Deserializing JSON array into strongly typed .NET object

shosho s

7y5k.NET

When I can call the 3rd party api to get back data i keep getting the error "

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1....."

my json file format is like shown below :

{

"meals": [

{

"idMeal": "52771",

"strMeal": "Spicy Arrabiata Penne",

"strDrinkAlternate": null,

"strCategory": "Vegetarian",

"strArea": "Italian",

"strInstructions": "Bring a large pot of water to a boil. Add kosher salt to the boiling water, then add the pasta. Cook according to the package instructions, about 9 minutes.\r\nIn a large skillet over medium-high heat, add the olive oil and heat until the oil starts to shimmer. Add the garlic and cook, stirring, until fragrant, 1 to 2 minutes. Add the chopped tomatoes, red chile flakes, Italian seasoning and salt and pepper to taste. Bring to a boil and cook for 5 minutes. Remove from the heat and add the chopped basil.\r\nDrain the pasta and add it to the sauce. Garnish with Parmigiano-Reggiano flakes and more basil and serve warm.",

"strMealThumb": "https://www.themealdb.com/images/media/meals/ustsqw1468250014.jpg",

"strTags": "Pasta,Curry",

"strYoutube": "https://www.youtube.com/watch?v=1IszT_guI08",

"strIngredient1": "penne rigate",

"strIngredient2": "olive oil",

"strIngredient3": "garlic",

"strIngredient4": "chopped tomatoes",

"strIngredient5": "red chile flakes",

"strIngredient6": "italian seasoning",

"strIngredient7": "basil",

"strIngredient8": "Parmigiano-Reggiano",

"strIngredient9": "",

"strIngredient10": "",

"strIngredient11": "",

"strIngredient12": "",

"strIngredient13": "",

"strIngredient14": "",

"strIngredient15": "",

"strIngredient16": null,

"strIngredient17": null,

"strIngredient18": null,

"strIngredient19": null,

"strIngredient20": null,

"strMeasure1": "1 pound",

"strMeasure2": "1/4 cup",

"strMeasure3": "3 cloves",

"strMeasure4": "1 tin ",

"strMeasure5": "1/2 teaspoon",

"strMeasure6": "1/2 teaspoon",

"strMeasure7": "6 leaves",

"strMeasure8": "spinkling",

}

]

}

What i have tried is this but im still getting the same error.

var EmpInfo = JsonConvert.DeserializeObject>(EmpResponse);

I have also tried this, but all the values returned are null :

var test = JsonConvert.DeserializeObject(EmpResponse);

Any help is appreciated.

I think your Model "WebApiClass" is not matching with json object you are trying to Deserialize.

Create your WebApiClass like this, and then try below code

var EmpInfo = JsonConvert.DeserializeObject(EmpResponse);
public class Meal

{

    public string IdMeal { get; set; }

    public string StrMeal { get; set; }

    public object StrDrinkAlternate { get; set; }

    public string StrCategory { get; set; }

    public string StrArea { get; set; }

    public string StrInstructions { get; set; }

    public string StrMealThumb { get; set; }

    public string StrTags { get; set; }

    public string StrYoutube { get; set; }

    public string StrIngredient1 { get; set; }

    public string StrIngredient2 { get; set; }

    public string StrIngredient3 { get; set; }

    public string StrIngredient4 { get; set; }

    public string StrIngredient5 { get; set; }

    public string StrIngredient6 { get; set; }

    public string StrIngredient7 { get; set; }

    public string StrIngredient8 { get; set; }

    public string StrIngredient9 { get; set; }

    public string StrIngredient10 { get; set; }

    public string StrIngredient11 { get; set; }

    public string StrIngredient12 { get; set; }

    public string StrIngredient13 { get; set; }

    public string StrIngredient14 { get; set; }

    public string StrIngredient15 { get; set; }

    public object StrIngredient16 { get; set; }

    public object StrIngredient17 { get; set; }

    public object StrIngredient18 { get; set; }

    public object StrIngredient19 { get; set; }

    public object StrIngredient20 { get; set; }

    public string StrMeasure1 { get; set; }

    public string StrMeasure2 { get; set; }

    public string StrMeasure3 { get; set; }

    public string StrMeasure4 { get; set; }

    public string StrMeasure5 { get; set; }

    public string StrMeasure6 { get; set; }

    public string StrMeasure7 { get; set; }

    public string StrMeasure8 { get; set; }

}



public class WebApiClass

{

    public List Meals { get; set; }

}

public object strDrinkAlternate { get; set; }
public string strCategory { get; set; }

public string strIngredient6 { get; set; }
public string strIngredient7 { get; set; }
public string strIngredient8 { get; set; }
public string strIngredient9 { get; set; }
public string strIngredient10 { get; set; }
public string strIngredient11 { get; set; }
public string strIngredient12 { get; set; }
public string strIngredient13 { get; set; }

public string strMeasure5 { get; set; }
public string strMeasure6 { get; set; }
public string strMeasure7 { get; set; }
public string strMeasure8 { get; set; }
}
public class RootObject
{
public List meals { get; set; }
}

Use above class
basically ur json in format of jarray
JArray body = JArray.Parse("place here your object");

RootObject jsonobjects= body.ToObject();

any issues please ping me if it helps please accept the answer..
