How to use Pointer + Offset in C#?

Posts 1–11 of 11 · Page 1 of 1

Question in title ^_^

If your C# stuff is injected, use the Marshal class, such as:

var basePtr = new IntPtr(0x12345678);
var ptrVal = Marshal.ReadIntPtr(basePointer);
Marshal.WriteByte(new IntPtr(ptrVal.ToInt32() + 0x123), 0x90);

If you are externally reading/writing, then use ReadProcessMemory / WriteProcessMemory.
pinvoke.net: readprocessmemory (kernel32)
pinvoke.net: writeprocessmemory (kernel32)

Read the pointer, convert it to an Int32 using BitConverter, then add the offset, read again etc. for each offset.

Thanks this will help

But how I can do this?

So?

ReadProcessMemory(bla, bla, bla);
...
// Add ofsset
WriteProcessMemory(bla, bla, bla);

how to add it(offset)?

Oh you mean so

// Read pointer
return (IntPtr)(BitConverter.ToInt32(memory, 0) + Offset);

As i see you are using External editing...
So:
Pointer + Offset looks like:

Code:

IntPtr Pointer = 0xEACBD int Offset = 0x555 IntPtr PointTo = ReadMem(Pointer) WriteMem(

Code:

PointTo + Offset, 999)

Edit: ^ Vbulletion auto-correction fuck up the post -_-

And with more Offsets?

OM me i ll help u

var buffer          = new byte[4];
var lpOutStorage    = IntPtr.Zero;

// Read the base pointer..
ReadProcessMemory( process.Handle, baseAddress, buffer, (uint)buffer.Length, ref lpOutStorage );

// Loop each offset and read the pointers..
for (int x = 0; x < offsetList.Length - 1; x++)
{
    baseAddress = BitConverter.ToInt32(buffer, 0) + offsetList[x];
    ReadProcessMemory( process.Handle, baseAddress, buffer, (uint)buffer.Length, ref lpOutStorage );
}

// Read the last pointer+offset as the main value..
var valueBuffer = new byte[255];
baseAddress = BitConverter.ToInt32(btBuffer, 0) + offsetList[offsetList.Length - 1];
ReadProcessMemory( process.Handle, baseAddress, valueBuffer, (uint)valueBuffer.Length, ref lpOutStorage );

Works this without marshall class like Rabirs method

Marshal is only for if your dll is injected. It allows you to directly access the memory without needing 'unsafe' code.

With more offset:
Pointer1 = Ptr + Offset1;
Pointer2 = Pointer1 + Offset2;
Pointer3 = Pointer2 + Offset3;
Money = Pointer3 + MoneyOffset;

Etc...
You can use loops, it makes things easier...
Good luck...

Ah okay thank you
