C# TextWriter Example
- Let's see the simple example of TextWriter class to write two lines data.
using System;
using System.IO;
namespace TextWriterExample
{
class Program
{
static void Main(string[] args)
{
using (TextWriter writer = File.CreateText("e:\\f.txt"))
{
writer.WriteLine("Hello C#");
writer.WriteLine("C# File Handling by wikitechy");
}
Console.WriteLine("Data written successfully...");
}
}
} C# examples - Output :
Data written successfully...f.txt:
Hello C#
C# File Handling by wikitechy
