See MSDN.
In that case, merely use
myNullableVariable.Value(if you’re sure it has a value), or(myNullableVariable.HasValue)?myNullableVariable.Value:somedefaulthereif you’re not.One can also use
GetValueOrDefault()if one doesn’t care if the default is a specific value when the nullable really is null.The last way to do it is this:
myNullableVariable.Value ?? defaultvalue.See, technically a
MyType?variable is aNullable<MyType>under the covers. There are no implicit or explicit casts between the two, so what you need to do is extract the value out of theNullablemanually. The third way i listed is the most succinct (and best?) way to do it, to that would probably be best in most cases.
