我想访问和编辑文本文件从c#应用程序是在网络上,并通过ip地址访问。访问文件不需要凭据,所以我想要一些示例代码或指南,如何开始实现此任务。我想编辑的文件是在安卓平板电脑和Android应用程序(SD卡)的存储,我通过ip地址访问,因为我的机器和安卓设备在同一网络上。由于

  try
        {
        StreamReader sr = new StreamReader("192.168.1.2/NewFolder/TickerText.txt");
            //Read the first line of text
            line = sr.ReadLine();
            //Continue to read until you reach end of file
            while (line != null) 
            {
                //write the lie to console window
                textBox1.Text=line;
                //Read the next line
                line = sr.ReadLine();
            }
            //close the file
            sr.Close();
            Console.ReadLine();
        }
        catch(Exception ae)
        {
            textBox1.Text = ae.Message;
        }

编辑文本文件驻留在网络(局域网)

假设两台计算机都是windows,您可以共享文件所在的文件夹,并使用以下命令访问该文件夹:

using (StreamWriter writer = new StreamWriter(@"''IPADDRESS'directories'file.txt") 
{
    writer.Write("Word ");
}

和阅读:

File.ReadAllLines(@"''IPADDRESS'directories'file.txt");

与其他文件读取/写入器相同。


由于文件所在的android操作系统的附加信息,以及FTP的包含,我只能说

  • simple-ftp-get-file
  • net-ftpwebrequest
  • FtpWebRequest <—defiant
  • c# ftp项目

将对你有用。

我将粘贴来自CodeProject文章的相关信息。这些代码都不是我的,但是它会做你需要的。
只要记得在你完成后将文件上传到android系统。

/* Download File */
    public void download(string remoteFile, string localFile)
    {
        try
        {
            /* Create an FTP Request */
            ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + "/" + remoteFile);
            /* Log in to the FTP Server with the User Name and Password Provided */
            ftpRequest.Credentials = new NetworkCredential(user, pass);
            /* When in doubt, use these options */
            ftpRequest.UseBinary = true;
            ftpRequest.UsePassive = true;
            ftpRequest.KeepAlive = true;
            /* Specify the Type of FTP Request */
            ftpRequest.Method = WebRequestMethods.Ftp.DownloadFile;
            /* Establish Return Communication with the FTP Server */
            ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
            /* Get the FTP Server's Response Stream */
            ftpStream = ftpResponse.GetResponseStream();
            /* Open a File Stream to Write the Downloaded File */
            FileStream localFileStream = new FileStream(localFile, FileMode.Create);
            /* Buffer for the Downloaded Data */
            byte[] byteBuffer = new byte[bufferSize];
            int bytesRead = ftpStream.Read(byteBuffer, 0, bufferSize);
            /* Download the File by Writing the Buffered Data Until the Transfer is Complete */
            try
            {
                while (bytesRead > 0)
                {
                    localFileStream.Write(byteBuffer, 0, bytesRead);
                    bytesRead = ftpStream.Read(byteBuffer, 0, bufferSize);
                }
            }
            catch (Exception ex) { Console.WriteLine(ex.ToString()); }
            /* Resource Cleanup */
            localFileStream.Close();
            ftpStream.Close();
            ftpResponse.Close();
            ftpRequest = null;
        }
        catch (Exception ex) { Console.WriteLine(ex.ToString()); }
        return;
    }

你可以这样读一个文件:

File.ReadAllLines(@"''192.168.1.1'FileName.txt");

会返回一个string[],或者像这样:

foreach (string line in File.ReadLines(@"''192.168.1.1'FileName.txt"))
{
    ...
}

一行接一行。您可以像这样添加到文件(例如,添加新行):

File.AppendAllText(@"''192.168.1.1'FileName.txt", "Hello, World!");

还有很多其他的方法。利用System.Io命名空间
