如何使用UTF-8以外的代碼頁在C＃中寫出文本文件？

Question

我想寫出一個文本文件。

而不是默認的UTF-8，我想寫它編碼為ISO-8859-1，這是代碼頁28591.我不知道如何做到這一點......

我用以下非常簡單的代碼寫出我的文件：

using (StreamWriter sw = File.CreateText(myfilename))
{
    sw.WriteLine("my text...");
    sw.Close();
}

Answer 1

using System.IO;
using System.Text;

using (StreamWriter sw = new StreamWriter(File.Open(myfilename, FileMode.Create), Encoding.WhateverYouWant))
{    
    sw.WriteLine("my text...");     
}

獲取編碼的另一種方法：

using System.IO;
using System.Text;

using (var sw  = new StreamWriter(File.Open(@"c:\myfile.txt", FileMode.CreateNew), Encoding.GetEncoding("iso-8859-1"))) {
    sw.WriteLine("my text...");             
}

查看StreamWriter構造函數的文檔。

Answer 2

簡單！

System.IO.File.WriteAllText(path, text, Encoding.GetEncoding(28591));

Answer 3

用FileStream包裝StreamWriter，這樣：

string fileName = "test.txt";
string textToAdd = "Example text in file";
Encoding encoding = Encoding.GetEncoding("ISO-8859-1"); //Or any other Encoding

using (FileStream fs = new FileStream(fileName, FileMode.CreateNew))
{
    using (StreamWriter writer = new StreamWriter(fs, encoding))
    {
        writer.Write(textToAdd);
    }
}

你可以有這樣的東西

 switch (EncodingFormat.Trim().ToLower())
    {
        case "utf-8":
            File.WriteAllBytes(fileName, ASCIIEncoding.Convert(ASCIIEncoding.ASCII, new UTF8Encoding(false), convertToCSV(result, fileName)));
            break;
        case "utf-8+bom":
            File.WriteAllBytes(fileName, ASCIIEncoding.Convert(ASCIIEncoding.ASCII, new UTF8Encoding(true), convertToCSV(result, fileName)));
            break;
        case "ISO-8859-1":
            File.WriteAllBytes(fileName, ASCIIEncoding.Convert(ASCIIEncoding.ASCII, Encoding.GetEncoding("iso-8859-1"), convertToCSV(result, fileName)));
            break;
        case ..............
    }

更改流編寫器的編碼。 這是一個屬性。

http://msdn.microsoft.com/en-us/library/system.io.streamwriter.encoding.aspx

所以：

sw.Encoding = Encoding.GetEncoding(28591);

在寫入流之前。
