StreamReading StreamWriting Using SSIS Script Task

How many times you need to stream reading from a file and writing into another well here it is...Here we are using special character char(30) and char(31) as delimited so a quick replace using regex did it. It's Simple,Quick, and Dirty :-)
Enjoy.

The execution engine calls this method when the task executes.
To access the object model, use the Dts property. Connections, variables, events,
and logging features are available as members of the Dts property as shown in the following examples.

To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
To post a log entry, call Dts.Log("This is my log text", 999, null);
To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);

To use the connections collection use something like the following:
ConnectionManager cm = Dts.Connections.Add("OLEDB");
cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";

Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.

To open Help, press F1.
