I have a very simple web part. I have a single grid view, which I am populating using linq to entities (or at least that's what I want to do). The Entity Data Model .edmx file is located in the same project as the web part, and everything looks to be in working order. When I debug the project, it blows up on the entity model construct...
Suppose I have a Dictionary<String,String>, and I want to produce a string representation of it. The "stone tools" way of doing it would be: private static string DictionaryToString(Dictionary<String,String> hash) { var list = new List<String> (); foreach (var kvp in hash) { list.Add(kvp.Key + ":" + kvp.Value); ...

I don't want to round up. For example, if d is 22.1222222, then...
