LINQ to the rescue!

var list = new List<string>
{
    "Red",
    "Blue",
    "Green",
    "Red",
    "Red",
    "Green"
};
var indexes = Enumerable.Range(0, list.Count).Where(i => list == "Red").ToList(); // {0, 3, 4}

Aditionally, if you need just one value, use

myAbils.IndexOf("string to find"); //returns -1 if not found
