NHapi is a port of the original project HAPI.

NHapi allows Microsoft .NET developers to easily use an HL7 2.x object model. This object model allows for parsing and encoding HL7 2.x data to/from Pipe Delimited or XML formats. A very handy program for use in the health care industry.

This project is NOT affiliated with the HL7 organization. This software just conforms to the HL7 2.x specifications.

Key Benefits:

  • Easy object model
  • Microsoft .NET 3.5 library that conforms to HL7 2.1, 2.2, 2.3, 2.3.1, 2.4, and 2.5 specifications
  • Can take a pipe delimited or XML formated HL7 2.x message and build the C# object model for use in code
  • Can take the C# HL7 object model and produce pipe delimited or XML formatted HL7
  • FREE! (You can't beat that price) and open source
  • Fast


NHapi currently targets version 3.5 of the .NET Framework
