{
  "ItemDiscount": {
    "enabled": true,
    "enableItemSelectionOnTenderScreen": true,
    "allowDiscountsForCanAdd": true,
    "allowDiscountsForExtra": true,
    "allowDiscountForVMUpcharge": true
  }
}

I am trying to read this file value in my api.

C#

var filedata = File.ReadAllText(jsonFilePath);

var jsonFileData = JsonConvert.DeserializeObject<T>(filedata);

filedata variable value->>

"{\r\n  \"ItemDiscount\": {\r\n    \"enabled\": true,\r\n    \"enableItemSelectionOnTenderScreen\": true,\r\n    \"allowDiscountsForCanAdd\": true,\r\n    \"allowDiscountsForExtra\": true,\r\n    \"allowDiscountForVMUpcharge\": true\r\n  }\r\n}"

What I have tried:

I suppose that some idea of what type T is would help.

Start by using a converter to generate sample classes from the JSON: Convert JSON to C# Classes Online - Json2CSharp Toolkit[^] is the one I use.

Then compare that to the classes you expect the deserialize to generate. If they aren't very, very similar, then you won't get what you want.

And I suspect that's the problem: you don't normally use a class called "T" in generics as it's generally a placeholder for the generic Type specifier that you explicitly of implicitly use when you run use the generic function / class.
