Is it possible to have a generic constraint which is an unbounded generic type?
For example:
public T DoSomething<T>(T dictionary) where T : IDictionary<,>
{
...
}
Edit: Just to explain the context, I want to constrain the usage of the method to an IDictionary, but for the method itself it does not matter exactly what TKey and TValue are.
这是不可能的,您需要指定类型参数:
public T DoSomething<T, TKey, TValue>(T dictionary) where T : IDictionary<TKey, TValue> { ... }
There is an issue in rosylin github , however, it's not done yet. So it's not possible right now, but I expect it will be relatively soon.
No, you can't do that. Maybe you can use
public IDictionary<TKey, TValue> DoSomething<TKey, TValue>(IDictionary<TKey, TValue> dictionary)
{
...
}
