C# Sharp Exercises: Create a file and write an array of strings
C# Sharp File Handling: Exercise-6 with Solution
Write a program in C# Sharp to create a file and write an array of strings to the file.
Sample Solution:-
C# Sharp Code:
using System;
using System.IO;
class WriteTextFile
{
static void Main()
{
string fileName = @"mytest.txt";
string[] ArrLines ;
int n,i;
Console.Write("\n\n Create a file and write an array of strings :\n");
Console.Write("---------------------------------------------------\n");
if (File.Exists(fileName))
{
File.Delete(fileName);
}
Console.Write(" Input number of lines to write in the file :");
n= Convert.ToInt32(Console.ReadLine());
ArrLines=new string[n];
Console.Write(" Input {0} strings below :\n",n);
for(i=0;i<n;i++)
{
Console.Write(" Input line {0} : ",i+1);
ArrLines[i] = Console.ReadLine();
}
System.IO.File.WriteAllLines(fileName, ArrLines);
using (StreamReader sr = File.OpenText(fileName))
{
string s = "";
Console.Write("\n The content of the file is :\n",n);
Console.Write("----------------------------------\n");
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(" {0} ",s);
}
Console.WriteLine();
}
}
}
Sample Output:
Create a file and write an array of strings : --------------------------------------------------- Input number of lines to write in the file :2 Input 2 strings below : Input line 1 : This is a 1st line Input line 2 : This is a 2nd line The content of the file is : ---------------------------------- This is a 1st line This is a 2nd line
