方法2:
这个是对于
EMAIL发送系统(C#+基于SMTP认证) 1.0
的改版这个第一版是2002年11月写的，过了一年半了，才有人提意见，就修正了一下，因为后来做的项目一直用不上，也就没有注意到
前段时间有网友反馈了一些问题，这次主要做了一些修正
1,text模式下发往163的邮件内容不见了
2,如果用outlook接收而不是在网上看邮件的话,会发现正文内容,但其后跟着一些乱码.
3,一些新开通的邮箱收到的是乱码，如*@126.com
4,修正了带附件的邮件，打开附件时内容混乱的问题
感谢 Lion互动网络论坛 的smhy8187和邮箱是[email protected]的朋友提供意见
欢迎大家提出修改建议，[注：]最好能把修改稿Mail给我一份，我们共同学习

//1.如果所有的属性都已经设置完毕，可直接使用无参数Send()

发送附近 碰到权限问题

我的系统一旦遇到要访问文件的时候就会出错，其中一个具体信息如下：

"
解决方案：
应该是对目录的访问没有权限。
首先修改文件夹属性：
资源管理器 -> 工具 -> 文件夹选项 -> 显示 -> 把简单文件共享的选择去掉（默认是打钩的）
选择上传文件夹 -> 右键 -> 安全 -> 把everyone用户的读写权限都加上。
