Casting error in MVC

Question

I am developing a MVC app. with razor syntax. I am trying to delete one value from another.

  @{
   double DeductedAmount1 = @Model.SanctionedAmount - @Model.DeductionAmount;         
  }

This showing error as

Cannot implicitly convert type 'double?' to 'double'. An explicit conversion exists (are you missing a cast?)

Issue Solved , thanks To Darren Davies

dAmount1 = (double)@Model.SanctionedAmount.Value - (double)@Model.DeductionAmount;

Answer 1

Use double?

double? DeductedAmount1 = @Model.SanctionedAmount - @Model.DeductionAmount; 

Looks like SanctionedAmount or DeductionAmount are type of nullable double

You can also use .Value on the Nullable double. For instance if SanctionedAmount is of type double? and DeductionAmount is of type double you can do:

 double DeductedAmount1 = @Model.SanctionedAmount.Value - @Model.DeductionAmount;

Also you can use a cast

 double DeductedAmount1 = (double)@Model.SanctionedAmount.Value - (double)@Model.DeductionAmount;
