How to convert a json values to a dictionary in c# and address them with a string value?

I'm trying to make a dictionary of a json values to index them with a string. I'm using Newtonsoft to deserialze json string. my json is :

 {
    "financialPositions": [
      {
        "fieldName": "Assets",
        "periodEndToDateValue": 0.0,
        "pastYearEndToDateValue": 0.0,
        "description": "\u062f\u0627\u0631\u0627\u06cc\u06cc\u200c\u200c\u0647\u0627",
        "percentChanges": 0.0,
        "rowClass": "GroupHeader"
      },
      {
        "rowClass": "ComputationalRow",
        "fieldName": "ListedCapital",
        "description": "\u0633\u0631\u0645\u0627\u06cc\u0647",
        "percentChanges": 0.0,
        "currentPeriodEndToDateValue": 1.0,
        "pastSimillarEndToDateValue": 1.0,
        "pastYearEndToDateValue": 1.0
      }
    ]
  }

I used this classes :

public class RootObject
{
    public FinancialPositions[] financialPositions{ get; set; }
}

public class FinancialPositions
{
    public string fieldName { get; set; }
    public double periodEndToDateValue { get; set; }
    public double pastYearEndToDateValue { get; set; }
    public string description { get; set; }
    public float percentChanges { get; set; }
    public string rowClass { get; set; }
}

and I use this to deserialize the json string : 

RootObject oRootObject = new RootObject();
oRootObject  = JsonConvert.DeserializeObject<RootObject>(jsonstring);

what changes need to address them like below? 

oRootObject.financialPositions["Assets"]

You can define an indexer [] for your object.

public class RootObject
{
    public FinancialPositions[] financialPositions{ get; set; }

    public object this[string name]
    {
          get { return financialPositions.FirstOrDefault(f => f.fieldName  == name); }
          set { }
    }
}

Then call

oRootObject["Assets"] it returns your object

{
        "fieldName": "Assets",
        "periodEndToDateValue": 0.0,
        "pastYearEndToDateValue": 0.0,
        "description": "\u062f\u0627\u0631\u0627\u06cc\u06cc\u200c\u200c\u0647\u0627",
        "percentChanges": 0.0,
        "rowClass": "GroupHeader"
 }
