“does not contain a definition…and no extension method..” error

Question

I have the following error message:

\'System.Collections.Generic.Dictionary\' does not
contain a definition for \'biff\' and no extensi         


        

Answer 1

You need to access the Value of the Dictionary for a given key. Something along these lines.

foreach(var item in dbContext.DBView)
{
    foreach(var key in cart.Keys)
    {
        cart[key].biff = item.biff;
    }
}

Answer 2

The problem is this part: cart.biff. cart is of type Dictionary<int, SpoofClass>, not of type SpoofClass.

I can only guess what you are trying to do, but the following code compiles:

Dictionary<int, SpoofClass> cart = new Dictionary<int, SpoofClass>();
int i=0;
foreach (var item in dbContext.DBView)
{
    cart.Add(i, new SpoofClass { biff = item.biff });
    ++i;
}
