Dictionary<string, Dictionary<string, string>> MyDict =
new Dictionary<string, Dictionary<string, string>>();

Now I realised, that I would need in some cases some other (not dictionary-like) data as value of the main dict.

] | You can do that. After retrieving data from the main dictionary, you will have to cast the result to an appropriate type:
```
object obj;
If(mainDict.TryGetValue("key", out obj)) {
var dict = obj as Dictionary<string, string>>;
if (dict != null) {
// work with dict
} else {
var value = obj ... | Well, your code will be less typesafe and you will need runtime type checks and type casts, but otherwise you can use `object` as a dictionary value type and store any types there. |

] | By using object as the value in your dictionary you will incur some risk and complications:
* Lack of type safety (anything can be set to the value)
* You would have to cast to a particular type, probably based on the value
You should probably rethink your design. But if you really want a the flexibility you could cr... | No, there's no problem. If you need to type the value as `Dictionary<string, string>` just cast it and you'll have this solved. |
