如何浏览文件夹

Question

我想设计一个包含浏览按钮的程序,我们可以浏览到所选文件夹并打开文件夹内的文件.

我需要一个参考和阅读,我可以解决我的问题？喜欢我应该使用什么方法/类.我不喜欢从MSDN上读书,因为我很难理解他们的理论.仅供参考我仍然是C#的初学者.

非常感谢你

P/s:这是我从互联网上找到的代码,您可以浏览/创建新文件夹.但我不知道为什么它使用Shell32.dll ..

private void button1_Click(object sender, EventArgs e)
{
    string strPath;
    string strCaption = "Select a Directory and folder.";
    DialogResult dlgResult;
    Shell32.ShellClass shl = new Shell32.ShellClass();
    Shell32.Folder2 fld = (Shell32.Folder2)shl.BrowseForFolder(0, strCaption, 0,
        System.Reflection.Missing.Value);
    if (fld == null)
    {
        dlgResult = DialogResult.Cancel;
    }
    else
    {
        strPath = fld.Self.Path;
        dlgResult = DialogResult.OK;
    }
}

private void button1_Click(object sender, System.EventArgs e)
{
    Stream myStream = null;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();

    openFileDialog1.InitialDirectory = "c:\\" ;
    openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
    openFileDialog1.FilterIndex = 2 ;
    openFileDialog1.RestoreDirectory = true ;

    if(openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        try
        {
            if ((myStream = openFileDialog1.OpenFile()) != null)
            {
                using (myStream)
                {
                    // Insert code to read the stream here.
                }
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
        }
    }
}
