我正在制作一个文件传输（服务器-客户端）应用程序。im使用TCP。（.net 4.0）

如何将文件夹及其所有内容（文件夹/文件）发送到另一侧？？

我有这些方法可以很好地工作：

  • Send(string srcPath, string destPath)  //sends a single file


  • Recieve(string destPath) //recieves a single file

    这是发送方法：

    public void Send(string srcPath, string destPath)
{
    using (fs = new FileStream(srcPath, FileMode.Open, FileAccess.Read))
    {
        try
        {
            fileSize = fs.Length;
            while (sum < fileSize)
            {
                if (fileSize - sum < packetSize)
                {
                    count = fs.Read(data, 0, (int)(fileSize - sum));
                    network.Write(data, 0, (int)(fileSize - sum));
                }
                else
                {
                    count = fs.Read(data, 0, data.Length);
                    network.Write(data, 0, data.Length);
                }
                fs.Seek(sum, SeekOrigin.Begin);
                sum += count;
            }
            network.Flush();
        }
        finally
        {
            fs.Dispose();
        }
    }
}

    这就是接收方法：

        public void Recieve(string destPath)
    {
        using (fs = new FileStream(destPath, FileMode.Create, FileAccess.Write))
        {
            try
            {
                while (sum < fileSize)
                {
                    if (fileSize - sum < packetSize)
                    {
                        count = network.Read(data, 0, (int)(fileSize - sum));
                        fs.Write(data, 0, (int)(fileSize - sum));
                    }
                    else
                    {
                        count = network.Read(data, 0, data.Length);
                        fs.Write(data, 0, data.Length);
                    }
                    fs.Seek(sum, SeekOrigin.Begin);
                    sum += count;
                }
            }
            finally
            {
                fs.Dispose();
            }
        }
    }

    这是一个常见的变量：

        const int packetSize = 1024 * 8;    //Packet Size.
    long sum;                           //Sum of sent data.
    long fileSize;                      //File Size.
    int count = 0;                      //data counter.
    static byte[] data = null;          //data buffer.
    NetworkStream network; 
    FileStream fs;

    我还得到了：

    bool IsFolder(string path) //that returns if the path is a folder or a file

    • 如何将文件夹及其内容(子文件夹/文件)发送到服务器客户端

    使用目录路径可以做到这一点：

        public void SendAll(string DirectoryPath)
    {
        if (Directory.Exists(DirectoryPath))
            {
                string[] fileEntries = Directory.GetFiles(DirectoryPath);
                string[] subdirEntries = Directory.GetDirectories(DirectoryPath);
                foreach (string fileName in fileEntries)
                {
                    Send(fileName);

    }
            foreach (string dirName in subdirEntries)
            {
                SendAll(dirName);
            }
        }

    }

    我已经找到了答案

    public void SendFolder(string srcPath, string destPath)
    {
        string dirName = Path.Combine(destPath, Path.GetFileName(srcPath));
        CreateDirectory(dirName);  // consider that this method creates a directory at the server
        string[] fileEntries = Directory.GetFiles(srcPath);
        string[] subDirEntries = Directory.GetDirectories(srcPath);
        foreach (string filePath in fileEntries)
        {
            Send(srcPath, dirName);
        }
        foreach (string dirPath in subDirEntries)
        {
            SendFolder(dirPath, dirName);
        }
    }

    服务器将首先创建一个目录。。从客户端命名了与目录相同的名称。。哪个是dirName

    然后它将发送该文件夹中的所有文件。。那么它将递归地对每个文件夹执行相同的操作。。问题已解决
