Hi Friends,
In this article I will tell you how to send email using WCF
Service. We can send email directly from the client; however, in some cases you
can't send external emails directly. In that case we need WCF service for
sending email from client.
In this article, I will first explain how to create WCF
service then I will try to implement email functionality using WCF Service. In
this article I am using Gmail to send email., that why user must have gmail
account for sending email.
1.
Create WCF Service Class Library
Create a new Project WCF Class Library Project and Name it
EmailServices.
Step
1: Create service contract as IEmailService and add OperationContract
SendEmail
for sending email. This method uses gmailuseraddress ,password and email
to and cc subject as parameter
[ServiceContract]
public interface IEmailService
{
[OperationContract]
string SendEmail(string
gmailUserAddress, string gmailUserPassword, string[] emailTo,string[]
ccTo, string subject, string
body, bool isBodyHtml);
}
Step
2: Add EmailService class and Implement IEmailService.
public class EmailService : IEmailService
{
private static string SMTPSERVER = "smtp.gmail.com";
private static int PORTNO = 587;
public string
SendEmail(string gmailUserName, string gmailUserPassword, string[]
emailToAddress, string[] ccemailTo, string subject, string
body, bool isBodyHtml)
{
if (gmailUserName == null
|| gmailUserName.Trim().Length == 0)
{
return "User
Name Empty";
}
if (gmailUserPassword == null
|| gmailUserPassword.Trim().Length == 0)
{
return "Email
Password Empty";
}
if (emailToAddress == null
|| emailToAddress.Length == 0)
{
return "Email
To Address Empty";
}
List<string>
tempFiles = new List<string>();
SmtpClient smtpClient = new
SmtpClient(SMTPSERVER, PORTNO);
smtpClient.EnableSsl = true;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new NetworkCredential(gmailUserName,
gmailUserPassword);
using (MailMessage
message = new MailMessage())
{
message.From = new MailAddress(gmailUserName);
message.Subject = subject == null ? "" : subject;
message.Body = body == null ? "" : body;
message.IsBodyHtml = isBodyHtml;
foreach (string
email in emailToAddress)
{
message.To.Add(email);
}
if (ccemailTo != null && ccemailTo.Length > 0)
{
foreach (string
emailCc in ccemailTo)
{
message.CC.Add(emailCc);
}
}
try
{
smtpClient.Send(message);
return "Email
Send SuccessFully";
}
catch
{
return "Email
Send failed";
}
}
}
}
Step 3: Build your Class library.
2.
Add WCF Service Application Project
Step 1: Add reference of Classlibrary Project to that WCFServiceHost project.
Step 2: Delete IService1.Cs and codebehind file
Step3 : Right
click on that SaleService.svc and select view
Markup:
Step 4: Change the Service
Name from that markup:
<%@ ServiceHost
Language="C#"
Debug="true"
Service="EmailServices.EmailService"
CodeBehind="EmailService.svc.cs"
%>
Step 5: And
build the solution and
WCFServiceHost
set as startup project and EmailService.svc set
as startup page and run the service
