For writing small utility programs, C# is pretty good. When it comes to debugging command line utilities you have three alternatives:
- Run it from the command line and use < to redirect input. eg
app < input.txt
- In the debugger add your own command line arguments to the Start options on the property tab. This also lets you specify the
working
directory, ie where it runs. - Wrap it up in this code which redirects the standard input from a text file. it's my preferred solution.
using (StreamReader SR = new StreamReader(@"C:\dev\AboutBot\cs\maps\huge-room.txt")) {
Console.SetIn(SR) ;
string line;
while ((line = SR.ReadLine()) != null)
{
// Do something with line
}
}
The key here is the console.SetIn( method which switches the input to the TextReader device which is part of StreamReader. Wrapping this up in a Using block means that the file is properly closed, and the file handle released when the block is exited.
