How to read existing text files without defining path

Question

Most of the examples shows how to read text file from exact location (f.e. \"C:\\Users\\Owner\\Documents\\test1.txt\"). But, how to read text files without writing full path

Answer 1

As your project is a console project you can pass the path to the text files that you want to read via the string[] args

static void Main(string[] args)
{
}

Within Main you can check if arguments are passed

if (args.Length == 0){ System.Console.WriteLine("Please enter a parameter");}

Extract an argument

string fileToRead = args[0];

Nearly all languages support the concept of argument passing and follow similar patterns to C#.
