[RESOLVED] long? CompareTo

the type 'long' has a 'compareto()' method but how would you do it if the variable is type 'long?' ?

Basically got a class that contains a variable called FileSize which contains null if it is a folder and other files should have a value for it..so for sorting the specific field, I will need to do a 'compareTo()' but don't seem to do it.

Any ideas? Thanks

nullable<long> has a Compare method if it's any help.

You can also specify your own comparison methods.

Thanks for the reply..

am I doing something wrong with this code then?

Code:

---

Nullable.Compare<FileSystemItem>(item1.Size, item2.Size);

---

Are you comparing nullable FileSystemItems or nullable longs?

Code:

---

int comp = Nullable.Compare<long>(item1.Size, item2.Size);
//or
int comp = Nullable.Compare(item1.Size, item2.Size);

---

The latter line of code worked wonders.

Thanks very much ^_^
