MailAddress.ToString メソッド


このインスタンスの文字列形式を返します。Returns a string representation of this instance.

 override System::String ^ ToString();
public override string ToString ();
override this.ToString : unit -> string
Public Overrides Function ToString () As String



この String の内容を格納している MailAddressA String that contains the contents of this MailAddress.

次のコード例では、電子メールメッセージの送信先を表示します。The following code example displays the destination of an email message.

static void CreateTestMessage4( String^ server )
   MailAddress^ from = gcnew MailAddress( L"" );
   MailAddress^ to = gcnew MailAddress( L"" );
   MailMessage^ message = gcnew MailMessage( from,to );
   message->Subject = L"Using the SmtpClient class.";
   message->Body = L"Using this feature, you can send an email message from an application very easily.";
   SmtpClient^ client = gcnew SmtpClient( server );
   Console::WriteLine( L"Sending an email message to {0} by using SMTP host {1} port {2}.", to, client->Host, client->Port );
   client->Send( message );

public static void CreateTestMessage4(string server)
    MailAddress from = new MailAddress("");
    MailAddress to = new MailAddress("");
    MailMessage message = new MailMessage(from, to);
    message.Subject = "Using the SmtpClient class.";
    message.Body = @"Using this feature, you can send an email message from an application very easily.";
    SmtpClient client = new SmtpClient(server);
    Console.WriteLine("Sending an email message to {0} by using SMTP host {1} port {2}.",
         to.ToString(), client.Host, client.Port);

    catch (Exception ex)
        Console.WriteLine("Exception caught in CreateTestMessage4(): {0}",


このメソッドによって返される文字列は、インスタンスの作成時に指定された文字列と必ずしも同じであるとは限りません。The string returned by this method is not necessarily identical to the string specified when the instance was created. DisplayNameプロパティがではなく null String.Empty ("") の場合は、 ToString 次の構文を使用して構成された文字列を返します。If the DisplayName property is not null and not equal to String.Empty (""), ToString returns a string composed using the following syntax:

DisplayName <User@Host>DisplayName <User@Host>

DisplayNamenull またはに等しい場合は String.EmptyToString プロパティの値を返し Address ます。If DisplayName is null or is equal to String.Empty, ToString returns the value of the Address property.
