Loading plug-in DLL files, “The invoked member is not supported in a dynamic assembly.”

阅读更多关于 Loading plug-in DLL files, “The invoked member is not supported in a dynamic assembly.”

问题 We have custom DLL's that are not included in our initial setup file. They are loaded at runtime. This process worked fine while using .NET 2.0, but we are getting the "The invoked member is not supported in a dynamic assembly" error message now that we are using .NET 4.0. try { assem = Assembly.LoadFrom(fi.FullName); //fi is FileSystemInfo } catch (FileLoadException) {} catch (BadImageFormatException) {} catch (System.Security.SecurityException) {} catch (ArgumentException) {} catch

Can I specify dependency directories when dynamically loading assemblies?

阅读更多关于 Can I specify dependency directories when dynamically loading assemblies?

问题 I'm wondering if a setup like this is possible: c:\eflow\proxy.dll (main DLL loaded by application) c:\eflow\application\dynamic.dll (DLL dynamically loaded by proxy.dll) c:\eflow\dependency.dll (dependent DLL required by dynamic.dll) Basically, I'd like to dynamically load a DLL (to instantiate classes, etc) but have that DLL's dependencies stored in a different location. Is this possible? I don't want to have a copy of these dependent DLLs in every sub-directory... (and I can't load them in

Release .dll and .pdb after loading .dll file dynamically

问题 I'm building a windows application where I can call coded UI project (project named RecordAndPlayback) by clicking on a button. My aim is to call the test methods in the coded UI project and then be able to modify the test then call it back from my win app without closing it using the same button. I managed to call the test method, but I have a problem in modifying the test method after that. Whenever I build my coded UI project, I get an error ERROR CSC(0,0): Unexpected error creating debug

问题 I was recently asked if I knew anything about Dynamic Assemblies in .Net. The short answer was - I don't. I have found plenty of articles that describe how to create a dynamic assembly but none that truely explain the following: What they are (other than they are run directly from memory) What advantages they provide over static assemblies Real world examples of their usage Any explanations to the above would be very much appreciated. Many thanks. 回答1: This article is a bit dated and the code

When can a dynamic module have a type load exception?

阅读更多关于 When can a dynamic module have a type load exception?

问题 I have a dynamic module which gets types added to it as my application runs. The module is created via the following code: var assemblyName = new AssemblyName("MyAssembly"); var assemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run); MyClass.RuntimeBoundDerivedTypesModule = assemblyBuilder.DefineDynamicModule("MainModule"); Other parts of the application also sometimes call GetTypes() on the module's assembly. Occasionally, when this happens I

How to save a dynamically generated assembly that is stored in-memory?

阅读更多关于 How to save a dynamically generated assembly that is stored in-memory?

问题 I want to get my hands on an assembly by saving it to disc or reflect it at runtime. The assembly is generated dynamically in memory by third party. Does anyone know how to do this? 回答1: Try this (found here): byte[] dllAsArray; using (MemoryStream stream = new MemoryStream()) { BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, results.CompiledAssembly); dllAsArray = stream.ToArray(); } 回答2: It's been a while since I did this, I'm guessing that the program that

How to Save an Expression Tree as the Main Entry Point to a New Executable Disk File?

问题 I'm trying to export an expression tree to a PE assembly as the main entry point. I've acquired a Lambda Expression through building an expression tree, for example: using System.Linq; using System; // 1. use expression trees to create a block expression (not shown) // 2. create a lambda expression: LambdaExpression exprLambda = Expression.Lambda(exprBlock, new ParameterExpression[0]); MethodBuilder mbuilder = null; // 3. ??? Somehow get a method builder instance that works ??? // 4. Compile

Using Roslyn Emit method with a ModuleBuilder instead of a MemoryStream

阅读更多关于 Using Roslyn Emit method with a ModuleBuilder instead of a MemoryStream

I was having trouble with performance when using Roslyn to compile to a dynamic assembly. Compilation was taking ~3 seconds, compared to ~300 milliseconds to compile the same code when using the CodeDom compiler. Here's a pared-down version of the code I'm using to do the compilation: var compilation = CSharpCompilation.Create( "UserPayRules.dll", syntaxTrees, assembliesToAdd); using (var stream = new MemoryStream()) { stopWatch.Start(); var result = compilation.Emit(stream); stopWatch.Stop(); Debug.WriteLine("Compilation: {0}", stopWatch.ElapsedMilliseconds); if (!result.Success) { throw new
