C# StreamWriter for writing file

In c#, you can write the text to a file using the StreamWriter class.

Example- 

Here is a simple example to demonstrates the StreamWriter in c# for writing the text to the file,

using System;
using System.IO;
class Program
{
   static void Main()
   {
       // Specify the file path
       string filePath = "Sample.txt";
       // Create a StreamWriter instance to write in the file
       using (StreamWriter writer = new StreamWriter(filePath))
       {
           // Write text to the file
           writer.WriteLine("Hello, world!");
           writer.WriteLine("This is a test.");
           writer.WriteLine("Writing sample text to a file using C# StreamWriter class.");
       }
       Console.WriteLine("Text has been written to the file.");
       Console.ReadLine();
   }
}

In the above example-

• We specify the file path where we want to write the text (sample.txt).
• We create a StreamWriter instance named writer and pass the file path to its constructor.
• We use the WriteLine method of the StreamWriter instance to write text to the file.
• The transaction ensures that the StreamWriter is properly disposed of after use, which locks the file and frees any associated objects.
