winform截取屏幕并发送邮件

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;
        }
    }
}
