A factory method is a method that … You can use System.Delegate or System.MulticastDelegate as a base class constraint. The CLR always allowed this constraint, but the C# language disallowed it. The System.Delegateconstraint enables you to write code that works with delegates in a type-safe manner. The following code defines an extension … See more Constraints specify the capabilities and expectations of a type parameter. Declaring those constraints means you can use the operations and method calls of the constraining … See more The use of a generic type parameter as a constraint is useful when a member function with its own type parameter has to constrain that … See more You can apply constraints to multiple parameters, and multiple constraints to a single parameter, as shown in the following example: See more Type parameters that have no constraints, such as T in public class SampleClass{}, are called unbounded type parameters. Unbounded type parameters have the … See more
