使用代码如何将附属程序集嵌入到csharptest.net 提供的 EXE 文件中,我创建了一个自定义程序集解析器并将我的程序集嵌入到我的资源中。

我可以成功解决我使用的程序集,但不知何故 AppDomain.CurrentDomain.AssemblyResolve 要求一个名为“AppName.resources”的程序集,特别是“MyProgram.resources,Version=0.15.3992.31638,Culture=en-US,PublicKeyToken=null”,我不知道不知道怎么解决?

我试图禁用从资源加载我的自定义程序集(将我所有的程序集 dll 放在程序目录中)并且刚刚启用 AppDomain.CurrentDomain.AssemblyResolve,但它仍然要求它。

我对此有点困惑,如果您能帮助我,将不胜感激。

这是我感兴趣的代码;

static Assembly ResolveAssemblies(object sender, ResolveEventArgs args)
{
    Assembly assembly = null;
    string name = args.Name.Substring(0, args.Name.IndexOf(','));
    if (name == "MyProgram.resources") return null;
    else name = string.Format("MyProgram.Resources.Assemblies.{0}.dll", name);

    lock (_loadedAssemblies)
    {
        if (!_loadedAssemblies.TryGetValue(name, out assembly))
        {
            using (Stream io = Assembly.GetExecutingAssembly().GetManifestResourceStream(name))
            {
                if (io == null)
                {
                    MessageBox.Show("MyProgram can not load one of it's dependencies. Please re-install the program", string.Format("Missing Assembly: {0}", name), MessageBoxButtons.OK, MessageBoxIcon.Error);
                    Environment.Exit(-1);
                }
                using (BinaryReader binaryReader = new BinaryReader(io))
                {
                    assembly = Assembly.Load(binaryReader.ReadBytes((int)io.Length));
                    _loadedAssemblies.Add(name, assembly);
                }
            }
        }
    }

    return assembly;
}

我自己回答;

将此行添加到 AssemblyInfo.cs 即可解决此问题,并且解析器将不再被要求提供资源。

[assembly: NeutralResourcesLanguageAttribute("en-US", UltimateResourceFallbackLocation.MainAssembly)]

虽然这是一种变通方法,但应仔细考虑多语言应用程序。

更多信息:

对于具有非美国文化的机器,这种方法失败了。更好的方法是忽略程序集解析器上的资源;

public Assembly Resolver(object sender, ResolveEventArgs args)
        {
            lock (this)
            {
                Assembly assembly;
                AssemblyName askedAssembly = new AssemblyName(args.Name);

                string[] fields = args.Name.Split(',');
                string name = fields[0];
                string culture = fields[2];
                // failing to ignore queries for satellite resource assemblies or using [assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.MainAssembly)] 
                // in AssemblyInfo.cs will crash the program on non en-US based system cultures.
                if (name.EndsWith(".resources") && !culture.EndsWith("neutral")) return null;

                /* the actual assembly resolver */
                ...
            }
      }

我的情况有点复杂,上述解决方案对我不起作用。(即更改 AssemblyInfo.cs 文件)

我已将所有表单和图像资源移动到单独的 dll 中,并且在使用任何图像时都会引发“filenotfoundexception”异常。

重要信息如下:
从 .NET Framework 4 开始,为所有程序集(包括资源程序集)引发 ResolveEventHandler 事件。请参阅以下参考

https://msdn.microsoft.com/en-us/library/system.appdomain.assemblyresolve(v=vs.110).aspx

结果证明解决方案非常简单。如果以 'dllname.resources.dll' 形式请求资源文件,则始终返回 null;

这是我从找到的其他示例中改编而来的事件代码。(我已经注释了调试行 - 如果您在使用代码时遇到问题,请取消注释。

在您的课程中添加这一行。它用于防止多次加载 dll

    readonly static Dictionary<string, Assembly> _libs = new Dictionary<string, Assembly>();

这是事件方法。

private static Assembly OnAssemblyResolve(object sender, ResolveEventArgs args)
        {
            Assembly assembly = null;
            string keyName = new AssemblyName(args.Name).Name;
            if (keyName.Contains(".resources"))
            {
                return null;  // This line is what fixed the problem
            }
            if (_libs.ContainsKey(keyName))
            {
                assembly = _libs[keyName]; // If DLL is loaded then don't load it again just return
                return assembly;
            }

            string dllName = DllResourceName(keyName);
            //string[] names = Assembly.GetExecutingAssembly().GetManifestResourceNames();   // Uncomment this line to debug the possible values for dllName
            using (Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(dllName))
            {
                if (stream == null)
                {
                    Debug.Print("Error! Unable to find '" + dllName + "'");
                    // Uncomment the next lines to show message the moment an assembly is not found. (This will also stop for .Net assemblies
                    //MessageBox.Show("Error! Unable to find '" + dllName + "'! Application will terminate.");
                    //Environment.Exit(0);
                    return null;
                }

                byte[] buffer = new BinaryReader(stream).ReadBytes((int) stream.Length);
                assembly = Assembly.Load(buffer);

                _libs[keyName] = assembly;
                return assembly;
            }
        }

        private static string DllResourceName(string ddlName)
        {
            if (ddlName.Contains(".dll") == false) ddlName += ".dll";

            foreach (string name in Assembly.GetExecutingAssembly().GetManifestResourceNames())
            {
                if (name.EndsWith(ddlName)) return name;
            }
            return ddlName;
        }
