c# - Writing to .bin binary file -


i trying write integer numbers binary file, keeps giving weird characters in binary file. example, try write 2000, in file strange. how fix it? couldn't find solution anywhere.

i use following code:

 //create file         filestream fs = new filestream("iram.bin", filemode.create);         // create writer data.         binarywriter w = new binarywriter(fs);  w.write((int) 2000);  w.close(); fs.close();

i think problem not reading data properly.

you need read data using binaryreader so...

    using (filestream fs2 = new filestream("iram.bin", filemode.open))     {         using(binaryreader r = new binaryreader(fs2))         {             var integervalue = r.readint32();         }     }

unless of course want write text file in case don't want binarywriter write data out.

if want write out text data this... (be sure set encoding need)

    using (var tw = new streamwriter("iram.txt", true, encoding.ascii))     {         tw.writeline(2000);     }

edit: jesse mentioned want wrap disposable objects in using blocks.

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
