Question

使表单只包含一个组合框：enter image description here

驱动器D中的MyTest文件夹，您可以在其中找到Folder1，Folder2，Folder3 enter image description here

如果在comboBox a.s.o中选择.txt，我想在文件夹MyTest中观看任何已添加的Folder1文件，并将其移至Folder1。

 public void CreateFileWatcher(string path)
        {
        FileSystemWatcher fsw = new FileSystemWatcher("D:\\MyTest");

        fsw.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
            | NotifyFilters.FileName | NotifyFilters.DirectoryName;

        fsw.Changed += new FileSystemEventHandler(OnChanged);

        fsw.Created += new FileSystemEventHandler(OnChanged);

        fsw.Deleted += new FileSystemEventHandler(OnChanged);

        fsw.Error += new ErrorEventHandler(OnError);

        fsw.EnableRaisingEvents = true;

    }

    private static void OnChanged(object source, FileSystemEventArgs e)
    {

    }

    private static void OnError(object source, ErrorEventArgs e)
    {

        Console.WriteLine("The FileSystemWatcher has detected an error");

        if (e.GetException().GetType() == typeof(InternalBufferOverflowException))
        {
           Console.WriteLine(("The file system watcher experienced an internal buffer overflow: " + e.GetException().Message));
        }
    }

Answer 1

您可以实施以下OnChanged事件：

private void OnChanged(object sender, FileSystemEventArgs e)
{
    string destFolder = Path.Combine(@"d:\", comboBox1.SelectedItem.ToString());
    if (!Directory.Exists(destFolder))
    {
        Directory.CreateDirectory(destFolder);
    }
    string destFileName = Path.Combine(destFolder, new FileInfo(e.FullPath).Name);
    try
    {
        File.Move(e.FullPath, destFileName);
    }
    catch (Exception ex)
    {
        Console.WriteLine("File move operation error:" + ex.Message);
    }
}

Answer 2

这就是你将文件移动为

的方式

string sourceFile = @"C:\Users\Public\public\test.txt";
    string destinationFile = @"C:\Users\Public\private\test.txt";

    // To move a file or folder to a new location:
    System.IO.File.Move(sourceFile, destinationFile);

    // To move an entire directory. To programmatically modify or combine
    // path strings, use the System.IO.Path class.
    System.IO.Directory.Move(@"C:\Users\Public\public\test\", @"C:\Users\Public\private");
}

使用filewatcher将文件发送到特定文件夹
