C# 在webbrowser中嵌入Youtube视频。对象没有'；不支持属性或方法

Youtube最近停止支持以www.Youtube.com/v/{key}格式嵌入的视频。所以我试图将视频从“/v/”转换为“/embed/”。但是，当我尝试导航到视频时，会弹出以下错误：

我使用以下命令导航到该网页：

WPF

为什么仅仅通过从“/v/”切换到“/embed/”就无法做到这一点？如何解决这个问题？

尝试将您的WebBrowser设置为“静默模式”（忽略这些脚本错误）。 它需要一些黑色的IE/COM魔法，但它是有效的

请参见如何执行此操作。

这是现有SO线程的副本

线程中有很多答案，并带有实际代码

最好的建议是在

HKEY\u LOCAL\u MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE\u BROWSER\u EMULATION中为你的
app.exe
设置一个非常高的

我将其设置为
20000
，这可以安全地假设在很多即将推出的版本中都可以使用，并且可以使用最新版本。这种情况很容易在设置exe的过程中完成。因此，您不必担心哪个版本存在，哪个版本不存在。嵌入工作所需的最低版本是IE9

另外，另一个选择是根本不使用嵌入式IE。相反，使用铬。有一个CefSharp项目用于相同的


此项目允许您在WinForms或WPF应用程序中嵌入chromium浏览器。这个应用程序非常简单

using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;

namespace WindowsFormsApp2
{
    public partial class Form1 : Form
    {
        ChromiumWebBrowser chrome;

        private void InitChrome()
        {
            CefSettings settings = new CefSettings();
            Cef.Initialize(settings);
            chrome = new ChromiumWebBrowser("https://www.youtube.com/embed/v2fDTOdWuQQ?rel=0&showinfo=0");
            this.Controls.Add(chrome);
            chrome.Dock = DockStyle.Fill;
        }
        public Form1()
        {
            InitializeComponent();
            InitChrome();
            //this.webBrowser1.Navigate("https://www.youtube.com/embed/v2fDTOdWuQQ?rel=0&showinfo=0");
        }

    }
}

而且效果很好。这将使您的应用程序不依赖于目标计算机上安装的浏览器

使用WebBrowser.NavigateToString代替WebBrowser.Navigate并使用HTML代替URL。

WPF有一个“浏览器仿真”功能来解决这类问题

添加下面的枚举

public enum BrowserEmulationVersion
{
    Default = 0,
    Version7 = 7000,
    Version8 = 8000,
    Version8Standards = 8888,
    Version9 = 9000,
    Version9Standards = 9999,
    Version10 = 10000,
    Version10Standards = 10001,
    Version11 = 11000,
    Version11Edge = 11001
}

创建一个新类“InternetExplorerBrowserEmulation”，并在其中添加以下代码

public class InternetExplorerBrowserEmulation
{
    private const string InternetExplorerRootKey = @"Software\Microsoft\Internet Explorer";
    private const string BrowserEmulationKey = InternetExplorerRootKey + @"\Main\FeatureControl\FEATURE_BROWSER_EMULATION";

            RegistryKey key;

            key = Registry.LocalMachine.OpenSubKey(InternetExplorerRootKey);

            if (key != null)
            {
                object value;

                value = key.GetValue("svcVersion", null) ?? key.GetValue("Version", null);

                if (value != null)
                {
                    string version;
                    int separator;

                    version = value.ToString();
                    separator = version.IndexOf('.');
                    if (separator != -1)
                    {

        return result;

    public static bool IsBrowserEmulationSet()
    {
        return GetBrowserEmulationVersion() != BrowserEmulationVersion.Default;

在设置URL之前，我们需要添加以下代码

if (!InternetExplorerBrowserEmulation.IsBrowserEmulationSet())
{
  InternetExplorerBrowserEmulation.SetBrowserEmulationVersion();
}
