C#-Lösung zum Lesen verstümmelter chinesischer Dateien

FileStream aFile = new FileStream(SingleFile, FileMode.Open);
StreamReader sr = new StreamReader(aFile, Encoding.GetEncoding("gb2312"), true);
string FileContent = sr.ReadToEnd();
aFile.Close();
ProcessData Pd = new ProcessData();
Pd.ProceData(FileContent);

StreamReader verwendet 3 Parameter. Die meisten Chinesen sind gb2312. Wenn es nicht utf-8 ist, verwenden Sie gb2312.


Das System verfügt über eine utf-Erkennung , siehe Wie folgt
