Sending email in ASP.NET

Many times I tried to send an email through .net. Although there are many posts still contains to send an email through .net. But in this article I have created a class which have differenet methods like getSMTPInfo() and MailConfiguration(string to, string from, string cc, string bcc) and SendMail(string subject, string emailBody)

Let me explains you what these methods does.

/// <summary>

/// This Method gets the all SMTP Information

/// </summary>

GetSMTPInfo()
{
System.Collections.Hashtable section;
System.Collections.IDictionaryEnumerator enumerator;
try
{
section = (System.Collections.Hashtable)

ConfigurationManager.GetSection("ReportsEmail/SMTP");

enumerator = section.GetEnumerator();

while (enumerator.MoveNext())

{
if (enumerator.Entry.Key.ToString() == "Host")

{
SMTPHost = enumerator.Entry.Value.ToString();
}
else if (enumerator.Entry.Key.ToString() == "Port")
{
if (enumerator.Entry.Value.ToString() != "")
{
int.TryParse(enumerator.Entry.Value.ToString(), out port);
}
}
else if (enumerator.Entry.Key.ToString() == "UserName")
{
smtpuser = enumerator.Entry.Value.ToString();
}
else if (enumerator.Entry.Key.ToString() == "Password")
{
smtppass = enumerator.Entry.Value.ToString();
}
else if (enumerator.Entry.Key.ToString() == "EnableSSL") {
int value = 0;
int.TryParse(enumerator.Entry.Value.ToString(), out value);
if (value == 1)
enablessl = true;
 else
enablessl = false;
}
}
if (message.To.Count < 1)
{
return;
}

message.From = new MailAddress(this.from);
if (this.cc != "")
{
string[] multipleMailArraycc = this.cc.Split(',');
if (multipleMailArraycc != null && multipleMailArraycc.Length > 0)
{
for (int z = 0; z < multipleMailArraycc.Length; z++)
{
if (multipleMailArraycc[z].Trim() != "")Z
{
message.CC.Add(multipleMailArraycc[z].Trim());

}
}
}

if (this.bcc != "")
{
string[] multiplebcc = this.bcc.Split(',');
if (multiplebcc != null && multiplebcc.Length > 0)
{
for (int z = 0; z < multiplebcc.Length; z++)
{
if (multiplebcc[z].Trim() != "")
{
message.Bcc.Add(multiplebcc[z].Trim());
}
}
}
}

//message.To.Add(this.to);

//message.From = new MailAddress(this.from);

//if (this.cc != "") message.CC.Add(this.cc);

//if (this.bcc != "") message.Bcc.Add(this.bcc);

message.Subject = subject;
message.IsBodyHtml = true;
message.Body = emailBody;
SmtpClient mailClient = new SmtpClient(this.SMTPHost);
if (this.port > 0)
{
mailClient.Port = this.port;
}
if (this.isDefaultCredential == false)
{
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = basicAuthenticationInfo;
}
 else
{
mailClient.UseDefaultCredentials = true;

}
}
catch (Exception ex)
{
throw ex;
}
}

/// <summary>

/// This method gets the Configuration Details of the Mail

/// </summary>

/// <param name="to">to addresses separated by semicolon</param>

/// <param name="from">from address</param>

/// <param name="cc">cc addresses separated by semicolon</param>

/// <param name="bcc">bcc addresses separated by semicolon</param>

MailConfiguration(string to, string from, string cc, string bcc):

{

this.to = to;
this.from = from;
this.cc = cc;
this.bcc = bcc;
getSMTPInfo();
if (smtpuser != "" && smtppass != "")
{
this.basicAuthenticationInfo = new NetworkCredential(smtpuser, smtppass);
this.isDefaultCredential = false;
}
 else
{
this.isDefaultCredential = true;
}
}

/// <summary>

/// This Method send a mail to the specified Receipient list

/// </summary>

/// <param name="bodyDetail"></param>

SendMail(string subject, string emailBody)
{
MailMessage message = new MailMessage();
 try
{
string[] multipleMailArray = this.to.Split(',');
if (multipleMailArray != null && multipleMailArray.Length > 0)
{
for (int z = 0; z < multipleMailArray.Length; z++)
{
if (multipleMailArray[z].Trim() != "")
{

message.To.Add(multipleMailArray[z].Trim());
}
}
}
mailClient.EnableSsl = this.enablessl;
mailClient.Send(message);
}
catch (Exception ex)
{

throw ex;
}
}

In the Web.Config file,We need to add the Section group for SMTP Configurations inside Configsections tag.

<sectionGroup name="ReportsEmail">
<section name ="SMTP" type ="System.Configuration.SingleTagSectionHandler"/>
</sectionGroup>

Again As we have given the name of the section name as ReportsEmail

In the ReportEmail section tags We need to add the SMTP configurations

<ReportsEmail>
<SMTP Host="smtp.gmail.com" //give the name of the Host name
 UserName="[email protected]" Password="Password"
Port="25"
 EnableSSL="1">
</SMTP>
</ReportsEmail>

and Again if you want to send a mail on a click of the Button,We just need to create an instance of the mail Configuration Class and call that method SendMail with instance.

Thats it!!!
