我目前正在尝试编写一个小型服务,它使用 CefSharp (v57.0.0) 将 HTML 呈现为 PDF 文件,并按照说明在我的项目中使用“任何 CPU”(功能请求 - 添加 AnyCPU 支持)。在我的项目中,我使用了以下似乎工作正常的程序集解析器(它在初始化期间加载 CefSharp.Core.dll、CefSharp.dll):

// Will attempt to load missing assembly from either x86 or x64 subdir
    private static Assembly Resolver(object sender, ResolveEventArgs args)
    {
        if (args.Name.StartsWith("CefSharp", StringComparison.Ordinal))
        {
            string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll";
            string archSpecificPath = Path.Combine(
                AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
                Environment.Is64BitProcess ? "x64" : "x86",
                assemblyName);

            var outputAssembly = File.Exists(archSpecificPath) ? Assembly.LoadFile(archSpecificPath) : null;

            return outputAssembly;
        }

        return null;
    }

对于 CefSharp 的初始化,我设置了与示例中完全相同的值:

var settings = new CefSettings()
        {
            // By default CefSharp will use an in-memory cache, you need to specify a Cache Folder to persist data
            CachePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\\Cache")
        };

        // Perform dependency check to make sure all relevant resources are in our output directory.
        Cef.Initialize(settings, performDependencyCheck: true, browserProcessHandler: null);

但是,如果我开始我的简单测试,我会收到以下错误代码:

Message: System.Exception : Unable to locate required Cef/CefSharp dependencies:
Missing:CefSharp.BrowserSubprocess.exe
Missing:CefSharp.BrowserSubprocess.Core.dll
Missing:CefSharp.Core.dll
Missing:CefSharp.dll
Missing:icudtl.dat
Missing:libcef.dll
Executing Assembly Path:D:\projects\CefService\bin\Debug\x86

有什么想法可能在这里发生以及如何解决问题?

消息很清楚,无法加载其他程序集。

以下是有关如何执行此操作的一些通用说明:

  • LoadLibrary首先使用and加载本地的(例如 libcef.dll)FreeLibrary
  • 查看加载托管的是否会自动加载它所依赖的其他托管的,否则处理它们(乏味)

您可能对这些用于发现依赖项的工具感兴趣:
