c#비동기적으로 메시지를 보내는 클래스

먼저 메일 정보의 기본 클래스를 다음과 같이 정의해야 한다.

 
  
/// 
 
  
/// Base message class used for emails 
  
/// 
 
  
public class Message 
  
{ 
  
#region Constructor 
  
/// 
 
  
/// Constructor 
  
/// 
 
  
public Message() 
  
{ 
  
} 
  
#endregion 
   
  
#region Properties
/// 

/// Whom the message is to
/// 

public virtual string To { get; set; }
 
  
/// 

/// The subject of the email
/// 

public virtual string Subject { get; set; }
 
  
/// 

/// Whom the message is from
/// 

public virtual string From { get; set; }
 
  
/// 

/// Body of the text
/// 

public virtual string Body { get; set; }
 
  
#endregion
}
 
 

그리고 메일의 발송 클래스를 정의하고 Netmail 방식으로 메일을 발송하며 메일을 발송할 때 사용합니다.net에서 자체적으로 가지고 있는 스레드 탱크는 다중 스레드를 통해 비동기적으로 발송되며 코드는 다음과 같다.

 
  
 ///

/// 
 
  
public class EmailSender : Message
