Property Value
Type:
System..::.StringA String that contains the name or IP address of the computer to use for SMTP transactions.
The value of the Host property can also be set using constructors or the application or machine configuration file. For more information, see <mailSettings> Element (Network Settings).
If information is specified using this property, this information overrides the configuration file settings.
The following code example demonstrates sending an e-mail message by using the host and port specified in an application configuration file.
public static void CreateTestMessage4(string server)
{
MailAddress from = new MailAddress("ben@contoso.com");
MailAddress to = new MailAddress("Jane@contoso.com");
MailMessage message = new MailMessage(from, to);
message.Subject = "Using the SmtpClient class.";
message.Body = @"Using this feature, you can send an e-mail message from an application very easily.";
SmtpClient client = new SmtpClient(server);
Console.WriteLine("Sending an e-mail message to {0} by using SMTP host {1} port {2}.",
to.ToString(), client.Host, client.Port);
try {
client.Send(message);
}
catch (Exception ex) {
Console.WriteLine("Exception caught in CreateTestMessage4(): {0}",
ex.ToString() );
}
}
static void CreateTestMessage4( String^ server )
{
MailAddress^ from = gcnew MailAddress( L"ben@contoso.com" );
MailAddress^ to = gcnew MailAddress( L"Jane@contoso.com" );
MailMessage^ message = gcnew MailMessage( from,to );
message->Subject = L"Using the SmtpClient class.";
message->Body = L"Using this feature, you can send an e-mail message from an application very easily.";
SmtpClient^ client = gcnew SmtpClient( server );
Console::WriteLine( L"Sending an e-mail message to {0} by using SMTP host {1} port {2}.", to, client->Host, client->Port );
client->Send( message );
client->~SmtpClient();
