I have the following string:

[
  [
    "costCenterRefNavigation.title",
    "contains",
    "hospital"
  ],
  "and",
  [
    "workCenterRefNavigation.workCenterTitle",
    "contains",
    "electrical"
  ],
  "and",
  [
    "scheduleType",
    "contains",
    "monthly"
  ]
]

I want to deserialize this string into Objects. I tried to created some classes as following:

class GridFilterModel
{
    public List<GridFilterElementModel> FilterItem { get; set; }
}
class GridFilterElementModel
{
    public string ColumnName { get; set; }
    public string Operand { get; set; }
    public string Value { get; set; }
}

Then, I tried to deserialize the string using the following code:

var filterElements = JsonConvert.DeserializeObject<GridFilterModel>(filter);

But there is a runtime error says:

Cannot deserialize the current JSON array, because the type requires a
JSON object (e.g. {“name”:”value”}) to deserialize correctly. To fix
this error either change the JSON to a JSON object (e.g.
{“name”:”value”}) or change the deserialized type to an array or a
type that implements a collection interface.

How can I fix this?
