how can i read input text file using c# ?

Hello Abdalla Ellawad,

Inside program code, there is simple error.

Actual file name of input file is "input.txt" and one used inside program code "input_txt".

Change this and program will work fine. Look at program code line 02. and 04.

// input file Read use StreamUser
if (File.Exists("input_.txt"))
{
StreamReader txtread = new StreamReader("input_.txt");
while (txtread.EndOfStream == false)

I recommend to dispose stream reader or writer after closing one.

Also input file should be in the folder with executable version of program.

All the best,

Željko Peric

PS. This is how Output file looks like after program do whatever it does.
