Read random line from text file to text box in C# [closed]

Answer 1

This will return a random line from a file:

private static Random _rand = new Random();    

public static string GetRandomLine(string filename)
{
    var lines = File.ReadAllLines(filename);

    var lineNumber = _rand.Next(0, lines.Length);

    return lines[lineNumber];
}

Answer 2

To display a random line from a text file, you should:

• First load all the lines of text into an array (each item in the array should be a line of text from the file).
• Then you want to generate a random number between 0 and the number of lines in the text. Use the Random class for that.
• And finally you want to print the line in the array using the generated random number.

Here's the pseudo-code to do the same thing:

Load TextFile
string[] text = Array of lines of text in TextFile
Random rnd = new Random object
int randomLine = New random number generated between 0 and (text.Length - 1)
Print text[randomLine]
