how do i deal with float

mali

this is my code:

found_product[i] = new Product((int)(dr["productNum"]), (string)(dr["catalogNum"]), (string)(dr["item_Description"]), (string)(dr["productDescription"]), (int)(dr["productAmount"]),(string)(dr["supplier_name"]), (string)(dr["date"]).ToString(), (float)(dr["buyingPrice"]));

I have a problem with the "(float)(dr["buyingPrice"])" it's give me an error "Specified cast is not valid."

what can I do?

It depends on what the type of dr["buyingPrice"] actually is. If it's a double, you could do:

(float)(double)(dr["buyingPrice"])

If it's a decimal:

(float)(decimal)(dr["buyingPrice"])
