Unexpected JSON token when reading DataTable. Expected StartArray, got StartObject

Question

I have a valid json (any json string) string and trying to convert it to Dataset but Newtonsoft.Json failed to do so.

Json text:

  {"root": {
  "Item": [
    {
      "Name": "Super Mario Bros",
      "Count": "14",
      "Price": "29,99",
      "Comment": "-No Comment-",
      "Artist": "N/A",
      "Publisher": "Nintendo",
      "Genre": "Video Games",
      "Year": "1985",
      "ProductID": "001"
    },
    {
      "Name": "The Legend of Zelda",
      "Count": "12",
      "Price": "34,99",
      "Comment": "-No Comment-",
      "Artist": "N/A",
      "Publisher": "Nintendo",
      "Genre": "Video Games",
      "Year": "1986",
      "ProductID": "002"
    }
  ]
}
}

Code:

var table = JsonConvert.DeserializeObject<DataSet>(jsonText);

Error:

Unexpected JSON token when reading DataTable. Expected StartArray, got StartObject. Path 'root', line 1, position 9.

Edit 1:

user can pass any type of json and i need to convert it to DataSet for the above example "root" element can contain any other property like "child1":"val1", "child2":"val2" and so forth. so, the output dataset will contain 2 tables namse root(should have one rows of properties 1 and 2) and item(should have 2 rows of type name,count,price etc).

Answer 1

The Json you showed is invalid.

It should look like this, to be load to the DataSet:

{
  "Item": [
    {
      "Name": "Super Mario Bros",
      "Count": "14",
      "Price": "29,99",
      "Comment": "-No Comment-",
      "Artist": "N/A",
      "Publisher": "Nintendo",
      "Genre": "Video Games",
      "Year": "1985",
      "ProductID": "001"
    },
    {
      "Name": "The Legend of Zelda",
      "Count": "12",
      "Price": "34,99",
      "Comment": "-No Comment-",
      "Artist": "N/A",
      "Publisher": "Nintendo",
      "Genre": "Video Games",
      "Year": "1986",
      "ProductID": "002"
    }
  ]
}

Code:

var dataSet = JsonConvert.DeserializeObject<DataSet>(jsonText);
var table = dataSet.Tables[0];
