讀/寫無法識別.txt文件C＃中的字符/

Question

當我想從txt文件中讀取/寫入這些字符時出現問題。

我嘗試使用FileStream，在兩種情況下，我都將其編碼為這些字符（ßÚ¾·²µ µ÷）

TxtFileModelInfo modelInfo = new TxtFileModelInfo();
TxtExporter export = new TxtExporter(modelInfo);
try
{                
    using (var outstream = new FileStream(fileName, FileMode.Create))
    {
        foreach (var obj in objects)
        {
            export.ExportObject(obj, outstream);
        }
    }                
}

TxtFileModelInfo modelInfo = new TxtFileModelInfo();
TxtImporter importer = new TxtImporter(modelInfo);
try
{                                               
    using (var instream = new FileStream(fileName,FileMode.Open))
    {                
      List<ApplicationObject> objects = importer.ImportFromStream(instream);
      if (objects != null && objects.Count > 0)
      {
          return objects;
      }
      else
      {
          Console.WriteLine(@"Object could not be readed from file {0}", 
          fileName);
      }                
  }                

}

如果有人有一些建議，我將不勝感激。

FileStream僅讀取或寫入原始類型（如字節數組），您將需要StreamReader和StreamWiter才能使用任何編碼。

例如，讀取數據時，您將像這樣使用它：

using(var instream  = new FileStream(filename,FileMode.Open)) {
    using(var sr = new StreamReader(instream, System.Text.Encoding.UTF8)) {
        //do your work here
    }
}

寫入文件是相同的，除了使用StreamWriter ：

using(var outstream = new FileStream(filename,FileMode.Create)) {
    using(var sw = new StreamWriter(outstream, System.Text.Encoding.UTF8)) {
        //do your work here
    }
}
