Upload Files to Remote PC

Here first You have to create a folder in remote machine and You have to share that folder with other network users.

And then using following method you can upload files to the remote shared folder. public int FileUpload(string SourceFilepath)
{
try
{
WebClient client = new WebClient();

//Credential information for remote Mechine.-> here I used Username=erandika1986 and Password=123
NetworkCredential nc = new NetworkCredential("erandika1986", "123");

//Here we have to give destination information
Uri addy = new Uri(@"\\192.168.2.4\UploadDocs\" + fileName);

//Here we set the the credential information to the Webclient
client.Credentials = nc;

//upload the file from Source to the destination
client.UploadFile(addy, SourceFilepath);

return 1;

}
catch (Exception ex1)
{
MessageBox.Show(ex1.Message);
return 0;
}

Send Email using SMTP Server

The .NET Framework includes the System.Net.Mail namespace, whcich provides classes to create and send email messages.Messages can include plain text,HTML and attachments

Creating & Send an email

Here We will create a class called email and we will implement the method called SendEmail inside the class.

Here the implemented class

***********************************************************
Remember you should add namespace "System.Net.Mail" first
***********************************************************

public class email
{
public int SendEmail()
{
try
{
//Create a MailMessage object
MailMessage mail = new MailMessage();

//To specify sender email address and Sender name
mail.From = new MailAddress("sender Email address", "Sender name");

//To specify recipient email address and recipient name
mail.To.Add(new MailAddress("recipient email address", "recipient name"));

//Set email Subject
mail.Subject = "Sample Email";

//Specify as HTML message body
mail.Body ="This is my message body";

//To Enable HTML body->You can type your message body using html tag.But blogger not support to post html tag in here.To enable HTML body you can use following code line.
//mail.IsBodyHtml = true;

//Attach files
mail.Attachments.Add(new Attachment(@"D:\oracle_database_11g.pdf"));


//Create a SmtpClient object
SmtpClient client = new SmtpClient();

//Assign a host for the client
client.Host = "smtp.gmail.com";

//Assign a port
client.Port=587;

//Give Credential information->Username and Password
client.Credentials=new System.Net.NetworkCredential("Your Username","Your Password");

//To enable SSL
client.EnableSsl=true;

//Send the mail
client.Send(mail);

return 1;
}
catch (Exception ex1)
{
MessageBox.Show(ex1.Message);
return 0;
}
}

How to use MS Outlook API to send mails

First You have to add Microsoft.Office.Interop.Outlook using References.To do that go to Solution Explorer->Reference->Add Reference->.NET tab->Microsoft.Office.Interop.Outlook.

After that we will create a small class called SendEmails and we will implement a method called sendGroupmail.

Here the Implementation for SendEmails Class.

public class SendEmails
{
public int sendGroupMail(string recipientsList, string subject, string body)
{
Outlook.Application objectOutLook = new Outlook.Application();

try
{
Outlook.MailItem mailItem = objectOutLook.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;
mailItem.Subject = subject;
mailItem.To = recipientsList;
mailItem.Body = body;
Outlook.NameSpace ns = objectOutLook.GetNamespace("mapi");
ns.Logon(Missing.Value, Missing.Value, true, true);
mailItem.Importance = Outlook.OlImportance.olImportanceLow;
((Outlook.MailItem)mailItem).Send();
ns.Logoff();
return 1;
}
catch (Exception ex2)
{
MessageBox.Show(ex2.Message);
return 0;
}

}
}

How to use this class.........

SendEmails newemail=new SendEmails();
int result = newemail.sendGroupMail("example@mail.com", "This is Subject", "This is Body");
