C#使用自带类库实现压缩文件、解压文件

网上有很多压缩和解压的第三方类库，下面代码是使用C#自带类库实现的文件压缩解压。

注意在用c#自带的类库实现文件压缩和解压的时候需要添加下面的引用：
using System.IO;

using System.IO.Compression;

System.IO.Compression.FileSystem;

自己封装的帮助类：

 

    public class ZipHelper
    {
        /// 

        /// 压缩单文件
        /// 
        /// 文件路径

        /// 是否保存原文件
        public static void CompressSingleFile(string filePath, string savePath, bool isReserved = true)
        {
            if (!File.Exists(filePath))
            {
                throw new FileNotFoundException($"{filePath}不存在.");
            }
            FileInfo file = new FileInfo(filePath);
            string filename = Path.GetFileNameWithoutExtension(filePath);
            string tempDir = Path.Combine(file.DirectoryName, "temp_Zip");
            if (!File.Exists(tempDir))
            {

            }

调用方式：

        static void Main(string[] args)
        {
            string[] arr = new string[3] { @"D:\Projects\Test\Data\1.txt", @"D:\Projects\Test\Data\2.txt", @"D:\Projects\Test\Data\3.txt" };
            ZipHelper.CompressSingleFile(@"D:\Projects\Test\Data\1.txt", @"D:\Projects\Test\Data\1.zip", false);
            ZipHelper.CompressSingleDir(@"D:\Projects\Test\Data", @"D:\Projects\Test\Data.zip");
            ZipHelper.CompressMultiFile(arr, @"D:\Projects\Test\Data.zip",false);
            ZipHelper.DeCompressMulti(@"D:\Projects\Test", @"D:\Projects\Test\Data.zip");
        }
