I have an SSIS Package that goes out to the web to access a file. The file name will change on a monthly basis and I can derive this and place the values into SSIS Variables.
I found this web site to assist me in creating the pieces to go out to the web and access the file.

And I have created my C# Edit Script accordingly...

#region Help: Using Integration Services variables and parameters in a script
/* To use a variable in this script, first ensure that the variable has been added to
* either the list contained in the ReadOnlyVariables property or the list contained in
* the ReadWriteVariables property of this script task, according to whether or not your
* code needs to write to the variable. To add the variable, save this script, close this instance of
* Visual Studio, and update the ReadOnlyVariables and
* ReadWriteVariables properties in the Script Transformation Editor window.
* To use a parameter in this script, follow the same steps. Parameters are always read-only.
*
* Example of reading from a variable:
* DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
*
* Example of writing to a variable:
* Dts.Variables["User::myStringVariable"].Value = "new value";
*
* Example of reading from a package parameter:
* int batchId = (int) Dts.Variables["$Package::batchId"].Value;
*
* Example of reading from a project parameter:
* int batchId = (int) Dts.Variables["$Project::batchId"].Value;
*
* Example of reading from a sensitive project parameter:
* int batchId = (int) Dts.Variables["$Project::batchId"].GetSensitiveValue();

#region Help: Firing Integration Services events from a script
/* This script task can fire events for logging purposes.

* Example of firing an error event:
* Dts.Events.FireError(18, "Process Values", "Bad value", "", 0);
*
* Example of firing an information event:
* Dts.Events.FireInformation(3, "Process Values", "Processing has started", "", 0, ref fireAgain)
*
* Example of firing a warning event:
* Dts.Events.FireWarning(14, "Process Values", "No values received for input", "", 0);

#region Help: Using Integration Services connection managers in a script
/* Some types of connection managers can be used in this script task. See the topic
* "Working with Connection Managers Programatically" for details.
*
* Example of using an ADO.Net connection manager:
* object rawConnection = Dts.Connections["Sales DB"].AcquireConnection(Dts.Transaction);
* SqlConnection myADONETConnection = (SqlConnection)rawConnection;
* //Use the connection in some code here, then release the connection
* Dts.Connections["Sales DB"].ReleaseConnection(rawConnection);
*
* Example of using a File connection manager
* object rawConnection = Dts.Connections["Prices.zip"].AcquireConnection(Dts.Transaction);
* string filePath = (string)rawConnection;
* //Use the connection in some code here, then release the connection
* Dts.Connections["Prices.zip"].ReleaseConnection(rawConnection);

Because my file name is going to change on a monthly basis, like "FileName_June_2016", I can derive this as a SSIS Variable but then how can I pass this as a variable within my C# Edit Script as a ConnectionString variable?
// Logging start of download
bool fireAgain = true;
Dts.Events.FireInformation(0, "Download File", "Start downloading " + Dts.Connections["HTTP Connection Manager"].ConnectionString, string.Empty, 0, ref fireAgain);
// Get your newly added HTTP Connection Manager
Object mySSISConnection = Dts.Connections["HTTP Connection Manager"].AcquireConnection(null);
// Create a new connection
HttpClientConnection myConnection = new HttpClientConnection(mySSISConnection);Thanks for your review and am hopeful for a reply.
