There's in fact a more radical solution, and that should be available in C# as it is in the generic SWIG .i files In Python (and likely the same in C#): gdal.GDALDestroyDriverManager() gdal.AllRegister() > > Instead, we tried algorithm you proposed with OGR > Driver.DeRegister()/Register() : this does not work, csv change is not > taked into account (csv file seems to be cached) Yes, Driver.DeRegister() just removes the driver from the list of drivers that are tried, but that doesn't destroy it.

Re: [gdal-dev] S57 objects’ catalog reload
Hi Even,
Thank you for your quick answer,
We work with C#, and unfortunately, we didn’t find GDALDriverManager API.
Instead, we tried algorithm you proposed with OGR
Driver.DeRegister()/Register() : this does not work, csv change is not taked
into account (csv file seems to be cached)

If your workflow is
open dataset 1
work with it
close dataset 1
change .csv file
open dataset 2
work with it
close dataset 2
then after "change .csv file", you could unload and reload the S57 driver so
that the S57ClassRegistrar singleton gets destroyed and reloaded, with
something like (untested):
GDALDriverManager* poDM = GetGDALDriverManager();
GDALDriver* poDrv = poDM->GetDriverByName("S57");
poDM->DeregisterDriver(poDrv);
delete poDrv;
RegisterOGRS57();
If you need to operate on 2 simultaneously opened datasets with different .csv
files, then changes would be needed in the S57 driver.
