What is the use of BufferedStream in file handling?

Question

ICSM Computer · Answer

BufferedStream in C# is used to improve performance during file I/O by adding a
buffer between the stream and the file. It reduces the number of direct disk access operations by
temporarily storing data in memory.
Why use BufferedStream?
Minimizes expensive disk I/O operations by batching small reads/writes into fewer large ones.Improves performance especially when you're performing many small read/write operations.Useful when wrapping slower streams like FileStream.
Typical Use Case
using System;
using System.IO;
class Program
{
    static void Main()
    {
        string path = "largefile.dat";
        using (FileStream fileStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite))
        using (BufferedStream bufferedStream = new BufferedStream(fileStream))
        {
            byte[] data = System.Text.Encoding.UTF8.GetBytes("Buffered I/O Example");
            bufferedStream.Write(data, 0, data.Length);
            // You must flush to ensure data is written to the file
            bufferedStream.Flush();
        }
    }
}
Key Points
BufferedStream doesn't replace FileStream—it wraps it.It’s most useful when doing frequent, small reads/writes.Remember to call Flush() or close the stream to ensure data is written.
