How do I detect the DLLs required by an application?

Question

In a nutshell: I want to do the same thing \"Dependency Walker\" does.

Is there any Win32 API function which can enumerate the dependencies of a EXE and/or DLL file?

You can write a console app to wrap this up, create a PowerShell script with it or, like I usually end up doing since I only have to do it once in a blue moon, add the following to your code for a quick check:

    private static HashSet<string> ReferencedAssemblies = new HashSet<string>();

    ...
    OutputDependencies(Assembly.GetAssembly(typeof(Program)), 0);
    ...

    static void OutputDependencies(Assembly assembly, int indent)
    {
        if (assembly == null) return;

        Console.WriteLine(new String(' ', indent * 4) + assembly.FullName);
        if (!ReferencedAssemblies.Contains(assembly.FullName))
        {
            ReferencedAssemblies.Add(assembly.FullName);

            foreach (var childAssembly in assembly.GetReferencedAssemblies())
            {
                OutputDependencies(Assembly.Load(childAssembly.FullName), indent + 1);
            }
        }
    }
