SmtpClient::Timeout Property
Gets or sets a value that specifies the amount of time after which a synchronous Send call times out.
Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | The value specified for a set operation was less than zero. |
| InvalidOperationException | You cannot change the value of this property when an email is being sent. |
By default, calls to the Send method block until the operation completes. If you set the Timeout property to a positive value, and a Send operation cannot complete in the allotted time, the SmtpClient class throws an SmtpException exception.
To send a message and continue executing in the application thread, use the SendAsync method.
The following code example demonstrates getting and setting the time-out value.
static void CreateTimeoutTestMessage( String^ server ) { String^ to = L"jane@contoso.com"; String^ from = L"ben@contoso.com"; 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 ); }
