Question

我创建了一个虚拟DLL。我原以为我可以访问命名空间中的S1。我可以看到我的函数，我可以在它的exe形式中看到带有il dasm的结构。

using System.IO;

namespace emitTest
{
    class Program
    {
        static void Main(string[] args)
        {
            AssemblyName assemblyName = new AssemblyName();
            assemblyName.Name = "HelloWorld";
            AssemblyBuilder assemblyBuilder = Thread.GetDomain().DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);
            ModuleBuilder module;
            module = assemblyBuilder.DefineDynamicModule("HelloWorld.exe", true);
            TypeBuilder typeBuilder = module.DefineType("MyNamespace.HelloWorldType", TypeAttributes.Public | TypeAttributes.Class);
            MethodBuilder methodbuilder = typeBuilder.DefineMethod("Main", MethodAttributes.HideBySig | MethodAttributes.Static | MethodAttributes.Public, typeof(void), new Type[] { typeof(string[]) });
            var s1 = module.DefineType("Space.S1", TypeAttributes.Public | TypeAttributes.Sealed |  TypeAttributes.AnsiClass | TypeAttributes.SequentialLayout | TypeAttributes.BeforeFieldInit, typeof(System.ValueType));
            s1.DefineField("a", typeof(int), FieldAttributes.Public);
            s1.CreateType();
            ILGenerator ilGenerator = methodbuilder.GetILGenerator();
            ilGenerator.Emit(OpCodes.Ret);
            Type helloWorldType = typeBuilder.CreateType();
            if (false)
            {
                // set the entry point for the application and save it
                assemblyBuilder.SetEntryPoint(methodbuilder, PEFileKinds.ConsoleApplication);
                assemblyBuilder.Save("HelloWorld.exe");
            }
            else
            {
                assemblyBuilder.SetEntryPoint(methodbuilder, PEFileKinds.Dll);
                assemblyBuilder.Save("HelloWorld.dll");
            }
        }
    }
}

我不确定我明白你究竟在问什么，但我认为问题在于你总是将模块定义为HelloWorld.exe。您需要做的是确保模块名称与文件名匹配。

因此，如果要将程序集保存为HelloWorld.dll，则需要将模块名称设置为HelloWorld.dll。

IL Generator创建时无DLL访问
