获取本机CPU，硬盘等使用情况
早上的时候接到主管的一个任务，要获取服务器上的cpu,硬盘, 数据库等 的使用情况，并以邮件的方式发给boss， = =没办法，公司的服务器真是不敢恭维，顺便吐槽一下公司的网速，卡的时候30k左右徘徊，这不是在浪费我们的时间吗！！！
话不多说上代码，因为是实习，主管还是挺关照我的，一早就给我发了个类库（里面涉及到要查询本机信息的都有）.这样我剩下了一大半的时间，
这个功能总的来说就两步： 一，先获取本机的信息 二，发送邮件。
获取本机信息用到的类库 SystemInfo.cs 和 DiskInfo.cs
SystemInfo.cs

因为只是查询cpu，和硬盘使用情况 只涉及到这两个类
是在控制台应用程序写的

有点乱，没去弄别的。
主函数中还涉及到了 数据库的信息，刚开始不懂，百度了好久也什么都不太懂，后来就找组织了，经组织训示 终于在mysql (公司用的)中找到了information_schema 这里面记录了整个数据库的信息，在里面找到了两个表 tables 和GLOBAL_STATUS 其他的也没多去看(最主要是不懂英语.)。可以用就行(不过感觉有点不靠谱，网上貌似有说)。
取到数据了之后就是 发邮件了
send.cs
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace sendmail { class send { public void setmail(string content) { System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(); client.Host = "smtp.163.com";//使用163的SMTP服务器发送邮件 client.UseDefaultCredentials = true; client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; client.Credentials = new System.Net.NetworkCredential("这是用户名", "密码"); System.Net.Mail.MailMessage Message = new System.Net.Mail.MailMessage(); Message.From = new System.Net.Mail.MailAddress("发件人的邮箱地址"); Message.To.Add("*********@***.com");//将邮件发送给QQ邮箱 Message.Subject = "电脑监测"; Message.Body = content; Message.SubjectEncoding = System.Text.Encoding.UTF8; Message.BodyEncoding = System.Text.Encoding.UTF8; Message.Priority = System.Net.Mail.MailPriority.High; Message.IsBodyHtml = true; client.Send(Message); } } }
发邮件 在主函数中设置了表格。
到这里基本已经搞定了 其中有链接数据库的因为用到了Help类，也不难，就没贴出来了，自己加上去就行了。
好的功能已经完成了。。。。谢谢！
