydatas = from MarryData in this._context.MarryData.Take(10)
select MarryData;
foreach (var marryData in marydatas)
{
dt.Rows.Add(marryData.H_Id, marryData.H_Name, marryData.H_PassNo, marryData.H_Pass_Issue);}
byte[] bytes = null;
using (XLWorkbook wb = new XLWorkbook())
{
wb.Worksheets.Add(dt);
using (MemoryStream stream = new MemoryStream())
{
wb.SaveAs(stream);
bytes = stream.ToArray();
}
}
and this for sending email
var message = new MimeMessage();
message.From.Add(new MailboxAddress("test project", "maazonuae#gmail.com"));
message.To.Add(new MailboxAddress("naren", "a.saaeed81#gmail.com"));
message.Subject = "test maazon";
message.Body = new TextPart("HTML Table Exported Excel Attachment")
{
Text = "hello"
};
var builder = new BodyBuilder();
builder.Attachments.Add("Customers.xlsx", new MemoryStream(bytes));
var body = builder.ToMessageBody();
var emailBody = new MimeKit.BodyBuilder
{
};
emailBody.Attachments.Add("Customers.xlsx", bytes);
using (var client = new SmtpClient())
{
client.Connect("smtp.gmail.com", 587, false);
client.Authenticate("maazonuae#gmail.com", "maazonuae2021");
client.Send(message);
client.Disconnect(true);
}
so when it run just send email without attachment and send (Text = "hello") in attached file not in body message.
thanks

i found solution
var message = new MimeMessage();
message.From.Add(new MailboxAddress(Joey", "joey#friends.com));
message.To.Add(new MailboxAddress("Alice", "alice#wonderland.com"));
message.Subject = "How you doin?";
var builder = new BodyBuilder();
// Set the plain-text version of the message text
builder.TextBody = #"Hey Alice,
What are you up to this weekend? Monica is throwing one of her parties on
Saturday. I was hoping you could make it.
Will you be my +1?
-- Joey
";
builder.Attachments.Add("myFile.xlsx", bytes);
// Now we just need to set the message body and we're done
message.Body = builder.ToMessageBody();
