SSIS using ADO connection manager for Script Component

This post is to show how to use ADO connection in SSIS Script Component. At the same time, this is what myself always forget.
Bear in mind, I never successfully using OLEDB connection for this. I only successfully using this with ADO.NET connection.
Before going into the Script Editor make sure you create a Connection Manager for your Script Component.

Open your Script Editor in Script Component (inside the Data Flow normally) by double clicking in. In the root area outside any method, I declared the following.
IDTSConnectionManager100 ConMgr;
object Targetconnection;

In between PreExecute and PostExecute methods, insert the follow AcquireConnections method. Sure there are other way to do this.

public override void AcquireConnections( object Transaction)
{
ConMgr = this .Connections.ConnectionBlock;
Targetconnection = this .Connections.ConnectionBlock.AcquireConnection( null );
SqlConn = Targetconnection as SqlConnection ;
}

You do not need to SqlConn.Open() to open the connection if you are utilizing the Connection Manager.
