Displaying values from a Dictionary within a Dictionary within MVC Razor view

I'm not even sure this is possible with MVC Razor, but I would like to pass my Dictionary that includes another Dictionary to my view and display the child Dictionary keys and values.

public Dictionary<int, dynamic> Getdata(DateInfo dataInfo)
{

//Create a parent dictionary
Dictionary<int, dynamic> parentDict = new Dictionary<int, dynamic>();

//Load the child dictionary
for (int i = 0; i < list.Count; i++)
{
     //Create a child dictionary to store all values
     Dictionary<int, dynamic> dict = new Dictionary<int, dynamic>();

     parentDict[i] = dict;
     parentDict[i].Clear();
    if (beginningYear < DateTime.Now.Year)
    {
         //...code left out for brevity

        if (NumberOfYears > 1)
        {
            for(int j = 1; j < NumberOfYears; j++)
            {
               beginningYear = beginningYear + 1;

               //...code left out for brevity

               dict.Add(beginningYear, new { Month = 12, MonthlyAmount = nextYearAmount.premium, TotalYearAmount = TotalYearAmount });
            }
        }
     else
     {
         //...code left out for brevity
     }
}
return parentDict;

My Parent Dictionary values looks like this:

[0] = {[0, System.Collections.Generic.Dictionary`2[System.Int32,System.Object]]}

[1] = {[1, System.Collections.Generic.Dictionary`2[System.Int32,System.Object]]}

My Child Dictionary values like this:

[0] { Month = 5, MonthlyAmount = 99.90, TotalYearAmount = 499.50 }

[1] { Month = 12, MonthlyAmount = 399.90, TotalYearAmount = 1499.50 }

[2] { Month = 12, MonthlyAmount = 499.90, TotalYearAmount = 1794.50 }

[0] { Month = 9, MonthlyAmount = 999.90, TotalYearAmount = 6499.50 }

[1] { Month = 12, MonthlyAmount = 3.90, TotalYearAmount = 39.50 }

Within the view:

 @foreach (var item in Model.MyDictionary[0])
 { 
     @item.Value
 }

That code will display the child value, which is:

 { Month = 5, MonthlyAmount = 99.90, TotalYearAmount = 499.50 }

Is it possible to reference Month, MonthlyAmount, TotalYearAmount?

     @item.Value.Month

will not work. 'object' does not contain a definition for 'Month'

And I would like to go through the parent dictionary to reference the child. If I use:

 @foreach (var item in Model.MyDictionary[1])
 { 
     @item.Value
 }

That will display

 { Month = 9, MonthlyAmount = 999.90, TotalYearAmount = 6499.50 }

This code will not work, but I would like to get the values such as:

 @foreach (var item in Model.MyDictionary[0][1])
 { 
     @item.Value.TotalYearAmount 
 }

and the value displays: 1499.50

Any advice is appreciated.

Change your line 

dict.Add(beginningYear, new { Month = 12, MonthlyAmount = nextYearAmount.premium, TotalYearAmount = TotalYearAmount });

with usage of ExpandoObject to 

dynamic expandoObject = new ExpandoObject();
expandoObject.Month = 12;
expandoObject.MonthlyAmount = nextYearAmount.premium;
expandoObject.TotalYearAmount = TotalYearAmount;
dict.Add(beginningYear, expandoObject);

If your Dictionary is longer, you can use following link to convert it in a method: http://theburningmonk.com/2011/05/idictionarystring-object-to-expandoobject-extension-method/

You can use dynamic instead of var like this:

 @foreach (dynamic item in Model.MyDictionary[0][1])
 { 
     @item.Value.TotalYearAmount 
 }
