c++ code translation to c# : Randomizer

Question

Hi all I would like to translate the following c++ code lines to c# : uint32 v; int max_array = SCREEN_WIDTH * SCREEN_HEIGHT; v = (int)(max_array * (rand()/RAND_MAX+1.0))); all ideas are welcome. thanks a lot in advance. br alex

thanks to all for your replies. my problem was actually that the RAND_MAX variable. In C++ this is a predefined constant located in the file. br alex

It's practicly the same in C# :) Only uint32 should be translated to uint and the rand() function is going to be the object Random.Next(); I suppose SCREEN_WIDTH  SCREEN_HEIGHT and RAND_MAX are #define d? So this should be some static variable in the class. Something like this: class CPLUSPLUS { static int SCREEN_WIDTH = 640; static int SCREEN_HEIGHT = 480; static int RAND_MAX = 100; public static int SomeFunction() { ////////////////////////////////// //Translate ////////////////////////////////// uint v; int max_array = SCREEN_WIDTH * SCREEN_HEIGHT; Random rand = new Random(); v = (uint)(max_array * ( rand.NextDouble() / RAND_MAX+1.0 )); ////////////////////////////////// //End Translate ////////////////////////////////// return (int)v; } public static void Main() { Console.WriteLine(CPLUSPLUS.SomeFunction()); Console.ReadLine(); } }

try this: Int32 v; int max_array = SCREEN_WIDTH * SCREEN_HEIGHT; Random randomizer = new Random(); v = (int)(max_array * randomizer.Next(RAND_MAX) + 1);

What kind of app? (Winformconsole...) If you use Visual studio you wont need our help. It is self programable. Just look how to use the Random method probably under math namespace. check the properties of the window you are using for the screen size.
