放气管柱C#

我试图对从websocket连接获得的字符串进行放气，但每次尝试运行此代码时都会出现错误。我还尝试使用ascii编码直接从字符串中获取字节，但也不起作用

public static byte[] Decompress(string input)
{

    byte[] data = Convert.FromBase64String(input)
    byte[] decompressedArray = null;

    using (MemoryStream decompressedStream = new MemoryStream())
    {
        using (MemoryStream compressStream = new MemoryStream(data))
        {
            using (DeflateStream deflateStream = new DeflateStream(compressStream, CompressionMode.Decompress))
            {
                deflateStream.CopyTo(decompressedStream);
            }
        }
        decompressedArray = decompressedStream.ToArray();
    }
    return decompressedArray;
}

System.IO.InvalidDataException:“块长度与其补码不匹配。”

我尝试了这段代码的一些不同的变体，但没有任何效果，但我知道这是可能的，因为我可以使用这个网站和deflate选项对其进行放气

我要放气的一个示例字符串：

字符串（JSON）可能来自一个字符串。
您可以使用另一个流来解压缩数据内容：

► 您需要.Net Framework 4.7.2+才能正确解压缩数据

值得注意的是，压缩格式有点不合适。压缩数据签名，

78:01

，可能表明这是一个ZLib压缩字符串，因此基于ZLib（来自.Net Framework 4.5）的.Net应该解压缩数据。
7-Zip和WinZip都无法打开数据（保存为二进制文件的流）

JSON是UTF8编码的（它也适用于ASCII字符串）：

如果我在你的例子中使用GzipStream，我仍然会在System.IO.InvalidDataException中得到一个错误：“GZip头中的幻数不正确。请确保你正在传递GZip流。”结果表明它只适用于.NET Framework 4.7.2，而我使用的是4.6.1，我更改了它，现在它可以工作了，谢谢你说得对。您至少需要

4.7.2

<代码>4.7.1在此也失败。我会把它加到笔记上。

using System.IO;
using System.IO.Compression;
using System.Text;

public static byte[] Decompress(string input)
{
    byte[] data = Convert.FromBase64String(input)

    using (var decompressedStream = new MemoryStream())
    using (var compressStream = new MemoryStream(data))
    using (var gzip = new GZipStream(compressStream, CompressionMode.Decompress)) {
        gzip.CopyTo(decompressedStream);
        return decompressedStream.ToArray();
    }
}

string json = Encoding.UTF8.GetString(Decompress(base64String));
