How to get CMD/console encoding in C#

问题:

I need to specify the correct codepage to pack the files with zip library. As I see, I need to specify console encoding (866 in my case).

 C:\Users\User>mode

 Status for device CON:
 ----------------------
     Lines:          300
     Columns:        130
     Keyboard rate:  31
     Keyboard delay: 1
     Code page:      866 <- I need to get this value in C# code

Console.OutputEncoding returns 1251, which is not what I need.

Thanks,

Alex

Update 1: Obviously, execute "mode" in cmd.exe and parse output should work but it seems too rude. I'm looking for .NET solution.

Update 2: The application is windows forms application, not a console app.

回答1:

The default code page for a console mode app is determined by the system locale. Control Panel + Region and Language, Administrative tab, Change System Locale. Your Windows code page is Cyrillic, so is your console code page so there's a reasonable chance that this code will work:

        int lcid = GetSystemDefaultLCID();
        var ci = System.Globalization.CultureInfo.GetCultureInfo(lcid);
        var page = ci.TextInfo.OEMCodePage;
        // etc..

    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    public static extern int GetSystemDefaultLCID();

Do avoid writing code like this, 8-bit text encodings are a mine field. There certainly isn't any decent reason to have to run a console-mode zip program, there are plenty of .NET zip libraries available.

回答2:

You need Encoding.CodePage property:

var codePage = Console.OutputEncoding.CodePage;

which will give you a code page value (866 in your example).
