Question

Is there a way to get intellisense for all the keys in a Dictionary<string,string> in C#?

Or is it possible to get intellisense for a method with a string parameter.

I want to have something like ResourceManager.GetString("") has. and if possible i don’t want to create a static class with constant strings to simulate it.

Edit:

I am currently using a dictionary to combine multiple resource files in to one dictionary, this is done becouse resources are used in multiple projects and need to be overwriten.

var temp = ResourceFile1.ResourceManager
                    .GetResourceSet(CultureInfo.CurrentUICulture, true, true)
                    .Cast<object>()
                    .Select(
                        x => new
                            {
                                ID = 1,
                                Value = x.GetType().GetProperty("Value").GetValue(x, null).ToString(),
                                Key = x.GetType().GetProperty("Key").GetValue(x, null).ToString()
                            });
                temp = temp.Concat(
                    ResourceFile2.ResourceManager
                        .GetResourceSet(CultureInfo.CurrentUICulture, true, true)
                        .Cast<object>()
                        .Select(
                            x => new
                            {
                                ID = 2,
                                Value = x.GetType().GetProperty("Value").GetValue(x, null).ToString(),
                                Key = x.GetType().GetProperty("Key").GetValue(x, null).ToString()
                            }));
                temp = temp.Concat(
                    ResourceFile3.ResourceManager
                        .GetResourceSet(CultureInfo.CurrentUICulture, true, true)
                        .Cast<object>()
                        .Select(
                            x => new
                                {
                                    ID = 3,
                                    Value = x.GetType().GetProperty("Value").GetValue(x, null).ToString(),
                                    Key = x.GetType().GetProperty("Key").GetValue(x, null).ToString()
                                }));
            ResourceDictionary = temp.GroupBy(x => x.Key)
                .Select(x => x.FirstOrDefault(c => c.ID == x.Max(v => v.ID)))
                .ToDictionary(x => x.Key, x => x.Value);

Answer 1

Don’t use string, but an enum in this case, if you know the finite values.

By definition, string can contains any value at run-time, while enums are known at compile time.

Or you can simply avoid the use of a dictionary. If you know that your dictionary will contains always the same keys, you should better create a class with one property per key you previously used.
