我在c＃中查询了检查列表框

Question

我已经设置了一个程序，到目前为止可以浏览一个文件的位置，该文​​件在文本文件中拥有数据，其中包含其他文件的位置，然后显示我是否存在，是否丢失或者是否在列表框内是重复的。下一步是让用户选中已检查列表框中的文件，并为其提供移动或复制选项。我已经制作了允许这样做的按钮，但是我希望能够将它们用于列表框中的复选框。（ps）请忽略我在代码中做出的任何评论，他们只是之前在做其他事情的尝试代码。

到目前为止我的代码：

namespace File_existence
{
    public partial class fileForm : Form
    {
        private string _filelistlocation;

        public fileForm()
        {
            InitializeComponent();
        }

        private void checkedListBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        public void fileForm_Load(object sender, System.EventArgs e)
        {
            _filelistlocation = textBox1.Text;
        }

        private void button1_Click(object sender, System.EventArgs e)
        {
            //GetDuplicates();
            checkedListBox1.Items.Clear();
            listBox2.Items.Clear();
            ReadFromList();
        }

        private void GetDuplicates()
        {
            DirectoryInfo directoryToCheck = new DirectoryInfo(@"C:\\temp");

            FileInfo[] files = directoryToCheck.GetFiles("*.*", SearchOption.AllDirectories);
            var duplicates = files.GroupBy(x => x.Name)
                                .Where(group => group.Count() > 1)
                                .Select(group => group.Key);
            if (duplicates.Count() > 0)
            {
                MessageBox.Show("The file exists");
                FileStream s2 = new FileStream(_filelistlocation, FileMode.Open, FileAccess.Read, FileShare.Read);
                // open _filelistlocation
                // foreach line in _filelistlocation
                // concatenate pat hand filename
                //
            }
        }

        public void ReadFromList()
        {
            int lineCounter = 0;
            int badlineCounter = 0;
            using (StreamReader sr = new StreamReader(_filelistlocation))
            {
                String line;
                while ((line = sr.ReadLine()) != null)
                {
                    string[] values = line.Split('\t');
                    if (values.Length == 2)
                    {
                        string fullpath = string.Concat(values[1], "\\", values[0]);
                        if (File.Exists(fullpath))
                            checkedListBox1.Items.Add(fullpath);
                        else
                            listBox2.Items.Add(fullpath);
                        ++lineCounter;
                    }
                    else
                        ++badlineCounter;
                    //Console.WriteLine(line);
                }
            }
        }


         //StreamReader files= new StreamReader(File)();
         private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e)
        {

        }

         private void button2_Click(object sender, System.EventArgs e)
         {
             FolderBrowserDialog folderBrowserDlg = new FolderBrowserDialog();
             folderBrowserDlg.ShowNewFolderButton = true;
             DialogResult dlgResult = folderBrowserDlg.ShowDialog();
             if (dlgResult.Equals(DialogResult.OK))
             {
                 textBox1.Text = folderBrowserDlg.SelectedPath;
                 Environment.SpecialFolder rootFolder = folderBrowserDlg.RootFolder;
             }
             try
             {
                 string fileName = "filetest1.txt";
                 string sourcePath = @"C:\Temp\Trade files\removed";
                 string targetPath = @"C:\Temp\Trade files\queued";
                 string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
                 string destFile = System.IO.Path.Combine(targetPath,fileName);
                 System.IO.File.Copy(sourceFile, destFile, true);
             }

             catch (IOException exc)
             {
                 MessageBox.Show(exc.Message);
             }
         }


         private void button3_Click(object sender, System.EventArgs e)
         {
             try
             {
                 string sourceFile = @"C:\Temp\Trade Files\queued\filetest1.txt";
                 string destinationFile = @"C:\Temp\Trade Files\processed\filetest1.txt";

                 System.IO.File.Move(sourceFile, destinationFile); 
             }
             catch(IOException ex){
                 MessageBox.Show(ex.Message);//"File not found"
             }
         }

         private void button4_Click(object sender, System.EventArgs e)
         {
             OpenFileDialog fileBrowserDlg = new OpenFileDialog();
             //folderBrowserDlg.ShowNewFolderButton = true;
             //folderBrowserDlg.SelectedPath = _filelistlocation;
             fileBrowserDlg.FileName = textBox1.Text;
             DialogResult dlgResult = fileBrowserDlg.ShowDialog();
             if (dlgResult.Equals(DialogResult.OK))
             {
                 textBox1.Text = fileBrowserDlg.FileName;
                 File_existence.Properties.Settings.Default.Save();
                 // Environment.SpecialFolder rootFolder = folderBrowserDlg.RootFolder;
             }
         }

         private void button5_Click(object sender, System.EventArgs e)
         {
             if (!textBox1.Text.Equals(String.Empty))
             {
                 if (System.IO.Directory.GetFiles(textBox1.Text).Length > 0)
                 {
                     foreach (string file in System.IO.Directory.GetFiles(textBox1.Text))
                     {
                         checkedListBox1.Items.Add(file);
                     }
                 }
                 else
                 {
                     checkedListBox1.Items.Add(String.Format("No file found: {0}", textBox1.Text));
                 }
             }
         }
    }
}

我需要做的任务是，通常需要将显示在选中列表框中的文件移动或复制到另一个目录。这很好，因为我已经可以用我编码的内容做到这一点，但它的作用是它将移动或复制选中列表框中的所有文件。我想要做的是让用户只能通过选中选中的列表框来选择要移动或复制的文件，以便只移动或复制这些文件。

编辑：是否可以检查列表框。检查项目？
