ZipStorer没有创造Android的C＃中的任何文件 [英] ZipStorer not creating any file in Android c#

问题描述

你好我使用Xamarin用C＃，使一个应用程序，可以压缩和解压缩文件，所以试了几次后，我发现zipStorer。

Hi i am using Xamarin with c# to make an app that can zip and unzip files so after a few tries i found zipStorer.

HTTP：//zipstorer.$c$cplex.com/

下面是我的code

 ZipStorer zip = ZipStorer.Open(Convert.ToString(Android.OS.Environment.GetExternalStoragePublicDirectory("BrSatisfacao/aaa.zip")), FileAccess.Read);

                List<ZipStorer.ZipFileEntry> dir = zip.ReadCentralDir();

                string path;

                foreach (ZipStorer.ZipFileEntry entry in dir)

                {

                    if (Path.GetFileName(entry.FilenameInZip) == "08.jpg")

                    {

                        path = Path.Combine(Convert.ToString(Android.OS.Environment.GetExternalStoragePublicDirectory("BrSatisfacao/")), Path.GetFileName(entry.FilenameInZip));

                        zip.ExtractFile(entry, Convert.ToString(Android.OS.Environment.GetExternalStoragePublicDirectory("BrSatisfacao/sample.jpg")));

                        break;

                    }   

                }

                zip.Close();

在几个小时code运行良好并打开拉链，并显示所有在控制台中，但正在创建无拉链...难道我做错了什么？

After a couple of hours the code is running fine and opening the zip and showing all in the console but no zip is being created... am i doing something wrong?

推荐答案

在内部ZipStorer使用的字符集437做（在ZipStorer.cs线85）的编码和编码取消：

Internally ZipStorer uses the character set 437 to do the encoding and un-encoding (line 85 in ZipStorer.cs):

    private static Encoding DefaultEncoding = Encoding.GetEncoding(437);

当你建立你的应用程序

Xamarin不包含该字符的默认设置。正如本地化明确和国际化文档：

Xamarin does not include this character set by default when you build your application. As stated in the Localisation And Internationalisation document:

的为了减少应用程序的大小，Xamarin.iOS不包括任何特定的编码，你需要指导的mTouch包括包含您需要的编码支持的组件。的

要包含的字符集，添加西字符，通过在应用程序中设置的国际化设置：

To include the character set, add the West character set through the internationalisation settings in your application:

确保你检查这两个调试和发布

我不能得到这个工作对我来说，当我添加ZIP支持我的申请。最后，我通过使用Java IO库，但有可能是可添加的跨平台支持ZIP组件推出我自己的ZIP支持。

I could not get this to work for me when I was adding zip support to my application. In the end I rolled my own zip support by using the Java IO libraries but there may be a component available to add cross platform zip support.
