Question

我正在尝试解压缩一个字节数组并使用二进制读取器将其转换为字符串。当执行以下代码时，inStream位置从0更改为数组的长度，但str始终为空字符串。

BinaryReader br = null;
string str = String.Empty;

using (MemoryStream inStream = new MemoryStream(pByteArray))
{
    GZipStream zipStream = new GZipStream(inStream, CompressionMode.Decompress);
    BinaryReader br = new BinaryReader(zipStream);
    str = br.ReadString();
    inStream.Close();
    br.Close();
}

您还没有展示如何压缩数据，但这里是压缩和解压缩缓冲区的完整示例：

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

class Program
{
    static void Main()
    {
        var test = "foo bar baz";

        var compressed = Compress(Encoding.UTF8.GetBytes(test));
        var decompressed = Decompress(compressed);
        Console.WriteLine(Encoding.UTF8.GetString(decompressed));
    }

    static byte[] Compress(byte[] data)
    {
        using (var compressedStream = new MemoryStream())
        using (var zipStream = new GZipStream(compressedStream, CompressionMode.Compress))
        {
            zipStream.Write(data, 0, data.Length);
            zipStream.Close();
            return compressedStream.ToArray();
        }
    }

    static byte[] Decompress(byte[] data)
    {
        using (var compressedStream = new MemoryStream(data))
        using (var zipStream = new GZipStream(compressedStream, CompressionMode.Decompress))
        using (var resultStream = new MemoryStream())
        {
            zipStream.CopyTo(resultStream);
            return resultStream.ToArray();
        }
    }
}

通过BinaryReader将字节数组解压缩为字符串，产生空字符串
