i'dont find duplicate value... :(

Your `resetPartialHourmeterDictionary` and `resetMainHourmeterDictionary` have duplicated keys. — Zroq, Mar 02 '17 at 14:44
Your sixth and seventh Dictionaries have the key "3" multiple times — pinkfloydx33, Mar 02 '17 at 14:45
but they have two different names of the dictionary, however — Mr. Developer, Mar 02 '17 at 14:45
Use a `Dictionary>` instead. Then you can have such a dictionary: `new Dictionary> { { 0, new List{"NO"} }, { 1, new List{"KEY"} }, { 2, new List{"TR"} }, { 3, new List{"BR","VAC","ALL"} } };` — Tim Schmelter, Mar 02 '17 at 14:47
@Mr.Developer Different variable names don't matter. What matters is that you have a single dictionary and you have the same key specified multiple times. That just won't work. — mason, Mar 02 '17 at 14:47
`but they have two different names of the dictionary, however ` - That's not how dictionaries work, keys must be unique, values don't matter. — Equalsk, Mar 02 '17 at 14:47

you are inserting the Key value 3 multiple times. In a Dictionary each Key must be unique.

public static Dictionary<int, String> resetPartialHourmeterDictionary = new Dictionary<int, String>
    {
        { 0, "NO" },
        { 1, "KEY" },
        { 2, "TR" },
        { 3, "BR" },
        { 3, "VAC" },
        { 3, "ALL" }
    };

In your resetPartialHourmeterDictionary and resetMainHourmeterDictionary, you have same key 3 there.
