SmtpClient Constructor (String^)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Initializes a new instance of the SmtpClient class that sends e-mail by using the specified SMTP server.

Namespace:   System.Net.Mail
Assembly:  System (in System.dll)

	String^ host


Type: System::String^

A String that contains the name or IP address of the host computer used for SMTP transactions.

The host parameter is used to initialize the value of the Host property. The Credentials and Port properties are initialized by using the settings in the application or machine configuration files. If host is null or equal to String::Empty, Host is initialized using the settings in the application or machine configuration files.

For more information about using the application and machine configuration files, see <mailSettings> Element (Network Settings). If information is specified using SmtpClient constructors or properties, this information overrides the configuration file settings.

The following code example demonstrates calling this constructor.

static void CreateTimeoutTestMessage( String^ server )
   String^ to = L"";
   String^ from = L"";
   String^ subject = L"Using the new SMTP client.";
   String^ body = L"Using this new feature, you can send an e-mail message from an application very easily.";
   MailMessage^ message = gcnew MailMessage( from,to,subject,body );
   SmtpClient^ client = gcnew SmtpClient( server );
   Console::WriteLine( L"Changing time out from {0} to 100.", client->Timeout );
   client->Timeout = 100;

   // Credentials are necessary if the server requires the client 
   // to authenticate before it will send e-mail on the client's behalf.
   client->Credentials = CredentialCache::DefaultNetworkCredentials;
   client->Send( message );


to construct an SmtpClient. Associated enumeration: SmtpAccess::Connect.
