Get SharePoint list data that instantiated workflow?

Question

So I'm creating a SharePoint 2010 project in Visual Studio that contains a Sequential Workflow (Farm Solution only) item that is associated with a certain list so that when an item is added to the list the workflow starts.

My question is, say an item was added in the following format:

Name | Email

Dave | [email protected]

Is there a way, programatically, to store this data in variables? As is, without using any hardcoded indexes or anything, just programatically have it so that I can pull this data and store it in two C# variables (int iD, string emailAddress) and the workflow knows which list item kicked it off?

At the moment the way I'm doing it is:

using (SPWeb oWeb = SPContext.Current.Web) {
    SPList oList = web["List Name"];
    string name = list.Items[(oList.ItemCount - 1)]["Name"].ToString();
}

But I'd rather not use indexers as there's a chance that the index is off if another item is added rapidly and if the list is reordered then ... disaster.

Thanks in advance!

Solved it guys! Very stupid of me to overlook this, but here is the solution:

C# creates a workflowProperties variable for you of type SPWorkflowActivationProperties which contains all the methods and properties to get the data you need:

public SPWorkflowActivationProperties workflowProperties = new SPWorkflowActivationProperties(); // auto generated code.

Then to get the list item data or even list data all you do is:

SPList oList = workflowProperties.List; // get the list that contains the list item on which the workflow instance is running.
SPListItem oItem = workflowProperties.Item; // get the list item on which the workflow instance is running.

So to get my "Name" data I would've had to:

string name = workflowProperties.Item["Name"].ToString();

Hope this helps someone, although fortunately nobody is as stupid as me so you guys will probably figure it out yourself.
