If you are using something like a queue, you will have a message type, and embedded in that message type you will sometimes see a serialized object. To get the object back, you will need to deserialize the message and then deserialize the embedded object.

If you serialize an already serialized string, the serializer will replace double quotes with \u0022. Here is a way to get back the familiar \".

This is one of those posts that I write for my future self. Here’s how to deserialize JSON from a file in C#. It also lists multiple ways to create the C# model from the JSON.

Sometimes a Lambda function can’t deserialize the JSON it receives because the model is wrong or the JSON is not as expected. This post shows how to output the raw JSON to CloudWatch logs so you fix the problem.

When deserializing JSON from a console application or library, you have to handle unusual casing of JSON key names, and numbers represented as strings yourself. This is done with a couple of serialization options.

Working with Json directly in C# has always been a problem, but as Json becomes more common the problems mount. I was using AWS Step Functions recently and wanted to pass the Json string output from a Lambda running .NET Core 3.1. As with all things C# Json string related, it was not easy.

Full source code available here. This is a follow up to my previous post where I used dynamic and JSON files to make querying ElasticSearch with a HttpClient much easier.

The Problem It’s hard to get the details of an exception from a Web Api response when calling Web Api from a C# program. (Skip to the solution if you don’t care about the background), it even handles inner exceptions!
