Answer 5

大家给点意见，这样写好不好啊昨天网站的代码突然发送失败了，就临时写成现在这样的，用web发送的就可以了，微软还说过时
net里面发送的却不行，不知道代码有没有写错，不过以前是可以用的

Answer 6

顶，为啥还分web和net的呢？有啥不一样的用途？

Answer 7

.net分2种形式发送邮件啊
一个是System.Web.Mail一个是System.Net.Mail

Answer 8

System.Web.Mai好像是在1.1时候使用
System.Net.Mail是2.0下的,推荐使用System.Net.Mail

Answer 9

System.Net.Mail是2.0下的,推荐使用System.Net.Mail就是用这个错的啊
我现在改1.0就没错了
