CefSharp Visual Studio 2022

Question

如果站点提供下载文件，我如何添加到此代码 CefSharp，它下载到文件夹

C:/Gwlo/Common

，如果没有文件夹，它会创建它？下载后还打开这个文件吗？我只是没有在任何论坛上找到这个问题

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;
using CefSharp.Wpf;

namespace KaindLauncher
{
    public partial class Kaind : Form
    {
        public Kaind()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            chromiumWebBrowser1.Load("https://google.com");
        }

        private void chromiumWebBrowser1_LoadingStateChanged(object sender, CefSharp.LoadingStateChangedEventArgs e)
        {
        }
    }
}

我试过这段代码，但出现错误：

string downloadFolderPath = @"C:\Kaind\Downloads\Common\";

if (!Directory.Exists(downloadFolderPath))
{
    Directory.CreateDirectory(downloadFolderPath);
}

var settings = new DownloadSettings
{
    DefaultFileName = "downloaded_file",
    SaveFileDialog = new SaveFileDialog()
    {
        InitialDirectory = downloadFolderPath,
        OverwritePrompt = true
    }
};

chromiumWebBrowser1.DownloadHandler = new DownloadHandler(settings);
