My HTTP response data includes a field that is structured as a Dictionary<string,object>. Accessing the Object in debug mode shows me what I expect to see, i.e.

ValueKind = Object:

{ "someProp" : "someValue",
"anotherProp" : "anotherValue" .. }

=> the object therefore contains the large json formatted data that I need to access. However, I can't figure out how to do that .. The commonly suggested method returns null:

var myValue = Odata.GetType().GetProperty("someProp").GetValue(Odata, null);

which makes me think there is something I should be serializing which I am not and regardless how much I tried, I can't find any methods to work.

Here is some more info, if it is not enough I will add whatever is needed. I broke it down a lot to try to show clearly what I am getting each step):

// assume Odata = the Object value from the dictionary

//perform reflection
var type = Odata.GetType()   // this gives System.Text.json.JsonElement

//get type properties at runtime 
var props = type.GetProperties()  
//returns array of 2 : 
//System.Text.Json.ValueKind and System.Text.json.JsonElement

//attempting to access my properties in the JsonElement
var someValue= type.GetProperty("someProp").GetValue(Odata,null) //this gives null

I don't necessarily want an exact solution, but pointing me to the right place to read would also be very useful!

When you do GetType().GetProperty() you're using the GetProperty() method from Type class, you're using reflection. You want to use the GetProperty method of JsonElement class instead:

var myValue = Odata.GetProperty("someProp").GetString();

  • Thank you for your input. The Odata is still an Object that doesn't have a GetProperty() method associated with it. I see JsonElement should have TryGetProperty and GetProperty() methods, but neither of them seem to work. – ISquared Feb 14 '23 at 13:28
  • @Isquare1 Have you declared Odata as `object`? Because by your code (the return of `GetType`), it is in fact a `JsonElement`, so you just have to cast it, like `((JsonElement)Odata).GetProperty("someProp").GetString();` – Magnetron Feb 14 '23 at 13:30

    Casting the object to JsonElement worked, thank you infinite number of times! I set your answer as the accepted one :) – ISquared Feb 14 '23 at 13:37
