Question

I have two dictionaries with a string key and different value types.

private Dictionary<string, IProperty> _properties;
private Dictionary<string, Expectation> _expectations;

I need to compare elements sharing same key and get matching Expectations. Here’s my method signature in Expectation class.

public bool Matches(IProperty property)

How can I do that using LINQ?

Answer 1

var result = _expectations.Where(e => _properties.Any(p => p.Key == e.Key && e.Value.Matches(p.Value)));
