问题描述
发送电子邮件时我收到错误

SqlCommand cmd = new SqlCommand（）;
SqlDataReader dr;
try
{
SqlConnection con = new SqlConnection（ConfigurationManager。 ConnectionStrings [ MatriModel]。ConnectionString）;
if （con.State == ConnectionState.Closed）
{
con.Open（）;
}
// 获取与提供的用户名或电子邮件ID匹配的记录。
cmd = new SqlCommand（ 从tblProfile中选择FullName，其中Email COLLATE Latin1_general_CS_AS = @ emailId，con）;
cmd.Parameters.AddWithValue（ @ emailId，Convert.ToString （txtEmail.Text.Trim（）））;
dr = cmd.ExecuteReader（）;
cmd.Dispose（）;
if （dr.HasRows）
{
string username = string .Empty;
dr.Read（）;
username = dr [ FullName]。ToString（）;
// 生成唯一代码
uniqueCode = Convert.ToString（System.Guid .NewGuid（））;
// 在数据库表的UniquCode字段中更新唯一的随机代码
cmd = new SqlCommand（ update tblProfile set UniqueCode = @uniqueCode，其中Email = @ emailid，con）;
cmd.Parameters.AddWithValue（ @ uniqueCode，uniqueCode）;
cmd.Parameters.AddWithValue（ @ emailid，txtEmail.Text.Trim（） ）;
StreamReader reader = new StreamReader（Server.MapPath（ 〜/ ForgotPasswordTemp.html））;
string readFile = reader.ReadToEnd（）;
string myString = ;
myString = readFile;
myString = myString.Replace（ $$ User $$，username）;
myString = myString.Replace（ $$ EmailId $$，txtEmail.Text） ;
myString = myString.Replace（ $$ Url $$， http：// localhost：18601 / ResetPassword.aspx？emailId = + txtEmail.Text + & uCode = + uniqueCode + ）;
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage（ abc@syssigma.com，dr [ 电子邮件]。ToString（）， 您要求的更改密码。，myString.ToString（））;
System.Net.NetworkCredential mailAuthenticaion = new System.Net.NetworkCredential（ abc@syssigma.com， < span class =code-string> MyPassword）;
System.Net.Mail.SmtpClient mailclient = new System.Net.Mail.SmtpClient（ relay-hosting.secureserver.net， 25 ）;
mailclient.EnableSsl = false ;
mailclient.UseDefaultCredentials = false ;
mailclient.Credentials = mailAuthenticaion;
mail.IsBodyHtml = true ;
mailclient.Send（mail）;
dr.Close（）;
dr.Dispose（）;
cmd.ExecuteReader（）;
cmd.Dispose（）;
con.Close（）;
lblMessage.ForeColor = Color.Green;
lblMessage.Font.Bold = true ;
lblMessage.Text = 密码已发送到您的电子邮件地址。;
txtEmail.Text = ;
