ICSharpCode.SharpZipLib.Zip.FastZip 不压缩文件名中含有特殊字符的文件

发布于 2024-10-03 22:30:42 字数 118 浏览 0 评论 0原文

我正在使用 ICSharpCode.SharpZipLib.Zip.FastZip 来压缩文件，但我遇到了一个问题：

当我尝试压缩文件名中包含特殊字符的文件时，它不起作用。当文件名中没有特殊字符时它起作用。

我认为你不能使用 FastZip。您需要迭代这些文件并添加自己指定的条目：

entry.IsUnicodeText = true;

告诉 SharpZipLib 该条目是 unicode。

string[] filenames = Directory.GetFiles(sTargetFolderPath);

// Zip up the files - From SharpZipLib Demo Code
using (ZipOutputStream s = new
    ZipOutputStream(File.Create("MyZipFile.zip")))
{
    s.SetLevel(9); // 0-9, 9 being the highest compression

    byte[] buffer = new byte[4096];

    foreach (string file in filenames)
    {
         ZipEntry entry = new ZipEntry(Path.GetFileName(file));

         entry.DateTime = DateTime.Now;
         entry.IsUnicodeText = true;
         s.PutNextEntry(entry);

         using (FileStream fs = File.OpenRead(file))
         {
             int sourceBytes;
             do
             {
                 sourceBytes = fs.Read(buffer, 0, buffer.Length);

                 s.Write(buffer, 0, sourceBytes);

             } while (sourceBytes > 0);
         }
    }
    s.Finish();
    s.Close();
 }

I think you cannot use FastZip. You need to iterate the files and add the entries yourself specifying:

entry.IsUnicodeText = true;

To tell SharpZipLib the entry is unicode.

string[] filenames = Directory.GetFiles(sTargetFolderPath);

// Zip up the files - From SharpZipLib Demo Code
using (ZipOutputStream s = new
    ZipOutputStream(File.Create("MyZipFile.zip")))
{
    s.SetLevel(9); // 0-9, 9 being the highest compression

    byte[] buffer = new byte[4096];

    foreach (string file in filenames)
    {
         ZipEntry entry = new ZipEntry(Path.GetFileName(file));

         entry.DateTime = DateTime.Now;
         entry.IsUnicodeText = true;
         s.PutNextEntry(entry);

         using (FileStream fs = File.OpenRead(file))
         {
             int sourceBytes;
             do
             {
                 sourceBytes = fs.Read(buffer, 0, buffer.Length);

                 s.Write(buffer, 0, sourceBytes);

             } while (sourceBytes > 0);
         }
    }
    s.Finish();
    s.Close();
 }

如果您愿意，您可以继续使用 FastZip，但您需要为其提供一个 ZipEntryFactory，以使用 IsUnicodeText = true 创建 ZipEntry。。

var zfe = new ZipEntryFactory { IsUnicodeText = true };
var fz = new FastZip { EntryFactory = zfe };
fz.CreateZip("out.zip", "C:\in", true, null);

You can continue using FastZip if you would like, but you need to give it a ZipEntryFactory that creates ZipEntrys with IsUnicodeText = true.

var zfe = new ZipEntryFactory { IsUnicodeText = true };
var fz = new FastZip { EntryFactory = zfe };
fz.CreateZip("out.zip", "C:\in", true, null);

您必须下载并编译最新版本的 SharpZipLib 库，以便您可以使用

entry.IsUnicodeText = true;

这里的代码片段（稍作修改）：

FileInfo file = new FileInfo("input.ext");
using(var sw = new FileStream("output.zip", FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
    using(var zipStream = new ZipOutputStream(sw))
    {
        var entry = new ZipEntry(file.Name);
        entry.IsUnicodeText = true;
        zipStream.PutNextEntry(entry);

        using (var reader = new FileStream(file.FullName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            while ((bytesRead = reader.Read(buffer, 0, buffer.Length)) > 0)
            {
                byte[] actual = new byte[bytesRead];
                Buffer.BlockCopy(buffer, 0, actual, 0, bytesRead);
                zipStream.Write(actual, 0, actual.Length);
            }
        }
    }
}

You have to download and compile the latest version of SharpZipLib library so you can use

entry.IsUnicodeText = true;

here is your snippet (slightly modified):

FileInfo file = new FileInfo("input.ext");
using(var sw = new FileStream("output.zip", FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
    using(var zipStream = new ZipOutputStream(sw))
    {
        var entry = new ZipEntry(file.Name);
        entry.IsUnicodeText = true;
        zipStream.PutNextEntry(entry);

        using (var reader = new FileStream(file.FullName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            while ((bytesRead = reader.Read(buffer, 0, buffer.Length)) > 0)
            {
                byte[] actual = new byte[bytesRead];
                Buffer.BlockCopy(buffer, 0, actual, 0, bytesRead);
                zipStream.Write(actual, 0, actual.Length);
            }
        }
    }
}
