What are the different ways to know which all classes and methods present in a DLL?
I suspect the interviewer was referring to reflection. For example: var assembly = ...; // e.g. typeof(SomeType).Assembly var types = assembly.GetTypes(); var methods = types.SelectMany(type => type.GetMethods()); // etc You'd need to filter the types using Type.IsClass to get just the classes, for example. LINQ is very useful when working...
Call Delphi XE6 unicode dll from C# asp.net
BadImageFormatException typically indicates a bitness mismatch. Your Delphi module is 64 bit and the C# module is 32 bit, or vice versa. You have other problems. At least the following: You cast a UTF-16 UnicodeString string to PAnsiChar. That cast is not correct. You return a the address of a...
Is it possible to create instances of all classes in an assembly?
The simple solution will be using .NET Activator class. It is using reflection but since you want create this object for testing purposes I don't think that overhead will make difference for you. You can use Activator like this: Type type = typeof(SomeClass); object obj = Activator.CreateInstance(type); If you need...

Loading an assembly from a dll's Byte array
powershell,dll,.net-assembly,7zip
The library is using Reflection to find its own path via Assembly.GetExecutingAssembly().Location and initializing some static fields with this value. See the source code: private static string _libraryFileName = ConfigurationManager.AppSettings["7zLocation"] ?? Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "7z.dll"); However, if you load an assembly directly from a byte array, the Location is null and GetDirectoryName...

Intermittent Access Violation when using C# to access C++ DLL

And set the CallingConvention = CallingConvention.Cdecl like [DllImport("Test.dll", EntryPoint = "Test", CallingConvention = CallingConvention.Cdecl, ExactSpelling = true)] Note that there is code other than your method that could be executed.

How to free memory in C# that is allocated in C++

You need to call the corresponding "free" method in the library you're using. Memory allocated via new is part of the C++ runtime, and calling FreeHGlobal won't work. You need to call (one way or the other) delete[] against the memory. If this is your own library then create a...

'The command line is too long' when linking .obj files in Windows command prompt
I think I got the answer to my question. I can bundle the arguments of the command in an .rsp file and fire it up on my command prompt with the executable after prepending its path by '@'. So, for this command: cl.exe foo.dll (around 1500 .obj files) (couple of...
Including library in AIR Native Extension causes the error, “The extension context does not have a method with the name…” for all methods
Using ProcessMonitor, I found that the the third-party library has a dependency on an external dll, which it was not finding.

Compiling standalone Qt application using MinGW
I solved my problem now.

System.Windows.Interactivity must be referenced in the main project

When is it a good idea to make a DLL file
What you are after is code reusability, which is a broader subject than making DLL's, which as @Jodrell said, is created when you compile an assembly. The idea of re using code is something which spans across multiple domains and is not thus strictly related to the .NET platform. You...

No, you do not need __declspec(dllexport), when building a DLL with MinGW; (in fact, I frequently omit it myself). The caveat is that, if just one symbol to be included in the DLL is so decorated, then all others you wish to have exported must be likewise decorated, (unless you...

Linking to a static lib compiled with MSVC
Ok, a few things. First of all, there's no such thing as a "static DLL": a DLL is a dynamically linked library. Secondly, Rust uses the MinGW toolchain and runtime. Mixing MSVC and MinGW runtimes can cause odd things to happen, so it's probably best avoided if at all possible....
When to free a dll after exporting object
