c# - 无法正确加载底层压缩例程

Question

我不能再在我的 UWP 应用程序中使用 System.IO.Compression 库，我需要它来压缩未压缩过大以适合独立存储的字符串。我怀疑这是在我更新所有 Nuget 包时开始的。我不断收到以下错误，代码如下，

EDIT 这似乎只发生在 DEBUG 模式下。当我在 RELEASE 模式下编译我的应用程序并部署到设备或本地机器时，它可以在两者上运行。但是当我尝试调试时，它崩溃了(崩溃发生在稍后的代码中，该代码尝试使用解压缩的字符串，该字符串不包含任何内容，因为压缩/解压缩静默失败 - 在 using 语句中 - 并且我的应用程序中的其余代码已执行)

The underlying compression routine could not be loaded correctly.

堆栈跟踪

at System.IO.Compression.Deflater.DeflateInit(CompressionLevel compressionLevel, Int32 windowBits, Int32 memLevel, CompressionStrategy strategy) at System.IO.Compression.Deflater..ctor(CompressionLevel compressionLevel, Int32 windowBits) at System.IO.Compression.DeflateStream.InitializeDeflater(Stream stream, Boolean leaveOpen, Int32 windowBits, CompressionLevel compressionLevel) at System.IO.Compression.DeflateStream..ctor(Stream stream, CompressionMode mode, Boolean leaveOpen, Int32 windowBits) at System.IO.Compression.DeflateStream..ctor(Stream stream, CompressionMode mode, Boolean leaveOpen) at myApp.Utilities.Extensions.Compress(String uncompressedString) at myApp.ExtendedSplash.d__17.MoveNext()

我想这可能与此有关

Unzipping throws an "The underlying compression routine could not be loaded correctly"

我不知道该怎么办。是否有不依赖于 System.IO 的替代 Zip 库，我可以在 UWP 中使用？ - 我尝试安装 DotNetZip，但无法安装。

代码

public static class Extensions
{
    /// <summary>
    /// Compresses a string and returns a deflate compressed, Base64 encoded string.
    /// </summary>
    /// <param name="uncompressedString">String to compress</param>
    public static string Compress(this string uncompressedString)
    {
        var compressedStream = new MemoryStream();
        var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString));

        using (var compressorStream = new DeflateStream(compressedStream, CompressionMode.Compress, true))
        {
            uncompressedStream.CopyTo(compressorStream);
        }

        return Convert.ToBase64String(compressedStream.ToArray());
    }

    /// <summary>
    /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
    /// </summary>
    /// <param name="compressedString">String to decompress.</param>
    public static string Decompress(this string compressedString)
    {
        var decompressedStream = new MemoryStream();
        var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

        using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
        {
            decompressorStream.CopyTo(decompressedStream);
        }

        return Encoding.UTF8.GetString(decompressedStream.ToArray());
    }
}

clrcompression.dll 文件很可能已损坏。清理并构建或重建解决方案。
