perform iteration in StringTemplate4 (C#)

Question

In the StringTemplate4 cheat sheet ( http://www.antlr.org/wiki/display/ST/StringTemplate+cheat+sheet ), it mentions that to perform an iteration

<attribute:{anonymous-template}>
Apply an anonymous template to each element of attribute. The iterated `it` attribute is set automatically.

I have tried the below code:

        List<TextParseTests.TestModel> data = new List<TextParseTests.TestModel>();
        for (int i = 0; i < 10; i++)
        {
            TextParseTests.TestModel model2 = new TextParseTests.TestModel();
            model2.Name = i.ToString();
            data.Add(model2);
        }


        string template = @"TestTemplate|| <List:{ [DataList <it.Name>]  }> [END]";

        Template t = new Template(template);
        t.Add("List", data.ToArray());


        var result = t.Render();
        sb.AppendLine(result);

Update 1

Below are the TestModel data structure and related classes. I am using these just

    public class ContactDetailsTest
    {
        public string Email { get; set; }
        public string Address1 { get; set; }
    }

    public class TestModel
    {
        public string Name { get; set; }
        public string Surname { get; set; }
        public ContactDetailsTest ContactDetails { get; set; }

        public TestModel()
        {
            this.ContactDetails = new ContactDetailsTest();
        }
    }

Yet the end result is:

"TestTemplate||  [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [DataList ]   [END]"

It does get iterated 10 times, however the variable it does not seem to have been populated. Any ideas?

You need to change your template to this

TestTemplate|| <List:{x | [DataList <x.Name>]  }> [END]

As of this documentation

<attribute:{x | anonymous-template}>
Apply an anonymous template to each element of attribute.  
The iterated value is set to argument x. 
The anonymous template references <x> to access the iterator value.

You can set x to anything you like, it's just a place holder for the iterator.

The problem was that you were using the StringTemplate3 cheatsheet instead of the StringTemplate4 cheatsheet http://www.antlr.org/wiki/display/ST4/StringTemplate+cheat+sheet
