Question

I have a Console application (C#) that interacts with the User, and every step is shown via Console.Writeline.

Now I wanted to write these events to XML or TXT, and my only guess was to create a List and add all the Console.Writelines to it, but then I noticed that logging the Console.Readline is mandatory, and that’s the reason I’m asking this question.

How do I log Console.Reads/Console.Writes to a TXT/XML?

Thank you.

The simplest way to accomplish this is to use File.AppendAllText

Opens a file, appends the specified string to the file, and then closes the file. If the file does not exist, this method creates a file, writes the specified string to the file, then closes the file.

Something like this

string line = Console.ReadLine();
Console.WriteLine(line); // I gather you want to write it out again?
File.AppendAllText(@"C:\SomePath\MyFile.txt", line);

If you would prefer to gather all of the text first and then write it all out when your program exits, you could do something like this:

List<string> inputLines = new List<string>();

// Loop here getting lines
string line = Console.ReadLine();
inputLines.Add(line);

// When done:
File.WriteAllLines(@"C:\SomePath\MyFile.txt", inputLines.ToArray());
