如何使用SharpCompress的BZip2Stream压缩字符串？ [英] How to use SharpCompress' BZip2Stream to compress a string?

问题描述

我正在尝试使用SharpCompress的BZip2Stream压缩字符串（str），但是无法实现。以下是我到目前为止的代码，

I am trying to compress a string (str) using SharpCompress' BZip2Stream but unable to achieve it. Following is the code I have so far,

public static string Compress(string str)
{
    var data = Encoding.UTF8.GetBytes(str);
    using (MemoryStream stream = new MemoryStream())
    {
        using (BZip2Stream zip = new BZip2Stream(stream, SharpCompress.Compressor.CompressionMode.Compress))
        {
            zip.Write(data, 0, data.Length);
            var compressed = Encoding.UTF8.GetString(stream.ToArray());
            return compressed;
        }
    }
}

无论我通过什么字符串到 str 总是返回 BZh 。

No matter what string i pass to str it always returns BZh.

推荐答案

我相信您需要完成/关闭/刷新bzip2流，以确保所有压缩数据在从存储流中读取数据之前，将数据写入存储流。尝试：

I believe you need to finalize/close/flush the bzip2 stream in order to make sure all compressed data is written to the memory stream prior to reading data from the memory stream. Try:

using (MemoryMemoryStream stream = new MemoryStream())
{
    using (BZip2Stream zip = new BZip2Stream(stream, SharpCompress.Compressor.CompressionMode.Compress))
    {
        zip.Write(data, 0, data.Length);
        zip.Close();
    }
    var compressed = Encoding.UTF8.GetString(stream.ToArray());
    return compressed;
}
