C# StreamReader for Reading file
In C#, reading a file using the StreamReader class is simple.
Example-and 
Here is a simple example to read data from text file using StreamReader class in C#,
using System;
using System.IO;
class Program
{
   static void Main()
   {
       // Specify the file path
       string filePath = "sample.txt";
       // Check if the file exists in the location
       if (File.Exists(filePath))
       {
           // Creating a StreamReader instance to read from the file
           using (StreamReader reader = new StreamReader(filePath))
           {
               // Read the file line by line
               string line;
               while ((line = reader.ReadLine()) != null)
               {
                   // Print each line to the console
                   Console.WriteLine(line);
               }
           }
       }
       else
       {
           Console.WriteLine("File not found: " + filePath);
       }
       Console.ReadLine();
   }
}
In the above example-
Specifies the file path of the file we want to read (sample.txt).We use File.Exists(filePath) to check if the file exists.If the file exists, we create a StreamReader instance named 
reader and pass the file path to its constructor.We use a while loop to read a file line using the ReadLine() method of the
StreamReader instance.In the loop, we print each line to the console.The transaction ensures that the StreamReader is properly disposed of after use, which locks the file and frees any associated objects.
and 
Output-and 
Hello, world!
This is a test.
