C# JSON deserialisation

Question

5.00/5 (1 vote)

See more:

{ "Description": "This registry defines the events for the management processor.",
"Id": "Events.json",
"Messages": {
"AEPSecureEraseFailed": {
"Description": "Secure Erase of Intel Optane DC Persistent Memory has failed.",
"Message": "Secure Erase of Intel Optane DC Persistent Memory has failed",
"ParamTypes": ["string", "string", "string"],
"Resolution": "Retry Secure Erase. Please contact HPE Support if issue persists.",
"Severity": "Critical"
},
"AdapterConfigurationChange": {
"Description": "The specified adapter has had a configuration change.",
"Message": "The adapter in slot %1 has had a configuration change.",
"Resolution": "None",
"Severity": "Ok"
},
"FanRemoved": {
"Description": "The fan is removed.",
"Message": "The fan is removed.",
"Resolution": "None",
"Severity": "Warning"
}
},
"Name": "Event Registry"
}

What I have tried:

public class AEPSecureEraseFailed
{
public string Description { get; set; }
public string Message { get; set; }
public List<string> ParamTypes { get; set; }
public string Resolution { get; set; }
public string Severity { get; set; }
}

public class AdapterConfigurationChange
{
public string Description { get; set; }
public string Message { get; set; }
public string Resolution { get; set; }
public string Severity { get; set; }
}

public class FanRemoved
{
public string Description { get; set; }
public string Message { get; set; }
public string Resolution { get; set; }
public string Severity { get; set; }
}

public class Messages
{
public AEPSecureEraseFailed AEPSecureEraseFailed { get; set; }
public AdapterConfigurationChange AdapterConfigurationChange { get; set; }
public FanRemoved FanRemoved { get; set; }
}

public class RootObject
{
public string Description { get; set; }
public string Id { get; set; }
public Messages Messages { get; set; }
public string Name { get; set; }
}

Is there any other way of deserialising other than:
public class Messages
{
public AEPSecureEraseFailed AEPSecureEraseFailed { get; set; }
public AdapterConfigurationChange AdapterConfigurationChange { get; set; }
public FanRemoved FanRemoved { get; set; }
}
so that we do not have to write the same lines for the other 256 left events

Json.NET[^] may also be useful.

As you're starting out with serialization of JSON data, this article answers this question and many others that you will have: Working with JSON in C# & VB[^]

Since all of the messages seem to share a common set of properties, try something like this:

C#

public class ErrorMessage
{
    public string Description { get; set; }
    public string Message { get; set; }
    public string Resolution { get; set; }
    public string Severity { get; set; }
    
    // Add any other interesting properties from the different messages here.
    // Any which are not available for this message will be null.
    public List<string> ParamTypes { get; set; }
}

public class RootObject
{
    public string Description { get; set; }
    public string Id { get; set; }
    public string Name { get; set; }
    public Dictionary<string, ErrorMessage> Messages { get; set; }
}

Copy your json string to the clipboard and then from the edit menu in visual studio choose paste special.

This is a design-time operation. OP's requirements seem to happen at run-time.

I would like to recommend
json2csharp - generate c# classes from json[^]
This site will generate a C# class from any valid JSON string.
There is no need to write a corresponding C# class by hand.
