ProviderBase

ProviderBase<Key, Value> is base class for providers. It implements most the IProvider features, such as properties, indexer and different TryGet variants.

IProvider<double, double> squareProvider = new SquareProvider();
WriteLine(squareProvider[10]); // -> "100"

Implementing class overrides TryGetValue method.

public class SquareProvider : ProviderBase<double, double>
{
    public override bool TryGetValue(double x, out double value)
    {
        value = x * x;
        return true;
    }
}
