using System; using System.IO; class Program { static void Main(string[] args) { using (BinaryReader reader = new BinaryReader(File.Open("file.bin", FileMode.Open))) { char nextChar = reader.PeekChar(); Console.WriteLine("Next char: " + nextChar); } } }
using System; using System.IO; class Program { static void Main(string[] args) { using (BinaryReader reader = new BinaryReader(File.Open("file.bin", FileMode.Open))) { while (reader.PeekChar() != -1) { char nextChar = reader.ReadChar(); Console.WriteLine("Read char: " + nextChar); } } } }Here, the code uses `PeekChar` in a loop to read each character in the file until the end of the stream is reached. Overall, `PeekChar` is a useful method for checking the next available character in a binary data stream without moving the position of the stream. This method is located in the `System.IO` package library.
