1. Delegate invoke and begininvoke1.1. Delegate. InvokeDelegate. Invoke is used to execute a delegate on the current thread. We know that the delegate is a reference to a function or method, and delegate. Invoke is the call Use methods or functions. 1.2. Delegate. begininvokeDelegate. begininvoke is used to asynchronously execute a delegate and execute it in a

access a non-static variable, you cannot call a non-static method directly, you need to instantiate an object, and then use that object to access the non-static variable or non-static method to invoke. In other words, a static method cannot directly use a non-static member. Personal understanding is that non-static members are dependent on the object, when there is no instance of an object, non-static members are not allocated memory space, static me

Use reflection to dynamically create instances and Invoke methods . NET is a powerful feature of its ability to access the application's metadata through a process called reflection (reflection). Simply put, reflection is the ability to query type information at run time. The. NET Reflection API is actually a set of classes defined in the System.Reflection namespace. These classes enable you to view accessories and type information in a logical way.

The key issue is their intrinsic connection. Although you can look at the source code, including the class library. But to abstract them out helps to understand. In the customer class (that is, the client class for the following code), statement manager managerproxy=(Manager) Proxy.newproxyinstance (Managerimpl.getclass (). getClassLoader (), Managerimpl.getclass (). GetInterfaces (), Securityhandler); As you can see, the Newproxyinstance method in the proxy (library Class) is invoked, which r

When developing alexseo software today, it appears that you cannot call invoke or begininvoke on the control before creating a window handle.

to the two features of a product, which can be easily implemented if there is a need for contact between the two, such as communication. For the C # language, there are three ways to achieve the interoperability of managed and unmanaged code. 1. Platform Invoke Service 2. C + + Interoperability 3. COM Interoperability The following first describes the platform invoke service: Platform

The invoke thread waits for the dispatcher to call the specified method, and then proceeds to the following operation.BeginInvoke do not have to wait for dispatcher to invoke the method of formulation, proceed directly to the following operation.From: Baidu knowsThis is a common way to manipulate UI controls in a thread so that the program works better and has a better user experience. The following example

InvokeRequired, Invoke, invokerequired In multi-threaded applications, different threads are involved in accessing the same control.# Prohibit cross-thread direct access to the control.When a control is created, it records who created it, that is, its creation thread. If you call the control from another thread, you must use the Invoke method of the control to mail the call to the thread that calls the cont

backgroundDuring the project, sometimes you need to invoke DLL files that are not written in C #, especially when using some third-party communication components, when developing applications through C #, you need to use the DllImport feature to make method calls. This article will guide you through the process of making this call fast.Steps1. Create a csharpinvokecpp solution:2. Create a C + + Dynamic Library project:3. In the application settings, s

The Invoke () method is a delegate mechanism for Unity3dsuch as: Invoke ("a", 5); It means: Call the A () method after 5 seconds;There are 3 points to note when using the Invoke () method:1: It should be called in the life cycle of the script (Start, Update, Ongui, Fixedupdate, lateupdate);2:invoke (); Cannot accept me

CURL (clients for URL) is a common command line tool used to transmit data based on URLs. It supports HTTP, HTTPS, FTP, and other protocols. In fact, on Windows, a similar command Invoke-WebRequest has been added since Powershell 3.0. The following Help information is displayed when you execute Get-Help Invoke-WebRequest. Take a look at the ALIASES section. The curl is in the column. That is to say, you can
