C#发送邮件附件问题
我用是的VS自带的using System.Net.Mail;的命名空间去发送邮件，发送一般的邮件还可以 附件在100KB左右都运行的正常 但是附件一但过大 例如1M 消耗的时间就会达到1min 以上 有没有高手帮我解决下这个速度的问题？ --------------------编程问答-------------------- 没有做邮件的高手么？ --------------------编程问答-------------------- 这个很正常...附件越大..发送速度会越慢..你用Jmail试试 看看速度怎么样. --------------------编程问答-------------------- 你不会还在用猫拨号吧 --------------------编程问答--------------------
能不能不用第三方控件去做咧！~
第三方控件快 它是怎么写的咧？ 能否给我个思路啊？
谢谢！~ --------------------编程问答--------------------
这跟用猫拨号有联系不？ --------------------编程问答--------------------
猫上网慢，这地球人都知道的。 --------------------编程问答--------------------
就算不是用猫 当附件超过2M 时 发送就会超时？
这个怎么解决？ --------------------编程问答--------------------
