Read in string instead of chars

The Server is sending 20 characters at a time...but the client is only receiving a few characters (one or two characters) at a time.

How can I make the client receive the entire string being sent from the server all at once?

public void OnDataReceived(IAsyncResult asyn)
            {
                  try
                  {
                        SocketPacket theSockId = (SocketPacket)asyn.AsyncState ;
                        int iRx = theSockId.thisSocket.EndReceive (asyn);
                        //char[] chars = new char[iRx + 1];
                        char[] chars = new char[50];
                        System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
                        int charLen = d.GetChars(theSockId.dataBuffer, 0, iRx, chars, 0);
                        System.String szData = new System.String(chars);


                        WaitForData();
                  }
                  catch (ObjectDisposedException )
                  {
                        System.Diagnostics.Debugger.Log(0,"1","\nOnDataReceived: Socket has been closed\n");
                  }
                  catch(SocketException se)
                  {
                        MessageBox.Show (se.Message );
                  }
            }

Here is what the Server side is running:

void SendData()
            {
                  try
                  {
                        //Object objData = richTextBoxSendMsg.Text;
                        Object objData = linesFromFile[curLine];
                        byte[] byData = System.Text.Encoding.ASCII.GetBytes(objData.ToString ());
                        for(int i = 0; i < m_clientCount; i++)
                        {
                              if(m_workerSocket[i] != null)
                              {
                                    if(m_workerSocket[i].Connected)
                                    {
                                          m_workerSocket[i].Send (byData);
                                    }
                              }
                        }

                  }
                  catch(SocketException se)
                  {
                        MessageBox.Show (se.Message );
                  }
            }

In other words, the Server is sending

BEGIN

The client is receiving:

B

then

E

then

G

then

I

then

N

I want it to grab "BEGIN" all at once, just as the Server is sending it.

the following sample code might be usefull --

Private Sub ReceiveClientData(ByVal asyncResult As IAsyncResult)
Dim intcount As Integer
Try
SyncLock objClient.GetStream
intcount = objClient.GetStream.EndRead(asyncResult)
End SyncLock

If intcount < 1 Then
RaiseEvent Disconnected(Me)
Exit Sub
End If

ByteToString(bClientData, intcount)

SyncLock objClient.GetStream
objClient.GetStream.BeginRead(bClientData, 0, 1024, AddressOf ReceiveClientData, Nothing)
End SyncLock

Catch e As Exception
RaiseEvent Disconnected(Me)
End Try
End Sub

Private Sub ByteToString(ByVal Bytes() As Byte, ByVal intCount As Integer)
Dim intIndex As Integer
For intIndex = 0 To intCount - 1
If Bytes(intIndex) = 94 Then
RaiseEvent DataReceived(Me, objText.ToString)
objText = New StringBuilder
Else
objText.Append(ChrW(Bytes(intIndex)))
End If
Next
End Sub

Hi knowlton,

try converting the byte array to a string then send it as a string instead of a byte array, I have always send these things as a string in these type of cases.

Cheers!
