Not in C#. There is a dblocate_servers_ex
function (documentation) that you can use from a C/C++ application, or you can spawn the dblocate utility and capture the output, but that's about it.
The dblocate utility, FYI, does not make any TCP connections. It sends out broadcast packets which SQL Anywhere servers respond to, and then lists the responses.
Note that the point of the -sb 0
switch is to make it impossible to find the server using dblocate. If it were possible to find it anyway, the switch would be useless.
Full disclosure: I work for SAP in SQL Anywhere engineering.
