How to send string from c# to LabView over socket?

[vsanghvi]

The LabView application that I have creates a server coacket and accepts only "string" data. My C# application creates a client socket and tries to send "byte" data over socket. How can I make this work? C# socket function does not allow me to send "string" data. It forces me to convert the data to byte array.

vsanghvi,

Im a bit confused with exactly what were doing here. I understand were trying to pass data from a LV application to some C# code, but are we using data sockets? Also, are you using measurement studio for your C# code, and if so what version? 

Can you give us a snippet of code from the client and server side to help show us what youre doing?

Hi,

Sorry for the confusion.

LV is creating the server data socket and I'm trying to create client from C# (not using measurement studio). The byte array that I was sending from C# was not being read by LV. I found the issue was with the way I was encoding the string in C#.

C# code:

string strCommand;

byte[] byData = System.Text.Encoding.UTF8.GetBytes(strCommand);

int nBytes = clientSock.Send(byData);

Instead of UTF8 I was trying ASCII and UNICODE, which was not doing the right string to byte conversion. Everything is working fine now.

Thanks
