I have tried this on IDE SharpDevelop not on visual studio.
I am using the namespace like this:
using System.Data.OleDb;
But it is showing me following error:
'Data' does not exist in the namespace 'System'(are you missing an assembly reference?)(CS0234)
Listen to the compiler: you’re probably missing a reference to the
System.Dataassembly in your project. You need to add that reference using theAdd Reference...dialog from theProjectmenu.
