How do I easily modify *any* property/object/nested object of C# deserialized .json?
config/data.json
{
"title": "XYZ",
"obj1": {
"s1": -1,
"s2": "auto",
"s3": false,
},
"obj2": {
"s1": true,
"s4": [
[5,0],
[4,1]
]
},
"obj3": [
{
"s3": "s",
}
],
}
program.cs
// Classes for JSON de-serialization
`public class Obj1
{
public int s1 { get; set; }
public string s2 { get; set; }
public bool s3 { get; set;}
}
public class Obj2
{
public bool s1 { get; set; }
public IList<IList<int>> s4 { get; set; }
}
public class Obj3
{
public string s3 { get; set; }
}
public class Example
{
public string title { get; set; }
public Obj1 obj1 { get; set; }
public Obj2 o2 { get; set; }
public IList<Obj3> obj3 { get; set; }
}
//Methods to modify JSON
private static string rigJsonPath =
Path.Combine(AppDomain.CurrentDomain.BaseDirectory, Path.Combine("config", "data.json"));
public static Example ReadAndDeserialize()
{
string json = File.ReadAllText(rigJsonPath);
Example ex = JsonSerializer.Deserialize<Example>(json)!;
return ex;
} public static void SerializeAndWrite(Example ex) { string json = JsonSerializer.Serialize(ex); File.WriteAllText(rigJsonPath, json); } public static void ModifyProperty(Example ex, string propertyName, object propertyValue) { switch (propertyName) { case "obj1.s1": ex.obj1!.s1 = (int)propertyValue; break; // etc } } I want to be able to modify any property/object of JSON through a method in C#. I'd like to create a universal method for this task. The switch is a monkey solution, can't write for lots of objects.

You can't
Really? 🥲
Welcome to a strongly and statically-typed language
You can't just willy-nilly access whatever by whatever and set it to whatever
Maybe with reflections
Or with
JsonDocument or something
But there's no reason to
Just... modify the object, without any random helper method
Foo.Bar.Baz.Quz = 58Okay but what if I want to be able to modify each element? I want an option to do so. Should I create a method for each property then?
Each property will have its own function
There's no way to solve this?
Essentially I wanted to be able to modify any property from the command line, make it interactive and fast when working with bigger Json files
Some sort of a weird JSON editor?
Kind of
Json should be edited manually? Isn't it sort of database?
I'm sorry if I sound gullible, I'm very much a beginner
Well, JSON is a human-readable and human-editable format
So I don't see much of a reason for some CLI editor to exist, if you can just open the file in Notepad
What kind of light database I could work with to interact with through the CLI then
Damn, it is so right, json is human readable
