C# BinaryReader用法

C#BinaryReader类用于从流中读取二进制信息。在System.IO命名空间中找到它。它还支持以特定编码读取字符串。
C#BinaryReader示例
让我们看一下BinaryReader类的简单示例,该类从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()); } } } }

【C# BinaryReader用法】输出:
Double Value : 12.5 String Value : this is string data Boolean Value : true
