我试图让我的web应用程序在每次将数据插入数据库时都会发送电子邮件更新,就像我将在下面显示的代码一样。插入数据时无法发送电子邮件更新
这是一个btnAssign在那里将更新数据
protected void btnAssign_Click1(object sender, EventArgs e)
{
using (var connAdd = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
{
String assign = ddlpid1.SelectedValue;
connAdd.Open();
var sql = "Update MemberReport Set assignto ='" + assign + "', caseprogress = 'ongoing' where memberreportID='" + lbmemberreportid.Text + "'";
using (var cmdAdd = new SqlCommand(sql, connAdd))
{
cmdAdd.ExecuteNonQuery();
}
sql = "Insert into PoliceReport(memberreportid) values('" + lbmemberreportid.Text + "')";
// sql = "Update PoliceAccount Set handle ='" + assign + "' where policeid ='" + ddlpid1.SelectedValue + "' OR '" + ddlpid2.SelectedValue + "'";
using (var cmdAdd = new SqlCommand(sql, connAdd))
{
cmdAdd.ExecuteNonQuery();
}
sql = "Update PoliceAccount Set handle ='" + lbmemberreportid.Text + "' where policeid ='" + ddlpid1.SelectedValue + "'";
// sql = "Update PoliceAccount Set handle ='" + assign + "' where policeid ='" + ddlpid1.SelectedValue + "' OR '" + ddlpid2.SelectedValue + "'";
using (var cmdAdd = new SqlCommand(sql, connAdd))
{
cmdAdd.ExecuteNonQuery();
}
}
插入/数据库部分的更新工作正常相关的数据库表和列。当我通过选择列添加smtp代码发送电子邮件,它没有工作。
SqlCommand cmd = new SqlCommand();
SqlDataReader dr;
//SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
//con.Open();
// get the records matching the supplied username or email id.
cmd = new SqlCommand("select * from PoliceAccount where handle='" + lbmemberreportid.Text + "'", connAdd);
dr = cmd.ExecuteReader();
cmd.Dispose();
if (dr.HasRows)
{
dr.Read();
StringBuilder strBody = new StringBuilder();
//Passing emailid,username and generated unique code via querystring. For testing pass your localhost number and while making online pass your domain name instead of localhost path.
strBody.Append("<a>Please be notified that you've been assigned a case to handle. Please proceed to the scene with immediate effect.</a>");
// sbody.Append("&uCode=" + uniqueCode + "&uName=" + txtUserName.Text + ">Click here to change your password</a>");
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage("[email protected]", dr["email"].ToString(), "Case Pending", strBody.ToString());
//pasing the Gmail credentials to send the email
System.Net.NetworkCredential mailAuthenticaion = new System.Net.NetworkCredential("[email protected]", "Temasekpoly13");
System.Net.Mail.SmtpClient mailclient = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);
mailclient.EnableSsl = true;
mailclient.Credentials = mailAuthenticaion;
mail.IsBodyHtml = true;
mailclient.Send(mail);
dr.Close();
dr.Dispose();
cmd.ExecuteReader();
cmd.Dispose();
//con.Close();
lbmemberreportid.Text = "";
ddllocation.SelectedIndex = 0;
ddlnumber.SelectedIndex = 0;
ddlpid1.SelectedIndex = 0;
tbdetails.Text = "";
tbproperty.Text = "";
tbsuspect.Text = "";
ddlpid1.Visible = false;
LoadGrid();
lblmsg.ForeColor = System.Drawing.Color.Green;
lblmsg.Text = "MemberReportID" + Session["memberreportid"] + "has been successfully assigned";
}
connAdd.Close();
}
更糟糕的是,消息应该出现的标签没有出现。这意味着在插入数据后,代码基本停止运行。我在link这里添加了一个txtFile,如果我上面粘贴的代码很混乱。
我真的不知道为什么我的电子邮件没有运行后,将数据插入到数据库中。
问候。
您是否试过单步执行代码以确定它为什么会停止? –
尝试步进以确切知道哪一行发生错误。 –
嗯,因为这个代码工作时,我尝试使用它为我的忘记密码功能。但当然,我必须根据我的要求做出相应的改变。所以基本上代码的逻辑是好的,但只是添加到另一个页面后,它不起作用 –
