Testing UI select using Protractor.Net based on index?

Question

I am testing the UI select using Protractor.NET. I had referred the following link for testing the UI select - Testing with protractor using ui-select

My problem which I am running into is that the data from the list item varies. So I can't hard code the value.

Is there a way to test the UI select based on an index so that whatever the items, I can send an index value as 0 which would satisfy my requirements.

Edited: Included the code

       var getCountry = NgDriver
           .FindElement(NgBy.Model("vm.Country"))
           .FindElement(By.ClassName("ui-select-container"));

        getCountry.Click();

        var selectedCountryItem = getCountry.FindElement(By.ClassName("ui-select-search"));
        selectedCountryItem.SendKeys("Iran");
        selectedCountryItem.SendKeys(Keys.Enter);

The above code works perfectly as I have hard coded to Iran. I need to send an index instead of this hard coded value.

Thanks in advance.
