我知道System.Diagnostics中有一个process.Modules列表,其中包含一些过程模块,但由于在这里找不到一些dll而遇到了一些麻烦:
Process process = Memory.GetProcessByName("csgo");
foreach (ProcessModule pm in process.Modules)
Console.WriteLine(pm.ModuleName);
所以我一直在寻找一种解决方案来使它起作用,我在pinvoke.net上发现了一些有趣的东西,但它也没有起作用:
var snapshot = CreateToolhelp32Snapshot(SnapshotFlags.Module, (uint)process.Id);
MODULEENTRY32 mod = new MODULEENTRY32() {
dwSize = (uint)Marshal.SizeOf(typeof(MODULEENTRY32))
};
if (!Module32First((IntPtr)snapshot, ref mod))
return;
do { Console.WriteLine(mod.szModule); } while (Module32Next((IntPtr)snapshot, ref mod));
然后我搜索了C ++中相同代码的实现,并且有效
#include <windows.h>
#include <iostream>
#include <TlHelp32.h>
#include <string>
#include <sstream>
using namespace std;
int main() {
int a;
cin >> a;
HANDLE snapshot = CreateToolhelp32Snapshot(0x00000008, a);
MODULEENTRY32 mod;
mod.dwSize = sizeof(mod);
if (!Module32First(snapshot, &mod))
return 0;
do { cout << mod.szModule << endl; } while (Module32Next(snapshot, &mod));
system("pause");
return 0;
}
所以我的问题是:第二个和第三个变体之间有什么区别,我该如何使其在C#中工作?我还尝试过使用user32.dll中的OpenProcess()和kernel32.dll中的GetModuleHandle(),但这没有用。
答案 0 :(得分:0)
您必须将代码编译为x64并以管理员身份运行才能获取所有模块。
或者将其用作快照类型:
TH32CS_SNAPMODULE | TH32CS_SNAPMODULE32
这是C#中CreateToolHelp32Snapshot()模块循环的样子:
const Int64 INVALID_HANDLE_VALUE = -1;
[Flags]
private enum SnapshotFlags : uint
{
HeapList = 0x00000001,
Process = 0x00000002,
Thread = 0x00000004,
Module = 0x00000008,
Module32 = 0x00000010,
Inherit = 0x80000000,
All = 0x0000001F,
NoHeaps = 0x40000000
}
