C# StreamWriter example
Let's see a simple example of StreamWriter class which writes a single line of data into the file.
using System;
using System.IO;
public class StreamWriterExample
{
public static void Main(string[] args)
{
FileStream f = new FileStream("e:\\output.txt", FileMode.Create);
StreamWriter s = new StreamWriter(f);
s.WriteLine("hello c#");
s.Close();
f.Close();
Console.WriteLine("File created successfully...");
}
}
using System.IO;
public class StreamWriterExample
{
public static void Main(string[] args)
{
FileStream f = new FileStream("e:\\output.txt", FileMode.Create);
StreamWriter s = new StreamWriter(f);
s.WriteLine("hello c#");
s.Close();
f.Close();
Console.WriteLine("File created successfully...");
}
}
Output:
File created successfully...
Now open the file, you will see the text "hello c#" in output.txt file.
output.txt:
hello c#
