Using .NET 2.0, VS 2005, VB.net

I have a connection object (global scope) and other objects that I want to remove from memory when finished. I call Close, then Dispose then set it to nothing. Is this a good way to clear up the object or is this too much. Also, I call the garbage collector after all of this.

Thanks
San


myOleDbConnection.Close()
myOleDbConnection.Dispose()
myOleDbConnection = Nothing
 
GC.Collect()

Close() will be enough, Dispose() will call close anyway.
If you plan to use the connection variable again, then use Nothing, if not, then it is not needed.
GC.Collect() will not collect when you want, the .net environment will decide the proper time.

Thanks Jaime_Olivares,

Then what's the purpose of anyone calling GC.Collect() if the garbage collector is going to run on its own time?

GC.Collect() is not commonly used, there are several discussions about that in Intenet you can google.
