解决方案:
此问题是由于未在 Program.cs 中加载 CefRuntime 引起的。只需将示例文件中的所有代码复制到您的 Program.cs。
然后,如果您的 CefWebBrowser 卡住并且有“旋转的等待鼠标光标”,则设置 SingleProcess = true。
原因是如果浏览器是从识别的二级进程调用的,整个进程都会被阻塞,直到进程结束。
问题:
任何人都有在 WinForm 中使用 CEF(Chromium Embedded Framework)的经验?
这个组件折磨了我一整天。我不能让它工作。它只是没有出现。
所以我的问题是:如何在 WinForm 应用程序中使用 CEF?
我确实检查了论坛,但令人惊讶的是没有人问这个问题。看来我是唯一一个不知道如何使用它的笨人。
public partial class Form1 : Form
{
private CefWebBrowser cefwbShell = null;
//private readonly SynchronizationContext _pUIThread;
private void Form1_Load(object sender, EventArgs e)
{
cefwbShell.Visible = true;
cefwbShell = new CefWebBrowser { StartUrl = "http://example.com" };
cefwbShell.Parent = this;
cefwbShell.Dock = DockStyle.Fill;
cefwbShell.BringToFront();
cefwbShell.Show();
}
}
更新:
我正在尝试使用Xilium.CefGlue
. 在我复制了正确版本的发布 dll(991)后,我得到了一个异常:
InvalidOperationException was unhandlled by user code
Failed to create browser.

更新 2:
private void Create()
{
var page = new TabPage("New Tab");
page.Padding = new Padding(0, 0, 0, 0);
var browser = new CefWebBrowser();
browser.StartUrl = startUrl;
browser.Dock = DockStyle.Fill;
browser.TitleChanged += (s, e) =>
{
BeginInvoke(new Action(() =>
{
var title = browser.Title;
if (tabControl.SelectedTab == page)
{
Text = browser.Title + " - " + _mainTitle;
}
page.ToolTipText = title;
if (title.Length > 18)
{
title = title.Substring(0, 18) + "...";
}
page.Text = title;
}));
};
browser.AddressChanged += (s, e) =>
{
BeginInvoke(new Action(() =>
{
addressTextBox.Text = browser.Address;
}));
};
browser.StatusMessage += (s, e) =>
{
BeginInvoke(new Action(() =>
{
statusLabel.Text = e.Value;
}));
};
page.Controls.Add(browser);
tabControl.TabPages.Add(page);
tabControl.SelectedTab = page;
}
