if else statement in Razor is not functioning

Question

I am using an if else in Razor view to check for null value like this:

 @foreach (var item in Model)
    {
        
                  


        

Answer 1

You have to use the @()

            @if (item.Amount == null)
            {
                @("--");
            }
            else
            {
                @String.Format("{0:0.##}", item.Amount)
            }

As noted in the comments and other answers, the Html.Display is not for displaying strings, but for displaying data from the ViewData Dictionary or from a Model. Read http://msdn.microsoft.com/en-us/library/ee310174%28v=VS.98%29.aspx#Y0
