SmtpClientAsyncResult Class

Provides an implementation of System.IAsyncResult for use by BeginSendMail method and BeginTestRecipients method to implement the standard asynchronous method pattern.

System.Object
    EASendMail.SmtpClientAsyncResult

[Visual Basic]
Public Class SmtpClientAsyncResult
    Implements IAsyncResult

[C#]
public class SmtpClientAsyncResult : IAsyncResult
