Question

我有一个应用程序扫描某些目录中任何超过一定大小的文件。检测到后，它会发送一条警告电子邮件，说明某些文件已达到一定的大小限制。我的问题是我当前的程序将每个文件发送一封电子邮件。意思是如果有10个文件超出限制，那么它将发送10封电子邮件。如何使其编译所有文件并在一封电子邮件中发送这些文件的列表？如果需要，这是我的代码：

private void Form1_Load(object sender, EventArgs e)
    {
        count = 0;
        timer = new Timer();
        timer.Interval = 1000;
        timer.Tick += new EventHandler(timer1_Tick);
        timer.Start();


        List<string> s1 = System.IO.Directory.GetFiles(@"F:\gdimaging\data", "*.*", SearchOption.AllDirectories).ToList<string>();
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\hios\DATA", "*.*", SearchOption.AllDirectories).ToList<string>());
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\imgviewer\data", "*.*", SearchOption.AllDirectories).ToList<string>());
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\newcnas\data", "*.*", SearchOption.AllDirectories).ToList<string>());
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\newpod\data", "*.*", SearchOption.AllDirectories).ToList<string>());
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\OMS\data", "*.*", SearchOption.AllDirectories).ToList<string>());
        s1.AddRange(System.IO.Directory.GetFiles(@"F:\WEBIMG", "*.*", SearchOption.AllDirectories).ToList<string>());


        dt.Columns.Add("File_Name");
        dt.Columns.Add("File_Type");
        dt.Columns.Add("File_Size");
        dt.Columns.Add("Create_Date");
        ArrayList fileList = new ArrayList();      
        foreach(string s in s1)
        {   
            try
            {   
                FileInfo info = new FileInfo(s);
                FileSystemInfo sysInfo = new FileInfo(s);
                dr = dt.NewRow();
                //System.Collections.Generic.List<string> nameList;
                dr["File_Name"] = sysInfo.Name;
                dr["File_Type"] = sysInfo.Extension;
                dr["File_Size"] = (info.Length / 1024).ToString();
                dr["Create_Date"] = sysInfo.CreationTime.Date.ToString("dd/MM/yyyy");
                dt.Rows.Add(dr);


                if ((info.Length / 1024) > 1500000)
                {
                    fileList.Add(sysInfo.Name);
                }

                if (dt.Rows.Count > 0)
                {
                    dataGridView1.DataSource = dt;
                }
            }
            catch (UnauthorizedAccessException ex)
            {
                MessageBox.Show("Error : " + ex.Message);
                continue;
            }

        }

        MessageBox.Show(fileList + "overlimit!!");

}

在foreach循环中检查文件大小后，将超过特定限制的这些文件添加到另一个数组，并将数组元素连接到位于for循环之外的消息体中。

在一个类中封装Mail选项使用公共方法/属性，如果其中一个文件符合条件，则返回布尔值，并且仅在满足条件时执行邮件操作：

类似的东西 - 没有像在文本编辑器中的Mac上那样进行检查
