Declaration
public static long UnboxIntegerToLong(
object integer
)Summary
C# does not allow a boxed integer type to be unboxed as anything other than the true type of the boxed
integer. This utility function unboxes the integer as the correct type and then casts it to a long, returning
the result. Throws an exception if the object is null or not one of the built-in integer types. Does not
support unboxing of a ulong because the cast to long would be lossy and misleading. Will throw an exception
when given a boxed ulong.
