SampleBytes.Length >= currentPos + 1it should be:
SampleBytes.Length > currentPos + 1One my example on how to detect the encoding/codepage of a text file using TextFileEncodingDetector project in .NET core. First to mention that not even Notepad++ can't detect the encoding/codepage of a text file correctly. Try to save one file with, for example, Windows-1252 character set and reopen it again.
In my case I will save few files with different encoding in C#. In order to test if files were correctly saved I have opened them with binary editor in Visual studio 2019: File -> Open Open with Binary editor Check hexadecimal value of unicode code points for example UTF-16 Table, UTF-8 Table, or for example "ß" - German eszett, here or here. And here is da code:
using KlerksSoft; using System; using System.Collections.Generic; using System.Diagnostics; using System.IO; using System.Text; namespace EncodingDetector { class Program { static void Main(string[] args) { Console.WriteLine("Read all encodings from the system and write file for each encoding."); string exampleStringToWrite = "üöäß;ÜÖÄß@€µ"; List<string> savedFiles = new List<string>(); ProcessModule processModule = Process.GetCurrentProcess().MainModule; string exePath = string.Empty; if (processModule != null) { exePath = Path.GetDirectoryName(processModule.FileName); } foreach (EncodingInfo encodingInfo in Encoding.GetEncodings()) { string fileName = $"{encodingInfo.DisplayName}.txt"; foreach (char c in Path.GetInvalidFileNameChars()) { fileName = fileName.Replace(c, '_'); } fileName = Path.Combine(exePath ?? string.Empty, fileName); using (StreamWriter sw = new StreamWriter(File.Open(fileName, FileMode.Create), encodingInfo.GetEncoding())) { sw.WriteLine(exampleStringToWrite); savedFiles.Add(fileName); Console.WriteLine($"File {fileName} saved."); } } string windows1252File = Path.Combine(exePath ?? string.Empty, "windows1252.txt"); Encoding.RegisterProvider(CodePagesEncodingProvider.Instance); using (StreamWriter sw = new StreamWriter(File.Open(windows1252File, FileMode.Create), Encoding.GetEncoding(1252))) { sw.WriteLine(exampleStringToWrite); Console.WriteLine($"File {windows1252File} saved."); } Console.WriteLine("Press any key to detect encodings"); Console.ReadKey(); foreach (string savedFile in savedFiles) { DisplayEncodingInConsole(savedFile); } DisplayEncodingInConsole(windows1252File); Console.WriteLine("Finished"); Console.ReadKey(); } private static void DisplayEncodingInConsole(string fileName) { Encoding encoding = TextFileEncodingDetector.DetectTextFileEncoding(fileName); if (encoding is null) { Console.WriteLine($"File {fileName} is most probably encoded as {Encoding.Default}"); } else { Console.WriteLine($"File {fileName} encoded as {encoding}"); } } } }Here is the source code.
