Exception adding an escaped string as field to Segment

[manosg80]

Describe the bug I was trying to find out why it throws an exception when adding a particular field to header so I broke down the string to p1 and p2.

To Reproduce Just run the following code:

 Segment mshSegment = new Segment("MSH", new HL7Encoding());
            mshSegment.AddNewField("|", 1);
            string p1 = @"^~\";
            string p2 = @"&";
            string p3 = p1 + p2;
            mshSegment.AddNewField(p3, 2); 

Expected behaviour Should add the field

Don't know if this is HL7 dotnetcore issue or NHAPI

@manosg80 I've never seen that technique for creating segments before, have you tried newing up a MSH segment instead?

I'm not saying it's not an issue just never seen it done that way before.

Maybe this will help. https://saravanansubramanian.com/hl72xnhapicreatemessage/

Yes, actually using the MSH Segment was how I bypassed the issue. I had found this approach in a couple of tutorials with a more 'loose' approach as to what MSH fields should be present. I guess the '\' character is used for delimiting and hence can't exist in a field - at least that's what I think.

@manosg80 The code samples provided seem to be from HL7 dotnetcore not nhapi.

You are right, hence my previous comment that I might be knocking the wrong door. Apologies!
