非常感谢您的支持。我正在尝试复制一个 zip 文件夹并从指定的路径创建文件夹位置到另一个路径，然后解压缩该文件夹。
创建部分工作正常我可以将zip从指定位置创建到新的指定位置，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，但我不确定在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，但似乎没有答案或工作。我相信有更简单的方法来做到这一点（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
// ****Updated 15/02/21 with replace statement***:

using System.IO.Compression;

{

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

System.IO.Directory.CreateDirectory(pathString);
ZipFile.ExtractToDirectory(pathInput, pathString);
}

{
Console.WriteLine("File \"{0}\" already exists.", fileName);
return;
}
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
}
****\\ 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使用的 .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] 以检查该错误，您可以转到该链接。
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，但在您的代码中，您提供了一个扩展名为 .zip 的文件位置。它必须是一个文件夹。 我做了一些更改检查这个。
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();
}
}
}
