Retrieving ulong from Sqlite relsults in NotSupportedException

I've got some hash values (as ulong) saved to a Sqlite database by a console application. Now I'd like to retreive those values inside a Windows Store App, unfortunately I get a NotSupportedException saying "Don't know how to read System.UInt64". Can't I use ulong values in my database? The DB is populated and the hash-field does seem to be ulong, at least thats what Database .NET tells me.

Solution

  • SQLite's integers have 64 bits, but are signed.

    You should cast your hash values to/from long.
