Please be advised that I am a beginner in C#.

I am writing a remote administrator tool that is sending CMD controls to the client and returning results to the server.

In this example, when I view the returned data in Debug.Console, it is in two rows as in the below image.

But what I see in the txtBox is all concatenated...

How do I split the text by rows in the txtBox as in the imported data?

This is how I populate the txtBox in the server side:

if (strdata.StartsWith("2"))
                    {
                        updateText(txtCmdConsole, strdata);
                    }


private void updateText(TextBox text, string strdata)
        {
            text.Invoke((MethodInvoker)delegate
            {
                text.AppendText(strdata.Substring(2));
            });

        }

Here is the Cmd output handler:

private void CmdOutputDataHandler(object sendingProcess, DataReceivedEventArgs outLine)
        {
            StringBuilder strOutput = new StringBuilder();
            if (!String.IsNullOrEmpty(outLine.Data))
            {
                try
                {

                    strOutput.Append(outLine.Data);
                    Debug.WriteLine(strOutput);
                    buffer = encoder.GetBytes("2 "   outLine.Data  "\n");
                    networkStream = newclient.GetStream();
                    networkStream.Write(buffer, 0, buffer.Length);
                    networkStream.Flush();
                }
                catch (Exception err) { }
            }
        }

CodePudding user response：

If the lines are separated by \n instead of \r\n, simply use a string replace:

strdata = strdata.Replace("\n", "\r\n");

Then the TextBox should display the lines correctly.

Note that e.g. on Unix/Linux the defualt line separator is \n (line feed, LF). On Windows it's \r\n (carriage return / line feed, CR/LF).
