❔ Converting String to an integer with a Hexadecimal Value

Hello Folks, I got a process with a prefered imagebase equal to 002E0000. I would like to store that value assigned to an integer since its a hexadecimal value which can be stored as it. What is more I would like the value to be have a prefix "0x" so in full format the integer should look like this

C#
public static int PROCESSBASEADRESS_INT = 0x002E0000

C#
public static int PROCESSBASEADRESS_INT = 0x002E0000

I have a following code that gets the value from process and saves it as an integer however here is my issues: - it does not store it in hexadecimal value - I need it stored as an hexadecimal integer value with pre-fix "0x"

C#

            Process process = Process.GetProcessesByName(testprocess)[0];
            ProcessModule mainModule = process.MainModule;
            int baseAddressInt = int.Parse(mainModule.BaseAddress.ToString("X"), NumberStyles.HexNumber);
            PROCESSBASEADRESS_INT = baseAddressInt;
            Console.WriteLine(PROCESSBASEADRESS_INT);

C#

            Process process = Process.GetProcessesByName(testprocess)[0];
            ProcessModule mainModule = process.MainModule;
            int baseAddressInt = int.Parse(mainModule.BaseAddress.ToString("X"), NumberStyles.HexNumber);
            PROCESSBASEADRESS_INT = baseAddressInt;
            Console.WriteLine(PROCESSBASEADRESS_INT);

It prints it out as a INT32 value. I need to print out hexadecimal value with a prefix "0x" I tried converting it to string and adding "0x" but after that I cant convert it back to hexadecimal integer that represent exactly what string was showing.

its converting string to hex-string. I need hex-int. for an example

C#

   public static int BaseAddress = 0x2B58DF0;

C#

   public static int BaseAddress = 0x2B58DF0;

Checking it out. Since a lot of these answers where posted back in 2015 the languaged developed and I guess we dont have to use such a complicated method anymore.

C#      

// GETTING THE BASE ADDRESS OF A PROCESS
            Process process = Process.GetProcessesByName(testprocess)[0];
            ProcessModule mainModule = process.MainModule;
            string hexBaseAddress = mainModule.BaseAddress.ToString("X");
            int baseAddress = int.Parse(hexBaseAddress, System.Globalization.NumberStyles.HexNumber);
            Console.WriteLine(hexBaseAddress);
            Console.WriteLine(baseAddress);

C#      

// GETTING THE BASE ADDRESS OF A PROCESS
            Process process = Process.GetProcessesByName(testprocess)[0];
            ProcessModule mainModule = process.MainModule;
            string hexBaseAddress = mainModule.BaseAddress.ToString("X");
            int baseAddress = int.Parse(hexBaseAddress, System.Globalization.NumberStyles.HexNumber);
            Console.WriteLine(hexBaseAddress);
            Console.WriteLine(baseAddress);

First print, prints out correctly - still without prefix but its not a big issue. I can solve it later. Second print, after conversion to int it prints out still INT32 number.

They are the same thing, theres no hex int Passing 32 is the same as 0x20 to a function. its seen no differently

No such thing as a "hexadecimal integer" An integer is an integer Ah, it's already been mentioned I see
