How to get the elements in object array list

Question

enter image description here I tried to get the value of an object[] but using foreach didn't work well. object[] contains a list of object[] how can I fetch the data

public void SaveBottonTable(string dimension)
{
    JavaScriptSerializer json_serializer = new JavaScriptSerializer();
    object[] routes_list = 
        (object[])json_serializer.DeserializeObject(dimension);
                GlobalConstant.holeconfiguration = routes_list;//list is referred in the image
    foreach(object hole in routes_list)
    {
        hole[0]//shows error
    }
}

how to get the value of the first object[]

object hole represents single object. when you do hole[0] you are trying to use single object as array of objects. That's why you are getting an error. You should do var routes = hole as object[]; in foreach loop an then you can access individual objects from routes by doing routes[0], routes[1] etc.. — Chetan

Since each element is an array of strings you should convert each object to array and then index it.

foreach(object hole in routes_list)
{
   var elements = hole.ToArray();
//then you can access elements[0] and elements [1]
}

However, I think it would be better if the format was "Key":"Value" Example: { "object-ID":"1234123cfrewr", "view" : "Cover", . . .}

Be careful with Collection.Generics since you have a couple of Dictionaries there. They will need extra care.

It looks like your json contains a dictionary. In that case I would deserialize it to the appropriate type Dictionary<string, object>. Then when looping through it you can either get the key using hole.Key or the value using hole.Value.

This way:

object[] list = new object[]
{
    new object(),
    1,
    "ciao",
    new object[] { 1, 2, 3, 4, 5 },
    "pizza",
    new object[] { "ciao", "pizza" },
    new List<object>(){ 123, 456 }
};

foreach (ICollection collection in list.OfType<ICollection>())
{
    //Here you can work with every collection found in your list
}
