无法从 'System.Management.EnumerationOptions' 转换为 'System.IO.SearchOption

Question

using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.VisualBasic.FileIO;
using System.Management;

namespace test_code
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog folderDlg = new FolderBrowserDialog();
           //folderDlg.ShowDialog();
            if (folderDlg.ShowDialog() != DialogResult.OK)
            {
                return;
            }

            // Has different framework dependend implementations 
            // in order to handle unauthorized access to subfolders
            RenamePngFiles(folderDlg.SelectedPath);
        }
        private void RenamePngFiles(string directoryPath)
        {
            int fileNameSuffixCounter = 1;
            foreach (string originalFullFileName in System.IO.Directory.EnumerateFiles(directoryPath, "*.png", new EnumerationOptions()))
            {
                // The new file name without path
                var newFileName = $"{System.IO.Path.GetFileNameWithoutExtension(originalFullFileName)}#{fileNameSuffixCounter++}{System.IO.Path.GetExtension(originalFullFileName)}";

                FileSystem.RenameFile(originalFullFileName, newFileName);
            }
        }
    }
}

以上是我的代码，我不确定为什么我无法消除上述错误。我尝试了各种名称空间，但我无法摆脱它。我正在使用 .netframework 4.7.2。 如您所见，我要做的就是重命名文件夹中的所有文件，包括子文件夹以附加 # 和一个数字，该数字会根据文件夹中文件的数量不断增加。

结合上面的评论，我做了如下修改

更新：

修改selectedPath中的所有png文件。

RenameAllPngFiles(folderDlg.SelectedPath);

以下为自定义函数:

重命名所有 png 文件：

private void RenameAllPngFiles(string directoryPath) {
    RenameCurrentPng(directoryPath);
    foreach (var item in GetDirectoryInfos(directoryPath)) {
        RenameCurrentPng(item.FullName);
    }
}

重命名当前目录下的所有png文件：

private void RenameCurrentPng(string directoryPath) {
    int fileNameSuffixCounter = 1;
    foreach (string originalFullFileName in Directory.EnumerateFiles(directoryPath, "*.png")) {
        // The new file name without path
        var newFileName = $"{System.IO.Path.GetFileNameWithoutExtension(originalFullFileName)}#{fileNameSuffixCounter++}{System.IO.Path.GetExtension(originalFullFileName)}";
        FileSystem.RenameFile(originalFullFileName, newFileName);
    }
}

获取所有子文件夹的地址:

private DirectoryInfo[] GetDirectoryInfos(string directoryPath) {
    DirectoryInfo di = new DirectoryInfo(directoryPath);
    DirectoryInfo[] directories = di.GetDirectories("*", System.IO.SearchOption.AllDirectories);
    return directories;
}
