做了一个winform程序，可以手动截取整个屏幕，也可以自动定时截取屏幕，并发送到指定的邮箱。
窗体界面如下：
截取屏幕和发送邮件代码如下：
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
using System.Net.Mail;
using System.Net;
namespace Snapshot
{
public class Common
{
/// <summary>
/// 截图屏幕
/// </summary>
public static void ScreenSnapshot(string filepath)
{
Screen scr = Screen.PrimaryScreen;
Rectangle rc = scr.Bounds;
int iWidth = rc.Width;
int iHeight = rc.Height;
Image myImage = new Bitmap(iWidth, iHeight);
Graphics g = Graphics.FromImage(myImage);
g.CopyFromScreen(new Point(0, 0), new Point(0, 0), new Size(iWidth, iHeight));
myImage.Save(filepath);
}
/// <summary>
/// 发送邮件
/// </summary>
/// <param name="toAddress">收件人</param>
/// <param name="mailSubject">邮件主题</param>
/// <param name="mailBody">邮件内容</param>
/// <param name="mailAttachList">附件路径</param>
/// <returns></returns>
public static bool SendMail(string toAddress, string mailSubject, string mailBody, List<string> mailAttachList)
{
MailAddress from = new MailAddress("xxx@163.com", "J.L.C"); //设置发件人信箱,及显示名字
MailAddress to = new MailAddress(toAddress, "JLC"); //设置收件人信箱,及显示名字
using (MailMessage oMail = new MailMessage(from, to)) //创建一个MailMessage对象
{
oMail.Subject = mailSubject; //邮件标题
oMail.Body = mailBody; //邮件内容
oMail.IsBodyHtml = true; //指定邮件格式,支持HTML格式
oMail.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312");//邮件采用的编码
oMail.Priority = MailPriority.High;//设置邮件的优先级为高
foreach (string attach in mailAttachList)//附件路径
oMail.Attachments.Add(new Attachment(attach));
//发送邮件服务器
SmtpClient client = new SmtpClient();
client.Host = "smtp.163.com"; //指定邮件服务器
client.Credentials = new NetworkCredential("xxx@163.com", "xxx");//指定发件人邮箱,及密码
try
{
client.Send(oMail); //发送邮件
}
catch
{
return false;
}
}
return true;
}
}
}
