Question

well i am working for PocketPc and it has a library (System.data) and
(System.data.sqlclient) then THEY are not complete libraries then i need use
System.data (the complete library) but now i have 2 dll’s calls (System.data)
and the complete library has System.data.sqlclient too, then i have problem with them, so
if i only use the complete library i have another problem, cuz the System.data( no complete library) has one thing wich System.data(Complete library) doesn’t have, so i need use 2 dlls (with same namespace) and i have problems…

See extern alias in MSDN and a tutorial to use them in visual studio.

From the command line compiler the references are declared as :

/r:SystDataOfficial=System.Data.dll
/r:SystDataOther=data.dll

Then in your code :

extern alias SystDataOfficial;
extern alias SystDataOther;

var c = new SystDataOfficial::System.Data.SqlClient();

You could also put only one of the dlls as an alias and use the other one normally

Please note that the types won’t be usable together. This code won’t work :

// Expect SystDataOfficial::SomeConstant
SystDataOfficial::System.Data.SqlClient.SomeMethod(SystDataOther::SomeConstant);
