Using arrays inside a custom data object (WPF C#)

Question

Assume I have a custom data object names MyDataObject, defined as such:

    public class MyDataObject
{
    public string Caption { get; set; }
    public int inx { get; set; }
    public string[] inputArr = new string[6];
}

I now can add MyDataObject to a list of objects. As shown below:

public void PopuList()
    {

        var items = new ObservableCollection<MyDataObject>();
        items.Add(new MyDataObject() { Caption = "foo", Checked = false, inx = 0 });
        listBox.ItemsSource = items;
    }

The problem I am having is that I cannot seem to add an array (inputArr as seen in the code above) to MyDataObject. inputArr is to have a length of 6, of which will be customized for each item. Some elements will be left blank. My attempt at getting arrays to add to the MyDataObject is as follows:

items.Add(new MyDataObject() { Caption = "foo", Checked = false, inx = 0, inputArr[0] = "bar" });

For some reason this gives me an error across the entire inputArr[0] = "bar". The error states The name inputArr does not exist in the current context.

I have also tried

items.Add(new MyDataObject() { Caption = "foo", Checked = false, inx = 0, inputArr = { "a","b","c","d","e","f" } });

This however gives me an error on each of the six strings. The error is: string[] does not contain a definition for 'add'

Any clues on adding arrays to custom data objects?

new MyDataObject() { Caption = "foo", Checked = false, inx = 0, inputArr = new string[] { "a","b","c","d","e","f" } }; but if you make inputArr a List<string>, your code will work. it will be simpler to transform list inputArrinto a property too — ASh

Arrays are so DotNet Framework 1.1'ish. I'd suggest using IList<string> or ICollection<string> — granadaCoder

You can use an array initializer:

items.Add(new MyDataObject() 
{ 
    Caption = "foo", 
    Checked = false, 
    inx = 0, 
    inputArr = new [] { "a","b","c","d","e","f" } 
});

Note

In the definition of MyDataObject, I don't see a property whose name is Checked. If this isn't a property of MyDataObject, you have to remove it from the above object initializer.
