Given multiple lines and we have to write all lines into a text file.
File.WriteAllLines()
This is a method of "File class, which is used to write all lines in a text file.
Syntax:
void WriteAllLines(string filename);
Parameter(s):
- filename - name of the file.
Program
using System;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
string[] line={
"Sample Line 1",
"Sample Line 2",
"Sample Line 3",
"Sample Line 4",
"Sample Line 5"
};
File.WriteAllLines("sample.txt", line);
Console.WriteLine("Data written successfully");
}
}
}

Note: In above program, we need to remember, when we use "File" class, System.IO namespace must be included in the program.
