将创建的 zip 文件夹解压缩到同一文件夹？

Question

非常感谢您的支持。我正在尝试复制一个 zip 文件夹并从指定路径创建文件夹位置，然后将其解压缩到另一个路径。

创建部分工作正常我可以从指定位置创建 zip 到新的指定位置，但是当我解压缩它时，它告诉我该文件夹正在使用中。这是有道理的，但我不确定创建后是否有另一种解压缩方式。我检查了其他问题和方法，但似乎都没有答案或工作。我相信有更简单的方法可以做到这一点（下面的代码）：

using System;
using System.IO.Compression;

namespace ZipWorker
{
    public class FolderCreate
    {
        static void Main()
        {
            string pathInput;
            string pathString;

            // Define creation location for update files. Loop continuously until path is entered.
            do
            {
                Console.WriteLine("Please enter the path for the creation of the Folder");
                pathString = Console.ReadLine();
                pathString = pathString.Replace("\"", "");

            } while (String.IsNullOrEmpty(pathString));

            // Define location of upgrade zip file to copy. Loop continuously until path is entered. 
            do
            {
                Console.WriteLine("Please enter the path for the Folder to copy");
                pathInput = Console.ReadLine();
                pathInput = pathInput.Replace("\"", "");

            } while (String.IsNullOrEmpty(pathInput));

            // Create the folder path. You can verify in File Explorer that you have this e.g.
            // structure in the C: drive.
            //    Local Disk (C:)
            //        Top-Level Folder
            //            SubFolder
            System.IO.Directory.CreateDirectory(pathString);

            // Create a file name for the upgrade zip file you want to create.Based off user console input.
            string fileName = System.IO.Path.GetFileName(pathInput);
            // This example uses an string for the name. You can specify any file in the console.

            // Combine to add the upgrade file name to the path.
            pathString = System.IO.Path.Combine(pathString, fileName);

            // Verify the path that you have constructed.
            Console.WriteLine("Path to my file: {0}\n", pathString);

            // Check that the file doesn't already exist. If it doesn't exist, create
            // DANGER: System.IO.File.Create will overwrite the file if it already exists.
            // This could happen even with random file names, although it is unlikely.
            if (!System.IO.File.Exists(pathString))
            {
                System.IO.File.Create(pathString);
                ZipFile.ExtractToDirectory(pathString,pathString);

            }
            else
            {
                Console.WriteLine("File \"{0}\" already exists.", fileName);
                return;
            }
            // Keep the console window open in debug mode.
            System.Console.WriteLine("Press any key to exit.");
            System.Console.ReadKey();
        }
    }
}
    // Sample output:

// Path to my file: c:\Top-Level Folder\SubFolder\ttxvauxe.vv0

            // Creates a file path and removes .zip from folder name, for the upgrade zip file you want to install. Based off user console input. 
            string fileName = System.IO.Path.GetFileName(pathInput);
            if (fileName.Contains(".zip"))
            {
                fileName = fileName.Replace(".zip", "");
            }
            // This example uses an release string for the name. You can specify any file in the console.

            // Combine to add the upgrade file name to the path.

****\\ I've spotted the error I was referencing the same variable in my if statement

if (pathString.Contains("\"") || pathInput.Contains("\""))
            {
                pathString = pathString.Replace("\"", "");
                pathInput = pathString.Replace("\"", "");
            }

\\ This should have been pathInput = pathInput sorted now.

如果您的文件是应该可以工作的 .zip 文件。我在一个 rar 文件中尝试了这个，它给了我错误 [System.IO.Invalid Data Exception] 来检查那个错误，你可以去那个链接。

End of Central Directory record could not be found

您正在尝试将文件（.zip 扩展名）解压缩到文件夹。这就是我从您的问题中了解到的，但是在您的代码中，您提供了一个具有 .zip 扩展名的文件位置。它必须是一个文件夹。 我做了一些更改，检查一下。

namespace ZipWorker
{
    class Program
    {
        static void Main()
        {
            string pathInput;
            string pathString;

            
            do
            {
                Console.WriteLine("Please enter the path for the folder that you want to create");
                pathString = Console.ReadLine();

            } while (String.IsNullOrEmpty(pathString));

            
            do
            {
                Console.WriteLine("Please enter the path for the Folder to copy");
                pathInput = Console.ReadLine();

            } while (String.IsNullOrEmpty(pathInput));

            
            System.IO.Directory.CreateDirectory(pathString);

            
            string fileName = System.IO.Path.GetFileName(pathInput);
            if (fileName.Contains(".zip"))
            {
                fileName = fileName.Replace(".zip", "");
            }
            
            pathString = System.IO.Path.Combine(pathString, fileName) ;

            
            Console.WriteLine("Path to my file: {0}\n", pathString);
            
            if (!System.IO.Directory.Exists(pathString))
            {
                System.IO.Directory.CreateDirectory(pathString);
                ZipFile.ExtractToDirectory(pathInput, pathString);

            }
            else
            {
                Console.WriteLine("File \"{0}\" already exists.", fileName);
                return;
            }
            System.Console.WriteLine("Press any key to exit.");
            System.Console.ReadKey();
        }
    }
}
