Question

如何使用C＃從我的郵件（例如gmail）下載電子郵件附件？

Answer 1

以下代碼取自Extract Attachments sample，它附帶我們的Rebex Mail組件。 HOWTO: Download emails from a GMail account in C#博文中包含從POP3服務器下載的內容。

// Load mail message from disk 
MailMessage mail = new MailMessage(); 
mail.Load (args[0]); 

Console.WriteLine (
    "Message contains {0} attachments.", 
    mail.Attachments.Count 
); 

// If message has no attachments, just exit 
if (mail.Attachments.Count == 0) 
    return 0; 

foreach (Attachment attachment in mail.Attachments) 
{ 
    // Save the file 
    Console.WriteLine ("Saving '{0}' ({1}).", 
    attachment.FileName, attachment.MediaType); 
    attachment.Save (attachment.FileName); 
} 

Answer 2

// Firstly you might want to use POP3Class which is mail support class. 

    POP3Class Pop3= new POP3Class(); 
    pop3.DoConnect("your.mail.server",110,"username","password"); 
    pop3.GetStat(); 


    // and then you can use the below code for storing an attachment. 

    MailMessage mail = new MailMessage(); 
    Mail.Load (args[0]); 

    Console.WriteLine (
    "Message contains {0} attachments.", 
    mail.Attachments.Count 
    ); 

    // If message has no attachments, just exit 
    if (mail.Attachments.Count == 0) 
    return 0; 

    foreach (Attachment attachment in mail.Attachments) 
    { 
    // Save the file 
    Console.WriteLine ("Saving '{0}' ({1}).", 
    attachment.FileName, attachment.MediaType); 
    attachment.Save (attachment.FileName); 
    } 


// Hope that helps.
