.net紧凑框架上的system.io.streamwriter

Question

well i am using all these codes:

// StreamWriter file = new StreamWriter(AppSettings.Instance.Dpath + "\\notaventa.txt");

// StreamWriter file = new StreamWriter(AppSettings.Instance.Dpath + "\\notaventa.txt", false, System.Text.Encoding.GetEncoding(1252));
' Dim objEscritor = New StreamWriter("C:\temp\salida_encoding.txt", True, System.Text.Encoding.Default)
// StreamWriter file = new StreamWriter(AppSettings.Instance.Dpath + "\\notaventa.txt", true, System.Text.Encoding.ASCII);

but none work for print

canción

everyone print

canci?n

how can i fix it? i am using

Answer 1

You can fix it by not specifying Encoding.ASCII . UTF-8 is usually a good bet, although of course it depends on what's going to read the file. Basically ASCII doesn't have any accented characters; it stops at U+007E.

I'd expect Encoding.GetEncoding(1252) to work though, as Windows 1252 contains character "ó". Ditto the default when you don't specify an encoding, as that would use UTF-8. Are you sure your string contains the right data to start with? What are you using to read the file, too?

Answer 2

ASCII does not include support for the ó character. Unless you have compelling reason otherwise, you should always use Unicode:

System.IO.StreamWriter file = new System.IO.StreamWriter(
    Path.Combine(AppSettings.Instance.Dpath, "notaventa.txt"), true, 
    System.Text.Encoding.UTF8);

Unrelated to your question: You should use Path.Combine (rather than explicit string concatenation) for constructing file paths. It would save you the headache of determining whether to include the leading/trailing \\ or not.
