Hi I have written the following code (using snippets) and need to pick up any file that has the .txt file extension in a specific folder. I have tried many code snippets and just cant get it right.

Please can someone modify or help me:confused:

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Windows;
using System.Web.Mail;

namespace TfL
{
    class Program
    {
        static void Main(String[] args)
        {
            System.IO.FileInfo info = new System.IO.FileInfo("c:\\Source\\LNS_IS.txt");

            if (File.Exists("c:\\Source\\LNS_IS.txt") && (info.Length > 0))
            {
                MailMessage oMsg = new MailMessage();
                oMsg.From = "[e-mail]";
                oMsg.To = "[e-mail]";
                oMsg.Subject = "Unattended Mailbox do not reply";
                oMsg.BodyFormat = MailFormat.Html;

                // ADD AN ATTACHMENT.
                String sFile = @"C:\Source\LNS_IS.TXT";
                MailAttachment oAttch = new MailAttachment(sFile, MailEncoding.Base64);

                oMsg.Attachments.Add(oAttch);

                //SMTP server.
                SmtpMail.SmtpServer = "vmtestmac";
                SmtpMail.Send(oMsg);

                oMsg = null;
                oAttch = null;


                //move the file now email is sent
                string sourceFile = @"C:\Source\LNS_IS.txt";
                string destinationFile = @"C:\Archive\LNS_IS.txt";
                System.IO.File.Move(sourceFile, destinationFile);

                //shows message for testing
                global::System.Windows.Forms.MessageBox.Show("sending File Exists ");

            }
            else
            {
                MailMessage oMsg = new MailMessage();
                oMsg.From = "[e-mail]";
                oMsg.To = "[e-mail]";
                oMsg.Subject = "Unattended Mailbox do not reply";
                oMsg.BodyFormat = MailFormat.Html;

                //SMTP server.
                SmtpMail.SmtpServer = "vmtestmac";
                SmtpMail.Send(oMsg);

                oMsg = null;

                //shows message for testing
                global::System.Windows.Forms.MessageBox.Show("sending file not exist");
            }

            //checking if file has any data


            if (info.Length < 1)
            {
                //move the file 
                string sourceFile = @"C:\Source\LNS_IS.txt";
                string destinationFile = @"C:\Baddata\LNS_IS.txt";
                System.IO.File.Move(sourceFile, destinationFile);

             }


        }

    }
}

推荐答案

尝试一下:

Try this:

DirectoryInfo dirInfo = new DirectoryInfo(@"c:\MyDir");
string[] files = dirInfo.GetFiles("*.txt", SearchOption.TopDirectoryOnly);

感谢约翰，然后我使用这段代码得到了两个错误:-

' System.IO.DirectoryInfo.GetFiles(string，System.IO.SearchOption)'的最佳重载方法匹配有一些无效的参数

和

参数"2":无法从布尔"转换为"System.IO.SearchOption"

任何想法:困惑:

Thanks John then I use this code i get two errors:-

best overloaded method match for 'System.IO.DirectoryInfo.GetFiles(string, System.IO.SearchOption)' has some invalid arguments

and

Argument ''2'': cannot convert from ''bool'' to ''System.IO.SearchOption''

Any Ideas:confused:

再次感谢约翰，但我仍然遇到错误:-

无法隐式转换类型' System.IO.FileInfo []'.到' string []'
:(

Thanks Again John but I still got an error:-

Cannot implicitly convert type 'System.IO.FileInfo[]' to 'string[]'
:(
