C# BinaryReader
C# BinaryReader 类用于从流中读取二进制信息。它位于 System.IO 命名空间中。也支持读取特定编码的字符串。
C#BinaryReader Example
我们来看BinaryReader类的简单例子，它从dat文件中读取数据。
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());
}
}
}
}
输出:
double Value : 12.5
String Value : this is string data
Boolean Value : true
