i not using using keyword ?

this issue been while , referred many articles in stackoverflow things looking bad me .

thank suggestions

underlying provider failed open means, @ point database not reached, due wrong connection settings example or previous failure etc...

the code show here allright, except fact write useless .select can drop .select(m=>m) , leave .tolist there.

further, find out causing crash post exact error message inner exception. (and inner exception's inner exception , on...)

next part "lobj.lobinfoes" repository or something? might post code of , code of data access object well.
