convert JSON file into a C# list without using a helper class

Question

is there a way to convert JSON file into a C# list without using a helper class ?

i have read some articl about using Dynamics, but i don't know how to loop through items inside dynamic object.

here what i have found so far :

StreamReader r = new StreamReader(@"C:\Users\barras\Desktop\P922 test File\Itacc_Files\OpenNet_P922x_NM_31698.json");
  string jsonString = r.ReadToEnd();
            dynamic  JsonDyn= Newtonsoft.Json.JsonConvert.DeserializeObject(jsonString);

now, i need to loop through each item in dynamic object JsonDyn and fill the data into a list.

here Json File structure :

{
    "OpenNet_PoGnd":
        {
            "Pins": ["CBGND_1","CBD_7","CT2_4","CBD_6" ]
        },
    "OpenNet_L36":
        {
            "Pins": ["CBF_22","CBF_9"]
        },
    "OpenNet_L37":
        {
            "Pins": ["CT2_1","CBF_20","CT1_2","CBF_18"]
        },
    "OpenNet_IC104":
        {
            "Pins": ["CN5_4","CBC_40"]
        },
......
}

What do you mean by "without using a helper class"? Do you mean "without using a strongly-typed deserialization-target object"? — David L

Not a problem. Perhaps if you expand on what you are trying to accomplish and why a helper class isn't considered a viable solution? Then we can gear our answers around that. — James Shaw

Can you parse the json to a dictionary for example? Then you can access via Key/Value pairs. — James Shaw

try this :

dynamic array = JsonConvert.DeserializeObject(jsonString );

  foreach(var item in array)
  {
    String Str =  item.Pins;
  }
