Deserialize a DataSet

string json = @"{
  'Table1': [
    {
      'id': 0,
      'item': 'item 0'
    },
    {
      'id': 1,
      'item': 'item 1'
    }
  ]
}";

DataSet dataSet = JsonConvert.DeserializeObject<DataSet>(json);

DataTable dataTable = dataSet.Tables["Table1"];

Console.WriteLine(dataTable.Rows.Count);
// 2

foreach (DataRow row in dataTable.Rows)
{
    Console.WriteLine(row["id"] + " - " + row["item"]);
}
// 0 - item 0
// 1 - item 1
