Expose only the required actions on the dictionary as methods in the interface, not the dictionary (-property).

do you mean have the Interface declare method signatures for such actions as Dictionary ... 'Add, 'Remove, etc. ?

Or, could you mean ... in the Interface ... declare the signature of a method whose "only purpose" is to set the initial Value of the Property ?

I, for one, look forward to the upcoming provision in future versions of C# of method constraints: that's been mentioned in something I read recently (mabye Eric Lippert's blog ?), but I locate find the source right now.

you must, of course, implement those Properties the Interface specifies as 'Public ... that's the way Interfaces work in C# / .NET.

The second part is more architectural. It sounds to me like the problem you are trying to solve is most likely one that indicates that you aren't separating concerns. In other words, you are mixing the behaviour of the interface with the form.

[Browsable(false)]

public Dictionary<int, string> IntToString {

this.someComponent1.IntToString = ((System.Collections.Generic.Dictionary<int, string>)(resources.GetObject("someComponent1.IntToString")));
