WebMar 26, 2013 · Both methods are found. Type inference is applied to both methods without validating the constraints - so for the first method, we get T = Foo and for the second method we get T = Bar. Both methods are applicable at this point. Overload resolution is performed, which decides that the first method is the most specific one.

WebJul 7, 2011 · Since C# 8.0, as you can see here, it is now possible to define local methods in interfaces and implement them within the interface itself, e.g. allowing to create method overloads without requiring implementations to care about those overloads as well, when they might just supply an additional parameter to the overload that has to be implemented. WebAug 3, 2015 · 6. You have two different methods. public String methodA (String a, int b, String c, long d) {} and. public String methodA (int e, String f, String g) {} that represent two different contracts to childA and childB respectively. You cannot define an interface with a single methodA that fits both definitions. dyson dc65 animal complete attachments

It sounds like you want value equality, and that means you want to force them to override the .Equals () (and consequently also .GetHashCode ()) functions.
