sending otp in email after submit form

i am done email sending after submit the form.but i can`t send otp to email.

[AllowAnonymous]
[Route("Register")]
public async Task Register(RegisterBindingModel model)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
var user = new ApplicationUser() { UserName = model.Email, Email = model.Email };
IdentityResult result = await UserManager.CreateAsync(user, model.Password);
if (!result.Succeeded)
{
return GetErrorResult(result);
}
MailMessage mm = new MailMessage("fromemail", "toemail");
mm.Subject ="Leave Reject";
mm.Body = "Hi Sir, " ;
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("email", "password");
smtp.EnableSsl = true;
smtp.Send(mm);
return Ok();
}

follow this

//EmailOtp verification and save otp to database.
public JsonResult SendEmail(string email)
{
string message = "This email address does not match our records.";
EmailOtp user = db.EmailOtps.Where(x => x.Email == email).FirstOrDefault();
if (user != null)
{
string username = user.UserName;
string password = user.Password;
// to send the random password in email
string strNewPassword = GeneratePassword().ToString();
user.OTP = strNewPassword;
db.SaveChanges();
if (!string.IsNullOrEmpty(password))
{
MailMessage mm = new MailMessage("[email protected]", email);
mm.Subject = "Password Recovery";
mm.Body = string.Format("Hi {0},Your password is {1}{2}.Thank You.", username, password, strNewPassword);
mm.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential NetworkCred = new NetworkCredential();
NetworkCred.UserName = "[email protected]";
NetworkCred.Password = "password";
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
message = "Password has been sent to your email address.";
}
}
return Json(message, JsonRequestBehavior.AllowGet);
}
//For generating random number
public string GeneratePassword()
{
string PasswordLength = "6";
string NewPassword = "";
string allowedChars = "";
allowedChars = "1,2,3,4,5,6,7,8,9,0";
//allowedChars += "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,";
//allowedChars += "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,";
char[] sep = {','};
string[] arr = allowedChars.Split(sep);
string IDString = "";
string temp = "";
Random rand = new Random();
for (int i = 0; i < Convert.ToInt32(PasswordLength); i++)
{
temp = arr[rand.Next(0, arr.Length)];
IDString += temp;
NewPassword = IDString;
}
return NewPassword;
}

Note:- password means OTP for reset password (in other words a temporary password)
