修改函数来读取float C＃ [英] modify function to read float C#

问题描述

  [DllImport（kernel32.dll）] 
 public静态外部布尔ReadProcessMemory（IntPtr hProcess，int lpBaseAddress，字节[]缓冲区，int大小，int lpNumberOfBytesRead）; 
 
 
 $ b public static int ReadAddress（string Process_Name，string Address_Offsets）
 {
 Process [] P; （（P = Process.GetProcessesByName（Process_Name））长度== 0）返回-1; 
 if 
 int Addy = -1; 
 while（Address_Offsets.Contains（））
 Address_Offsets = Address_Offsets.Replace（，）; 
 
 int Index = -1; （（Index = Address_Offsets.IndexOf（0x，StringComparison.OrdinalIgnoreCase））！= -1）
 Address_Offsets = Address_Offsets.Replace（Address_Offsets.Substring（Index，2），）; 
 
 string [] tmp = Address_Offsets.Split（''）; 
 if（tmp [0] .Contains（+））
 {
 string [] AD = tmp [0] .Split（'+'）; 
 foreach（P [0] .Modules中的ProcessModule M）
 if（M.ModuleName.ToLower（）== AD [0] .ToLower（））
 Addy = M.BaseAddress。 ToInt32（）+ int.Parse（AD [1]，NumberStyles.HexNumber）; 
} 
 else Addy = int.Parse（tmp [0]，NumberStyles.HexNumber）; 
 
 if（tmp.Length == 1）return Addy; 
 byte [] buff = new byte [4]; 
 ReadProcessMemory（P [0] .Handle，Addy，buff，4,0）; 
 Addy = BitConverter.ToInt32（buff，0）; 
 for（int i = 1; i< tmp.Length; i ++）
 {
 int Off = int.Parse（tmp [i]，NumberStyles.HexNumber）; 
 ReadProcessMemory（P [0] .Handle，Addy + Off，buff，4,0）; 
 Addy = i！=（tmp.Length  -  1）？ BitConverter.ToInt32（buff，0）：Addy + = Off; 
} 
 return Addy; 
 
 $ / code $ / pre 
 
我是这样使用的：
 
 
  ReadAddress（solitaire，solitaire.exe + 97074 2c 10）; 
  
这个函数适用于读取整数。但我想读花车。 
有人告诉我，我必须做
 $ b $ pre $ ReadmecessMemory（P [0] .Handle，Addy，buff， 4，0）; //解除引用所有指针后，获得最终的期望值。 
 Addy = BitConverter.ToSingle（buff，0）; // ToSingle将值转换为float。 
  

但是我不明白在函数中把他的代码放在哪里。有人可以帮我吗？
thx提前：D。

解决方案

  int dataRead = ReadAddress solitaire，solitaire.exe + 97074 2c 10）; 
  

给你（希望）在 int int 之后，你需要把它转换为float，这意味着 / p>

  byte [] bytesOfTheNumber = BitConverter.GetBytes（dataRead）; 
  

首先将整数转换为一个字节数组，然后

  float theFloatYouWant = BitConverter.ToSingle（bytesOfTheNumber，0）; 
  

使用该字节数组获取 float 。

I found this function on the internet:

[DllImport("kernel32.dll")]
public static extern bool ReadProcessMemory(IntPtr hProcess, int lpBaseAddress, byte[] buffer, int size, int lpNumberOfBytesRead);



    public static int ReadAddress(string Process_Name, string Address_Offsets)
    {
        Process[] P;
        if ((P = Process.GetProcessesByName(Process_Name)).Length == 0) return -1;
        int Addy = -1;
        while (Address_Offsets.Contains("  "))
            Address_Offsets = Address_Offsets.Replace("  ", " ");

        int Index = -1;
        while ((Index = Address_Offsets.IndexOf("0x", StringComparison.OrdinalIgnoreCase)) != -1)
            Address_Offsets = Address_Offsets.Replace(Address_Offsets.Substring(Index, 2), "");

        string[] tmp = Address_Offsets.Split(' ');
        if (tmp[0].Contains("+"))
        {
            string[] AD = tmp[0].Split('+');
            foreach (ProcessModule M in P[0].Modules)
                if (M.ModuleName.ToLower() == AD[0].ToLower())
                    Addy = M.BaseAddress.ToInt32() + int.Parse(AD[1], NumberStyles.HexNumber);
        }
        else Addy = int.Parse(tmp[0], NumberStyles.HexNumber);

        if (tmp.Length == 1) return Addy;
        byte[] buff = new byte[4];
        ReadProcessMemory(P[0].Handle, Addy, buff, 4, 0);
        Addy = BitConverter.ToInt32(buff, 0);
        for (int i = 1; i < tmp.Length; i++)
        {
            int Off = int.Parse(tmp[i], NumberStyles.HexNumber);
            ReadProcessMemory(P[0].Handle, Addy + Off, buff, 4, 0);
            Addy = i != (tmp.Length - 1) ? BitConverter.ToInt32(buff, 0) : Addy += Off;
        }
        return Addy;
    }

I is used like:

ReadAddress("solitaire", "solitaire.exe+97074 2c 10");

This function works good for reading integers. But I want to read floats. Someone told me, that I have to do

ReadProcessMemory(P[0].Handle, Addy, buff, 4, 0); // after you dereference all pointers and get the final "desired" value. 
Addy = BitConverter.ToSingle(buff, 0); // ToSingle converts value to float.

But I do not understand where to put his suggested code in the function. Can someone help me pls? thx in advance :D.

解决方案

int dataRead = ReadAddress("solitaire", "solitaire.exe+97074 2c 10");

Gives you (hopefully) 4 bytes in an int.

After you've read this int, you need to convert it to float, which means

byte[] bytesOfTheNumber = BitConverter.GetBytes(dataRead);

converting the integer number into a byte array first, and then

float theFloatYouWant = BitConverter.ToSingle(bytesOfTheNumber, 0);

using that byte array for getting a float.
