The BinaryWriter class in C# is employed for composing binary data into a stream. This class is located within the System.IO namespace and provides functionality for encoding and writing strings into the stream with a specified encoding format.
C# BinaryWriter Example
Let's explore a basic illustration of the BinaryWriter class that is responsible for storing data in a .dat file.
Example
using System;
using System.IO;
namespace BinaryWriterExample
{
class Program
{
static void Main(string[] args)
{
string fileName = "e:\\binaryfile.dat";
using (BinaryWriter writer = new BinaryWriter(File.Open(fileName, FileMode.Create)))
{
writer.Write(2.5);
writer.Write("this is string data");
writer.Write(true);
}
Console.WriteLine("Data written successfully...");
}
}
}
Output:
Output
Data written successfully...
