C# 复制本地文件夹粘贴到共享文件夹

你可以使用C#中的System.IO和System.Net命名空间来实现复制本地文件夹到共享文件夹的功能。以下是实现的基本步骤：

1. 使用Directory.GetFiles和Directory.GetDirectories方法获取本地文件夹中的文件和子文件夹。

2. 使用File.Copy方法将文件从本地文件夹复制到共享文件夹。

3. 使用Directory.CreateDirectory方法在共享文件夹中创建子文件夹。

4. 递归调用自己，将子文件夹中的文件和文件夹复制到共享文件夹中。

以下是一个示例代码，可以将本地文件夹D:\LocalFolder复制到共享文件夹\\Server\SharedFolder：

using System.IO;
using System.Net;

public void CopyFolderToSharedFolder()
{
    string localFolderPath = @"D:\LocalFolder";
    string sharedFolderPath = @"\\Server\SharedFolder";

    // Create a WebRequest instance for the shared folder
    WebRequest sharedFolderRequest = WebRequest.Create(sharedFolderPath);
    NetworkCredential credentials = new NetworkCredential("username", "password");
    sharedFolderRequest.Credentials = credentials;

    // Get the response from the shared folder request
    WebResponse sharedFolderResponse = sharedFolderRequest.GetResponse();

    // Get the shared folder stream and create a StreamWriter instance
    Stream sharedFolderStream = sharedFolderResponse.GetResponseStream();
    StreamWriter sharedFolderWriter = new StreamWriter(sharedFolderStream);

    // Get the files and directories in the local folder
    string[] files = Directory.GetFiles(localFolderPath);
    string[] directories = Directory.GetDirectories(localFolderPath);

    // Copy the files to the shared folder
    foreach (string file in files)
    {
        // Get the filename from the file path
        string filename = Path.GetFileName(file);

        // Create the shared file path
        string sharedFilePath = Path.Combine(sharedFolderPath, filename);

        // Copy the file to the shared folder
        File.Copy(file, sharedFilePath);
    }

    // Copy the directories to the shared folder
    foreach (string directory in directories)
    {
        // Get the directory name from the directory path
        string directoryName = Path.GetFileName(directory);

        // Create the shared directory path
        string sharedDirectoryPath = Path.Combine(sharedFolderPath, directoryName);

        // Create the shared directory
        Directory.CreateDirectory(sharedDirectoryPath);

        // Recursively copy the files and directories in the local directory to the shared directory
        CopyFolder(directory, sharedDirectoryPath);
    }

    // Close the shared folder stream and response
    sharedFolderWriter.Close();
    sharedFolderResponse.Close();
}

private void CopyFolder(string sourceFolderPath, string targetFolderPath)
{
    // Get the files and directories in the source folder
    string[] files = Directory.GetFiles(sourceFolderPath);
    string[] directories = Directory.GetDirectories(sourceFolderPath);

    // Copy the files to the target folder
    foreach (string file in files)
    {
        // Get the filename from the file path
        string filename = Path.GetFileName(file);

        // Create the target file path
        string targetFilePath = Path.Combine(targetFolderPath, filename);

        // Copy the file to the target folder
        File.Copy(file, targetFilePath);
    }

    // Copy the directories to the target folder
    foreach (string directory in directories)
    {
        // Get the directory name from the directory path
        string directoryName = Path.GetFileName(directory);

        // Create the target directory path
        string targetDirectoryPath = Path.Combine(targetFolderPath, directoryName);

        // Create the target directory
        Directory.CreateDirectory(targetDirectoryPath);

        // Recursively copy the files and directories in the source directory to the target directory
        CopyFolder(directory, targetDirectoryPath);
    }
}

在上面的代码中，我们首先使用WebRequest和NetworkCredential类设置访问共享文件夹所需的凭据。然后，我们使用Directory.GetFiles和Directory.GetDirectories方法获取本地文件夹中的文件和子文件夹，并使用File.Copy方法将文件从本地文件夹复制到共享文件夹。接下来，我们使用Directory.CreateDirectory方法在共享文件夹中创建子文件夹，并递归调用自己，将子文件夹中的文件和文件夹复制到共享文件夹中。最后，我们关闭共享文件夹流和响应。
