One typically would use a Nullable if the variable needs a "I don't know the value" state (similar to "null" for reference types). For some value types, you don't need all possible values and can use a special value, such as DateTime.MinValue; for others, all conceivable values could be meaningful and the "no value" state needs a separate something (which happens to be a hidden boolean in Nullable, so they are costing more memory and more cycles).
I'm not very fond of Nullable, one can easily do without them.
I created a web service and i created also many classes below.
when i add it as a web reference, i can access all classes just one that contain public string variable is not shown ?
any suggestion !!
