C# Winforms，CefSharp：基本身份验证的身份验证弹出窗口不显示
我正在WinForms应用程序中添加cefsharp。我们的网站使用基本身份验证进行访问，但CefSharp不会显示弹出窗口。我发现了，但是VisualStudio没有实现该接口，并且抱怨AuthDialog是一个未知类。我来自Java方面，不太了解Winforms中的类，但我找不到AuthDialog。我做错了什么 代码：C# Winforms，CefSharp：基本身份验证的身份验证弹出窗口不显示,c#,winforms,cefsharp,C#,Winforms,Cefsharp,我正在WinForms应用程序中添加cefsharp。我们的网站使用基本身份验证进行访问，但CefSharp不会显示弹出窗口。我发现了，但是VisualStudio没有实现该接口，并且抱怨AuthDialog是一个未知类。我来自Java方面，不太了解Winforms中的类，但我找不到AuthDialog。我做错了什么 代码： bool IRequestHandler.GetAuthCredentials(IWebBrowser browser, bool isProxy, string hos

您需要通过nuget packager添加对CefSharp的引用。您可以从
工具->nuget package ManagerInstall-Package CefSharp.WinForms -Version 63.0.3
对于AuthDialog，我假设您在应用程序的某个地方创建了一个表单。需要添加的名称空间。如果没有这样的表单，您需要创建一个用户可以提供用户名和密码的表单。您需要通过nuget packager添加对CefSharp的引用。您可以从
