Casting C# out parameters?

Question

Is it possible to cast out param arguments in C#? I have:

Dictionary dict;  // but I know all values are strings
string key, value;
         


        

Answer 1

No, there is no way around that. The out parameter must have a variable that matches exactly.

Using a string reference is not safe, as the dictionary can contain other things than strings. However if you had a dictionary of strings and tried to use an object variable in the TryGetValue call, that won't work either even though that would be safe. The variable type has to match exactly.
