Question

The depends.exe tool can walk thru all the dll’s that the executable depends to, but if the DLL is loaded by the Assembly class dynamically at runtime, how can I see the already loaded DLLs(assemblies)?

Answer 1

As a snapshot:

AppDomain.CurrentDomain.GetAssemblies()

As they happen:

AppDomain.CurrentDomain.AssemblyLoad

Something like:

static void Main()
{
    AppDomain.CurrentDomain.AssemblyLoad += AssemblyLoad;
    LogCurrent("before");
    AnotherMethod();
    LogCurrent("after");
}
static void AnotherMethod()
{
    // to force stuff to happen
    new System.Data.SqlClient.SqlCommand().Dispose(); 
}
static void LogCurrent(string caption)
{
    foreach (Assembly asm in AppDomain.CurrentDomain.GetAssemblies())
    {
        Console.WriteLine(caption + ": " + asm.FullName);
    }
}

static void AssemblyLoad(object sender, AssemblyLoadEventArgs args)
{
    Console.WriteLine("Loaded: " + args.LoadedAssembly.FullName);
}
