发布无法加载文件或程序集 CefSharp.Core.dll

Question

我在我的 C# Windows 窗体应用程序中使用 CefSharp，当我从 Visual Studio 运行它时它运行良好，但是当我使用 FTP 帐户作为发布文件夹和 url 作为安装文件夹 url 发布它时

但我收到以下错误，

我按照手册中的所有内容将所需文件复制到 bin 文件夹中 （CefSharp.BrowserSubprocess.Core.dll、CefSharp.BrowserSubprocess.exe、CefSharp.Core.dll、CefSharp.dll、CefSharp.WinForms.dll、icudtl.dat、libcef.dll）

不幸的是，没有任何效果，问题出在哪里？

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Answer 1

我设法将Here 提到的所有需要​​的文件收集到一个文件夹中，并将其命名为 dll，然后我将其放入 packages 文件夹中

现在在 .csproj 和 </Project> 之前我添加了

  <ItemGroup>
    <Content Include="$(SolutionDir)packages\dll\**\*.*">
      <Link>%(RecursiveDir)%(Filename)%(Extension)</Link>
      <Visible>false</Visible>
    </Content>
  </ItemGroup>

发布后应用磨损并解决

Answer 2

我有点晚了，但在这里补充一下，我使用以下解决方案来解决将 CEFSharp 文件移动到子文件夹中的问题。 （感谢https://gist.github.com/BlackBooth/19ce027c4f68c1eb4fc1144988ca6662）

using CefSharp;
using System;
using System.IO;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Windows.Forms;

namespace TestApp
{
    internal static class Program
    {
        // The subfolder, where the cefsharp files will be moved to
        private static string cefSubFolder = "CEFSharp";
        // If the assembly resolver loads cefsharp from another folder, set this to true
        private static bool resolved = true;

        [STAThread]
        private static void Main()
        {
            AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;

            InitializeCefSharp();

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MainForm());
        }

        [MethodImpl(MethodImplOptions.NoInlining)]
        private static void InitializeCefSharp()
        {
            var settings = new CefSettings();
            
            // Set BrowserSubProcessPath when cefsharp moved to the subfolder
            if (resolved)
                settings.BrowserSubprocessPath = Path.Combine(Application.StartupPath, cefSubFolder, "CefSharp.BrowserSubprocess.exe");

            // Make sure you set performDependencyCheck false
            Cef.Initialize(settings, shutdownOnProcessExit: true, performDependencyCheck: false);
        }

        /// <summary>
        /// Will attempt to load missing assemblys from subfolder
        /// </summary>
        private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
        {
            if (args.Name.StartsWith("CefSharp"))
            {
                resolved = true; // Set to true, so BrowserSubprocessPath will be set

                string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll";
                string subfolderPath = Path.Combine(Application.StartupPath, cefSubFolder, assemblyName);
                return File.Exists(subfolderPath) ? Assembly.LoadFile(subfolderPath) : null;
            }

            return null;
        }
    }
}

然后在 Visual Studio 中我使用以下构建事件。

预编译：

RD /S /Q "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"

后期构建：

dir /b /a-d "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\"|findstr /b "$(TargetName)" >"%temp%\searchfiles.tmp"

mkdir CEFSharp

xcopy "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp" /exclude:%temp%\searchfiles.tmp /y

cd  "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\"

attrib +r $(TargetName).*
del /q *
attrib -r $(TargetName).*

move "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\locales" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"

move "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\swiftshader" "$(ProjectDir)bin\$(PlatformName)\$(ConfigurationName)\CEFSharp"

更好的是，@amaitland 建议修改您的项目以在 CefSharp 目标之前包含 CefSharpTargetDir，并且文件将作为构建的一部分复制到子文件夹中。见：https://github.com/cefsharp/CefSharp/blob/cefsharp/83/NuGet/CefSharp.Common.targets#L12

 <PropertyGroup>
    <CefSharpTargetDir Condition=" '$(CefSharpTargetDir)' == '' ">CEFSharp</CefSharpTargetDir>
  </PropertyGroup>
