C# Program to read all the lines one by one in a file
Use ReadAllLines() method to read all the lines one by one in a file.
Let’s say we have a file “new.txt” with the following lines.
One Two Three
Firstly, set the path of the file to be read.
String myPath = "new.txt";
Now add it under a string array to fetch the lines on by one.
String[] fLine = File.ReadAllLines(myPath);
Let’s say you need to fetch the first line. For that.
fLine[0]
The following is the complete example that reads lines one by one in a file.
Example
using System;
using System.IO;
public class Demo {
public static void Main() {
String myPath = "new.txt";
String[] fLine;
// array of lines in a file
fLine = File.ReadAllLines(myPath);
// read lines of a file
Console.WriteLine("Line 1: "+fLine[0]);
Console.WriteLine("Line 2: "+fLine[1]);
Console.WriteLine("Line 3: "+fLine[2]);
Console.WriteLine("Line 4 "+fLine[3]);
}
}Output
Line1: One Line2: Two Line3: Three Line4: Four
