MemoryX

The memory library for .NET applications helps you access Windows APIs such as WriteProcessMemory or ReadProcessMemory in the simplest way.

⚠️ This project is no longer active and maintained. Feel free to use code inside or forks and add new functionality to meet your needs.

Motivation

I created this library to help me read-write memory from any process, and game (at that time it's Warcraft III). I copied the code and started the new project over and over again. So I decided to learn how to create a library and plug it into my game helper.

Functions

** Sometimes you might need to run an executable as administrator to access other process's memory.

OpenProcess using process name, this will select the first process name that we've found.

    MemoryX.Memory MemX = new MemoryX.Memory();
    MemX.GetProcessHandle("notepad");

OpenProcess using PID.

    MemoryX.Memory MemX = new MemoryX.Memory();
    MemX.GetProcessHandle(12345);

Get BadAddress of a module

    public long GetBaseAddress(String moduleName)

Example

    var procName = "Tutorial-x86_64"; 
    long baseAddress = myProc.GetBaseAddress(procName + ".exe");
    Console.WriteLine("BaseAddress: {0}", (baseAddress).ToString("X")); // BaseAddress: 100000000

Write Process Memory

    WriteMemory( [address], [data types])

Write integer into selected address

    WriteMemory( address, 12345);

Write string into selected address

    WriteMemory( address, "Hello");

Write float value into selected address

    WriteMemory(address, 3.1415928f);

Write double value into selected address

    WriteMemory(address, 7.1474d);

Write a single byte value into address

    WriteMemory(address, 0xba);

Write an array of bytes into address

    WriteMemory(address, new byte[] { 0xaa, 0xbb, 0xcc });

---

Read Process Memory

Read one byte

    Console.WriteLine("BYTES IS "  + myProc.ReadMemory(address , 1)[0].ToString("X"));

Read int16 from memory using BitConverter

byte[] b = myProc.ReadMemory(address, 2);
Console.WriteLine(BitConverter.ToInt16(b, 0));

---

For others example use:

    // New an object , one object per process
    MemoryX.Memory myProc = new MemoryX.Memory();
    
    // for process name without .exe 
    // Example you open task manager and see "notepad.exe" 
    // you can change and put it into "procName" without extensions
    var procName = "notepad"; 
    
    //address for access our process memory
    var address = 0x000D1940;

    // for open our process
    myProc.GetProcessHandle(procName);

    // for write memory string value to memory
    myProc.WriteMemory(address, "Hello");

    // for write memory int value to memory
    myProc.WriteMemory(address, 12345);

    // for write memory float or single value to memory
    myProc.WriteMemory(address, 3.1415928f);

    // for write memory double value to memory
    myProc.WriteMemory(address, 7.1474d);

    // for write memory byte value to memory
    myProc.WriteMemory(address, 0xba);

    // for write memory array of bytes value to memory
    myProc.WriteMemory(address, new byte[] { 0xaa, 0xbb, 0xcc });
    
    // for read a single byte value from memory
    Console.WriteLine("BYTES IS "  + myProc.ReadMemory(address , 1)[0].ToString("X"));

    byte[] arrBytes = myProc.ReadMemory(address, 5);
    // for print byte values
    foreach (byte b in arrBytes)
        Console.WriteLine(b.ToString("X"));
    
    // for read a memory address value and return to double
    Console.WriteLine(myProc.ReadDouble(address));

    // for read a memory address value and return to flot or Single
    Console.WriteLine(myProc.ReadFloat(address));

    // for read memory and return to string value
    Console.WriteLine(myProc.ReadString(address, 11));


    // get a base address of module and print out
    Console.WriteLine(myProc.GetBaseAddress("notepad.exe").ToString("X"));

Read memory pointer

    MemoryX.Memory myProc = new MemoryX.Memory();
    var procName = "Tutorial-x86_64";
    myProc.GetProcessHandle(procName);
    
    long baseAddress = myProc.GetBaseAddress(procName + ".exe"); 
    long address = baseAddress + 0x002C4A80; 
    int[] offsets = new int[] {0x10, 0x18 ,0 , 0x18}; 
 
    Console.WriteLine(myProc.ReadMemoryPointerInt(address, offsets)); 

Write memory int to address

    MemoryX.Memory myProc = new MemoryX.Memory();
    String procName = "Tutorial-x86_64";
    myProc.GetProcessHandle(procName);

    long baseAddress = myProc.GetBaseAddress(procName + ".exe");
    long address = baseAddress + 0x002C4A00;
    int[] offsets = new int[] { 0x598, 0x6F0, 0xD8, 0xA0, 0x780 };

    Console.WriteLine(myProc.WriteMemoryPointer(address, offsets, 666));
