.NET [C#]Reading text files, Creating text files, Storing in an array

[Serkiee]

I'm making a console application that reads from a text file, stores its contents into an array and then randomly chooses a name to win.

I need to have it read names from a .txt file line by line using streamreader and store the names into an array. I also need to check if the file doesn't exists. if it doesn't it needs to create a new .txt file and write the names that the user enters into the file.

I know how to read a file line by line but I don't know how to store each line into an array. I also know how to enter names and store it into an array but I don't know how to make a text file from an array.

If it doesn't make sense I can try explain it more.

Finally this is how it needs to be set out:

if (File.Exists(PATH))

{

​

}​

else

{

​

}

You can always use an ArrayList and then convert that to an Array.
Edit: here's some code I found from searching:

//Code Source: http://www.dotnetperls.com/streamreader
List<string> list = new List<string>();
	using (StreamReader reader = new StreamReader("file.txt"))
	{
	    string line;
	    while ((line = reader.ReadLine()) != null)
	    {
		list.Add(line); // Add to list.
		Console.WriteLine(line); // Write to console.
	    }
	}

You want to do something like this:

if ( file does not exist ), ask user for input, create new file input.txt
Read file. Each line, add to string array. Reach end of file.
Create a random integer between 0 and the size of the string array minus 1.
Print out the element of the array at the position of the random integer.

You can always do something with string.Split(<CHAR>);

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

foreach(string Name in new StreamReader("text.txt").ReadToEnd().Split('\n').ToString())
         Applicants.Add(Name);

return Applicants[new Random().Next(0, Applicants.Count() - 1);

You still need help, PM me.

I've already finished it but thanks anyway
