Small changes to the roles class

The roles class has a getrole (guid roleid, bool cacheable) method. An exception is thrown when the role cannot be found. Throw   New Csexception (csexceptiontype. resourcenotfound, " Role not found: "   + Roleid. tostring ());

The exception type here is resourcenotfound, which should be changed to the rolenotfound type.

Throw   New Csexception (csexceptiontype. rolenotfound, " Role not found: "   + Roleid. tostring ());

Another method to be modified is getrole (string rolename, bool cacheable)
