      hi pathmakumara,

      U have added Npgsql.dll only so, this type of errors occured.
      u have to add mono.security.d ll.

      follow this,
      steps, right click, Add refference,
      goto npsql folder, it included three folders, like doc,Mono,MS1.1

      now click the MS1.1 folder It has two .dll - like Mono.Security.d ll,Npgsql
      You Must add both DLL then run it'll work perfectly.

          Thanks a lot to who reply me

          But the problem with me now is where should I download the folder. Because I download from this link

          http://pgfoundry.org/frs/?group_id=10001 40&release_id=9 58

          it contains only three files with Npgsql.dll.

          Thanks

              hello pathmakumara, u don't downloaded the dll.

              you have to add the dll in your "Bin folder" in ur appln. right click Bin folder,
              select Add refference and then click the browse button, where you have installed your Postgresql . i think it will be installed C drive. in the C drive program files,
              PostgreSQL, and then it has subfolder like 8.1, click this It has folder like Npgsql , click Npgsql It has three folder U click the M.S1.1, This folder contain Two .DLL . U Must Select Both DLL and Add ur Bin folder. Now run it ... Don't Downloaded these dll Because already having both dll in ur npgsql.

              regards,
              Bangalore Guys...
              and

                  thanks so much

                  But I am using Postgresql version 8.3 and Installation notes says that Npgsql is not in a directory and Npgsql is installed int Global assembly cash. But I couldn't still overcome the problem. If there is idea, tell me. Thanks again
