c# - 如何使用太长/重复的路径处理解压缩 ZipFile

Question

在 Windows 中解压缩文件时，我偶尔会遇到路径问题

1. 对于 Windows 来说太长了(但在创建该文件的原始操作系统中没问题)。
2. 由于不区分大小写而“重复”

使用 DotNetZip，ZipFile.Read(path)每当读取具有这些问题之一的 zip 文件时，调用就会出错。这意味着我什至无法尝试过滤掉它。

using (ZipFile zip = ZipFile.Read(path))
{
    ...
}

处理读取这类文件的最佳方法是什么？

示例 zip 来自这里: https://github.com/MonoReports/MonoReports/zipball/master

这里是关于异常的更多细节:

Ionic.Zip.ZipException: Cannot read that as a ZipFile
---> System.ArgumentException: An > item with the same key has already been added.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.Collections.Generic.Dictionary2.Insert(TKey key, TValue value, Boolean add)<br/>
at System.Collections.Generic.Dictionary2.Add(TKey key, TValue value)
at Ionic.Zip.ZipFile.ReadCentralDirectory(ZipFile zf)
at Ionic.Zip.ZipFile.ReadIntoInstance(ZipFile zf)

解决方案:

根据@Cheeso 的建议，我可以从流中读取所有内容，避免重复和路径问题:

//using (ZipFile zip = ZipFile.Read(path))
using (ZipInputStream stream = new ZipInputStream(path))
{
    ZipEntry e;
    while( (e = stream.GetNextEntry()) != null )
    //foreach( ZipEntry e in zip)
    {
        if (e.FileName.ToLower().EndsWith(".cs") ||
            e.FileName.ToLower().EndsWith(".xaml"))
        {
            //var ms = new MemoryStream();
            //e.Extract(ms);
            var sr = new StreamReader(stream);
            {
                //ms.Position = 0;
                CodeFiles.Add(new CodeFile() { Content = sr.ReadToEnd(), FileName = e.FileName });
            }
        }
    }
}

对于PathTooLongException的问题，我发现你不能使用DotNetZip .相反，我所做的是调用 command-line version of 7-zip ;这创造了奇迹。

public static void Extract(string zipPath, string extractPath)
{
    try
    {
        ProcessStartInfo processStartInfo = new ProcessStartInfo
        {
            WindowStyle = ProcessWindowStyle.Hidden,
            FileName = Path.GetFullPath(@"7za.exe"),
            Arguments = "x \"" + zipPath + "\" -o\"" + extractPath + "\""
        };
        Process process = Process.Start(processStartInfo);
        process.WaitForExit();
        if (process.ExitCode != 0) 
        {
            Console.WriteLine("Error extracting {0}.", extractPath);
        }
    }
    catch (Exception e)
    {
        Console.WriteLine("Error extracting {0}: {1}", extractPath, e.Message);
        throw;
    }
}
