Question

我正在尝试复制从OpenFileDialog中选择的文件，并将其路径保存到ListBox中。
我希望它从ListBox的路径复制到特定文件夹。
到目前为止，它正在将整个源文件夹复制到目标文件夹中。

我的代码：

private void button1_Click(object sender, EventArgs e)
{
    System.IO.Stream myStream;
    OpenFileDialog thisDialog = new OpenFileDialog();

    thisDialog.InitialDirectory = "c:\\";
    thisDialog.Filter = "All files (*.*)|*.*";
    thisDialog.FilterIndex = 2;
    thisDialog.RestoreDirectory = true;
    thisDialog.Multiselect = true;
    thisDialog.Title = "Please Select Attachments!";

    if (thisDialog.ShowDialog() == DialogResult.OK)
    {
        foreach (String file in thisDialog.FileNames)
        {
            try
            {
                if ((myStream = thisDialog.OpenFile()) != null)
                {
                    using (myStream)
                    {
                        listBox1.Items.Add(file);
                    }
                }
            }

            catch (Exception ex)
            {
                MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
            }
        }
    }
    else
    {
        //do nothing
    }
    //after selecting the files into the openfile dialog proceed to action the below.

    foreach (object item in listBox1.Items)
    {
        //MessageBox.Show(string.Format("{0}!", listBox1.ToString()));
        MessageBox.Show(item.ToString());
        string sourceFolder = item.ToString();
        string destinationFolder = @"c:\\testing";

        //DirectoryInfo directory = new DirectoryInfo(sourceFolder);
        DirectoryInfo directoryName = new DirectoryInfo( Path.GetDirectoryName(sourceFolder));

        FileInfo[] files = directoryName.GetFiles();
        foreach (var file in files)
        {
            string destinationPath = Path.Combine(destinationFolder, file.Name);
            File.Copy(file.FullName, destinationPath);
        }
    }
}

欢迎任何帮助。谢谢。

您正在读取整个源目录的次数是在文件选择器中选择的文件的次数，但是您在ListBox中已经拥有文件的完整路径，您可以简单地遍历它们并复制它们到目的地：

string destinationFolder = @"c:\testing";
foreach (var item in listBox1.Items)
{
    string sourcePath = item.ToString();
    string fileName = Path.GetFileName(sourcePath);
    string destinationPath = Path.Combine(destinationFolder, fileName);
    File.Copy(sourcePath, destinationPath);
}

将文件从列表框的路径复制到特定文件夹
