Spark view engine with array of namevaluepair

Question

I would like to use the Spark view engine (DirectUse) for email templating. So I have dived into the Spark examples (EmailOrTextTemplating). But what I want is to use an array of NameValuePair(String name, object value) objects in the viewdata as a dictionary.

And then use this in the template like this:

<p>Name = ${#namevaluepairs["name"]}</p>

or

<if condition='namevaluepairs["date"].ToString("dd-MM-yyyy") == "31-01-2013"'>
  <p>text</p>
</if>

I don't know what the correct syntax is or how to put the namevaluepairs in the viewdata. Can anyone help me in the right direction?

Ps I read the documentation but I see different ways of using the spark engine syntax.

Answer 1

The ViewData object is a dictionary.

Just load your objects into ViewData before calling Spark:

var engine = new SparkViewEngine();
var descriptor = new SparkViewDescriptor()
            .AddTemplate( templateFileName );
ISparkEngineView view = engine.CreateInstance( descriptor ) as ISparkEngineView;

view.ViewData["name"] = "foo";
view.ViewData["date"] = DateTime.Now;

view.RenderView( writer );

then in the template use ViewData like you normally would:

${ViewData["name"]}

<if condition='ViewData["date"]...'></if>
