How to write out a text file in C# with a code page other than utf-8?

Question

I want to write out a text file.

Instead of the default UTF-8, I want to write it encoded as ISO-8859-1 which is code page 28591. I have no idea how to do this...

I'm writing out my file with the following very simple code:

using (StreamWriter sw = File.CreateText(myfilename))
{

    sw.WriteLine("my text...");
    sw.Close();
}

?

Thanks!

Answer 1

Change the Encoding of the stream writer. It's a property.

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

So:

sw.Encoding = Encoding.GetEncoding(28591);

Prior to writing to the stream.

Answer 2

using System.IO;
using System.Text;

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

An alternate way of getting your encoding:

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...");    
}

Check out the docs for the StreamWriter constructor.

Simple!

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