如何使用C#下载并解压缩gzip文件？

Install-Package System.IO.Compression.Zip

using System;
using System.IO;
using System.IO.Compression;
using System.Net;

namespace GZipDownloadAndExtract
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "http://example.com/file.gz"; // 替换为您要下载的gzip文件的URL
            string outputPath = "output.txt"; // 替换为您要保存的解压缩文件的路径

            DownloadAndExtractGZip(url, outputPath);
        }

        static void DownloadAndExtractGZip(string url, string outputPath)
        {
            using (var client = new WebClient())
            {
                client.DownloadFile(url, "file.gz");
            }

            using (var input = File.OpenRead("file.gz"))
            using (var output = File.Create(outputPath))
            using (var gzip = new GZipStream(input, CompressionMode.Decompress))
            {
                gzip.CopyTo(output);
            }

            File.Delete("file.gz");
        }
    }
}
