TCPClient.GetStream() method problem

Hello there,
I am currently trying to pass a RTF type string through a TCPClient object from a client application to the server application. I am using a method called TexttoRtf() in the client application, and a method called RTFtoText() to convert the string to an backforth. these two methods seem to work perfectly in a standalone application. Here is the code for those methods:

public static string TexttoRtf(string text)
{
RichTextBox rtfTemp = null;
string result = string.Empty;
try
{
rtfTemp = new RichTextBox();
rtfTemp.Text = text;
rtfTemp.SelectAll();
//using (Font monospacedFont = new Font("Courier New", 10))
//{
// rtfTemp.SelectionFont = monospacedFont;
//}

result = rtfTemp.SelectedRtf.TrimEnd('\0');
}
catch (Exception er)
{
MessageBox.Show("In TextToRTF function --> "+er.Message); //exception handling code
}
return result;
}

public static string RtftoText(string text)
{
RichTextBox rtfTemp = null;
string result = string.Empty;
try
{
string temp = text;
rtfTemp = new RichTextBox();
MemoryStream ms= new MemoryStream(Encoding.UTF8.GetBytes(temp));
UTF8Encoding encoder = new UTF8Encoding(); //rtBox.Rtf

rtfTemp.Rtf = encoder.GetString(ms.ToArray());
result = rtfTemp.Text;

}
catch (Exception er)
{
MessageBox.Show("In RTF to Text function --> "+er.Message);
}
return result;
}

I am using these methods in the client and server application at appropriate places.
Problematic part in the client application:

tcpServer = new TcpClient();
tcpServer.SendBufferSize = 10000000;
tcpServer.ReceiveBufferSize = 10000000;

tcpServer.Connect(ipAddr, portNo);

StreamWriter swSender = new StreamWriter(tcpServer.GetStream());
string rtfTextTosend = TexttoRtf("hello Mike");
swSender.WriteLine(userRoomDetails);
swSender.Flush();

tcpServer is a TCPClient type object.
Here the variable rtfTextTosend gets a value like "{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
\uc1\pard\f0\fs17 hello Mike}
"
At the receiving Server end i am using a similar approach except a StreamReader to retrieve the value like this :
StreamReader srReceiver = new System.IO.StreamReader(tcpClient.GetStream());

string readLine =srReceiver.ReadLine();
MessageBox.Show(readLine);

But here the message box displays only part of the RTF type string used at the application:
"{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
"

this part of the RTF is missing:
\uc1\pard\f0\fs17 hello Mike}

Sp when i try to revert it back to plain text using RTFtoText() method, i get a null value. I even tried increasing the Send and receive buffer sizes of the TCPClient objects both in the client and server application. I am unable to get the missing RTF part on my server side.

Does anybody know a solution for this please?
