C# BinaryReader
C# BinaryReader class is used to read binary information from stream. It is found in System.IO namespace. It also supports reading string in specific encoding.
C# BinaryReader Example
Let's see the simple example of BinaryReader class which reads data from dat file.
using System;
using System.IO;
namespace BinaryWriterExample
{
class Program
{
static void Main(string[] args)
{
WriteBinaryFile();
ReadBinaryFile();
Console.ReadKey();
}
static void WriteBinaryFile()
{
using (BinaryWriter writer = new BinaryWriter(File.Open("e:\\binaryfile.dat", FileMode.Create)))
{
writer.Write(12.5);
writer.Write("this is string data");
writer.Write(true);
}
}
static void ReadBinaryFile()
{
using (BinaryReader reader = new BinaryReader(File.Open("e:\\binaryfile.dat", FileMode.Open)))
{
Console.WriteLine("Double Value : " + reader.ReadDouble());
Console.WriteLine("String Value : " + reader.ReadString());
Console.WriteLine("Boolean Value : " + reader.ReadBoolean());
}
}
}
}
using System.IO;
namespace BinaryWriterExample
{
class Program
{
static void Main(string[] args)
{
WriteBinaryFile();
ReadBinaryFile();
Console.ReadKey();
}
static void WriteBinaryFile()
{
using (BinaryWriter writer = new BinaryWriter(File.Open("e:\\binaryfile.dat", FileMode.Create)))
{
writer.Write(12.5);
writer.Write("this is string data");
writer.Write(true);
}
}
static void ReadBinaryFile()
{
using (BinaryReader reader = new BinaryReader(File.Open("e:\\binaryfile.dat", FileMode.Open)))
{
Console.WriteLine("Double Value : " + reader.ReadDouble());
Console.WriteLine("String Value : " + reader.ReadString());
Console.WriteLine("Boolean Value : " + reader.ReadBoolean());
}
}
}
}
Output:
Double Value : 12.5
String Value : this is string data
Boolean Value : true
String Value : this is string data
Boolean Value : true
