You may also use Distinct() in System.Linq as in Post# 10 of this thread: http://forums.arcgis.com/threads/16305-Attribute-Query-Task-Question

Do you need the unique values for just one feature or from a given attribute in several features? If you just want the unique values across all attributes in one feature you could do something like this - List values = new List(); foreach (var item in feature.Attributes) { if (!values.Contains(item.Value.ToString())) { values.Add(item.Value.ToString()); } } If you need to get the unique values from a series of features see this forum thread - http://forums.arcgis.com/threads/36312-Attribute-Query-Distinct-values?p=127568#post127568. It's not fast if you have a large number of features to handle but it works. Terry
