Summary

The Module32First API

C# Signature:

[DllImport("kernel32.dll")]
static extern bool Module32First(IntPtr hSnapshot, ref MODULEENTRY32 lpme);

User-Defined Types:

See struct MODULEENTRY32

Notes:

None.

Sample Code:

For example:

    ----------------
    int procIDDDDDDDDDDDDD = Process.GetCurrentProcess().Id;
    ----------------
    static void EnumProcessModules(int procIDDDDDDDDDDDDD)
    {//http://pastebin.com/BzD1jdmH
        var snapshot = CreateToolhelp32Snapshot(SnapshotFlags.Module | SnapshotFlags.Module32, (uint)procIDDDDDDDDDDDDD);
        MODULEENTRY32 mod = new MODULEENTRY32() { dwSize = (uint)Marshal.SizeOf(typeof(MODULEENTRY32)) };
        if (!Module32First(snapshot, ref mod))
        return;

        List<string> modules = new List<string>();
        do
        {
        modules.Add(mod.szModule);
        }
        while (Module32Next(snapshot, ref mod));
        Console.WriteLine("OK");
    }

Alternative Managed API:

System.Diagnostics.Process class contains many module, process, and thread methods.

For example:

    using System.Diagnostics;
    ...
    private void DumpModuleInfo(IntPtr hProcess)
    {
    uint pid = Process.GetProcessById(hProcess).Id;
    foreach (Process proc in Process.GetProcesses())
    {
        if (proc.Id == pid)
        {
        foreach (ProcessModule pm in proc.Modules)
        {
        Console.WriteLine("{0:X8} {1:X8} {2:X8} {3}", (int)pm.BaseAddress,
        (int)pm.EntryPointAddress, (int)pm.BaseAddress + pm.ModuleMemorySize, pm.ModuleName);
        }
        }
    }
    }
