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？ [英] how do i send folder with its contents (subfolder/files) to server-client side?

问题描述

我正在制作文件传输（服务器-客户端）应用程序。即时通讯使用TCP。 （.net 4.0）

I'm making a file transfer (server-client) application. im using TCP. (.net 4.0)

如何将包含所有内容（文件夹/文件）的文件夹发送到另一端？

How do I send a Folder with all its contents(folder/files) to the other side ??

我有以下方法可以正常工作：

I have these methods that works fine:

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

Recieve(string destPath) //recieves a single file

这是Send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;

我也得到：

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

推荐答案

我已经弄清楚答案了

I've figured out the answer

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库。从客户端使用目录的相同名称.. dirName

the server will first create a direcotory .. named the same name of the directory from the client side .. which is dirName

然后它将发送该文件夹中的所有文件..
然后它将递归执行每个文件夹都一样..问题解决了

then it will send all the files in that folder .. then it will recursively do the same for each folder .. problem solved
