Like freopen and scanf in c#

Question

Who knows the freopen and scanf function functionality but in c# not in c???????

thanks

Answer 1

Filestream and Streamreader.

Answer 2

freopen does not have a direct parallel. You'd have to Close and then re-create a FileStream object to get similar behavior.

scanf and similar type-unsafe functions have been replaced with Parse methods, e.g., int.Parse. Your stdin stream is Console.In. You'll have to do your own delimiting from the input stream into a string, which can then be parsed into an integer.

Answer 3

I doit like this, as you say:

StreamReader objReader = new StreamReader("input.txt");

String readed = "";

while(readed != null){
    readed = objReader.ReadLine();  
    System.out.println(readed);
}

using StreamReader then I can split it with ' ' to take each variable (in c will be scanf("%d%d%d",&v1,&v2,&v3))
