Add value to list item depending on another list item value

Question

I am using this code to populate a list in C# with data from a Web Api that gets data from a csv file

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync("http://localhost:12345/api/items");

var info = new List<SampleDataGroup>();

if (response.IsSuccessStatusCode)
{
    var content = await response.Content.ReadAsStringAsync();

    var item = JsonConvert.DeserializeObject<dynamic>(content);

    foreach (var data in item)
    {
        var infoSect = new SampleDataGroup
        (
            (string)data.Id.ToString(),
            (string)data.Name,
            (string)"",
            (string)data.PhotoUrl,
            (string)data.Description
        );
        info.Add(infoSect);
    }
}
else
{
    MessageDialog dlg = new MessageDialog("Error");
    await dlg.ShowAsync();
}

I would like to assign a photo to (string)data.PhotoUrl, depending on its Name.

For example: If the Name is "Car", I would like it to be assigned the PhotoUrl "Assets/Images/car.jpg". If an item in the lists Name is "Boat", assign it's PhotoUrl to "Assets/Images/boat.jpg".

The Images are not included of the CSV file that the web api feeds on.

There will be more than one item in the list with the same Name, but all with the same Name will share the same assigned image.

How do I do this?

what's stopping you using `if else condition`? `if(data.Name == "Car") { display car pic ...Assets/Images/car.jpg } else if .....` — Nick Kahn, Nov 12 '13 at 02:25
Would that be the best way? Then there would be about 15 statements. — Tester, Nov 12 '13 at 02:35
can you not use string.Format? `url = new Uri(string.Format("...Assets/Images/{0}.jpg",data.Name));` — Trae Moore, Nov 12 '13 at 03:01

What is info in new info? Is it some class of yours? If yes, does it inherit from the SampleDataGroup type you typed your list with? If yes and you are assigning values to it using a constructor, then use

data.PhotoUrl = string.Format("Assets/Images/{0}.jpg", data.Name)

Doing this with if/else as mentioned in comments would be a suicide. IF not now, then surely when you decide to expand.

Sorry, I made a mistake above. `info` should be `SampleDataGroup`. See the edit above. `SampleDataGroup` is a structure defined in my data model of my application. – Tester Nov 12 '13 at 11:11
@Tester All right. Does my answer solve your problem or do you need something else? – Ondrej Janacek Nov 12 '13 at 11:13
