Visual Anonymous Method Basics The anonymous method is a new language feature of the c#2.0. The main content of this article is to provide readers with a better understanding of the internal implementation and working methods of anonymous methods. This article is not intended to be a complete language attribute reference for anonymous methods. Anonymous method

extension methods enable you to "add" methods to an existing type without creating a new derived type, recompiling, or otherwise modifying the original type. an extension method is a special static method, but it can be called just like an instance method on an extended type. for client code written in C # and Visual

Introduction: I feel like I haven't updated my blog for a long time. The anonymous method will be introduced in this topic. The anonymous method can also be understood by name, of courseMethod without name(In real life, there are also many such anonymous processes, such as anonymous voting and anonymous reporting. I believe Microsoft will certainly follow the examples in life in terms of naming ), however,

) { ... } } The constructor uses two new operators to establish two delegate instances. Implicit method group conversions allow them to be written in a shorter form: Public Alertdialog () { Okbutton.click + = Okclick; Cancelbutton.click + = Cancelclick; ... } As with other implicit and explicit conversions, conversion operators can be used explicitly in a particular transformation. Therefore, the following example: Object obj = new EventHandler (M

After the Objective-c object receives the message, what method is called to be resolved during runtime. Then you might ask: Does the method corresponding to the given selection sub-name change at runtime? Yes, that's it. Using this feature can be a huge advantage because we do not need the source code or the ability to override the class itself by inheriting subc

same time, the dinosaur successfully Imitated All the behavior of the duck and was mistakenly treated as a duck for release, causing program crash.PythonThe exception handling mechanism is simply a "magino line of defense", which has benefited us. You can't blame the dinosaurs for deliberate disruption. The Sb method is defined elsewhere, but its fck method is defined for you. you mistakenly think of it as

= typeof (icustomformatter )) Return new customerformatprovider (); Return NULL; } # Endregion // A nested class that provides a custom format for the customer class. Private class customerformatprovider: icustomformatter { # Region icustomformatter members Public string format (string format, object Arg, Iformatprovider formatprovider) { Customer c = Arg as customer; If (C = NULL) Return Arg. tostring ();

change after the call is completed. In fact, we can clearly see the meaning of the two from the name-the pass-through parameter transfers a copy of the call parameter, while the transfer parameter passes the memory address of the call parameter, this parameter points to the same storage location inside and outside the method. Note that the ref modifier must be added to the method call of the address passin

cases produces the same effect given the same argument. This rule allows the following code optimizations. Delegate double Function (double x); class test{static double[] Apply (double[] A, Function f) {double[] result = new double[ a.length];for (int i = 0; i }Because two anonymous method delegates have the same set of captured external variables (both empty) and because the anonymous method is semantica
