If you want to see a sample in C#, download the [Azure IoT C# Samples](https://github.com/Azure-Samples/azure-iot-samples-csharp/archive/main.zip). Unzip the master.zip file. The Visual Studio solution *SimulatedDevice*'s Program.cs file shows how to encode and submit messages to an IoT Hub. This is the same sample used for testing the message routing, as explained in the [Message Routing tutorial](tutorial-routing.md). At the bottom of Program.cs, it also has a method to read in one of the encoded files, decode it, and write it back out as ASCII so you can read it.
