How to use reflection in C# to extract class and method information from executable file(.exe)

I have .exe file generated via visual studio. Now, in a reversed way, I need to get classes info (namespace and class name) and method info (access modifier, return type, and input parameters) from .exe file.

Actually I could get those info from dll files, but no idea from executable files.

Could anyone give me a simple code demo? Thanks in advance!!

There is no difference between dll and exe files. They are both .NET assemblies. Just use the same code / approach, which you use for DLLs.

You need to use Assembly.LoadFile to load an Assembly from EXE or DLL file:

var assembly = Assembly.LoadFile("C:\path_to_your_exe\YourExe.exe");

foreach (var type in assembly.GetTypes())
{
    Console.WriteLine($"Class {type.Name}:");
    Console.WriteLine($"  Namespace: {type.Namespace}");
    Console.WriteLine($"  Full name: {type.FullName}");

    Console.WriteLine($"  Methods:");
    foreach (var methodInfo in type.GetMethods(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance))
    {
        Console.WriteLine($"    Method {methodInfo.Name}");

        if (methodInfo.IsPublic)
            Console.WriteLine($"      Public");

        if (methodInfo.IsFamily)
            Console.WriteLine($"      Protected");

        if (methodInfo.IsAssembly)
            Console.WriteLine($"      Internal");

        if (methodInfo.IsPrivate)
            Console.WriteLine($"      Private");

        Console.WriteLine($"      ReturnType {methodInfo.ReturnType}");
        Console.WriteLine($"      Arguments {string.Join(", ", methodInfo.GetParameters().Select(x => x.ParameterType))}");
    }
}
