只有一个comboBox的表单:在这里输入图像描述

和D驱动器中的MyTest文件夹，您可以找到Folder1, Folder2, Folder3在这里输入图像描述

我想在文件夹MyTest中观察任何添加的.txt文件，如果在comboBox中选择了Folder1，则将它们移动到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));
        }
    }

使用filewatcher将文件发送到特定文件夹

您可以像下面这样实现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);
    }
}

移动文件

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");
}
