Delegation is a new term in C # and is widely used. For example, events are the simplest and most direct examples of delegation.First, let's talk about delegation. In fact, delegation is a function pointer to people who have used C or C ++, but most

C # viewing Stacks is usually in exception handling. When an exception occurs, you can easily get this error through the stack.CodeCall path. This is useful. Can I use this method to troubleshoot non-exception errors when no exceptions occur? The

1. Dynamic expandoobjectAnyone familiar with JS knows that JS can be written like this: VaR T = new object (); T. ABC = 'something'; T. value = 243; We can also use this JS Dynamic Language Feature in C #, provided that a variable is declared as

// Obtain the complete path of the current process, including the file name (process name ). String STR = This. getType (). assembly. location; Result: X: \ XXX \ xxx.exe (.exefile directory. .exe file name) // obtain the complete path of the new

I believe many people have encountered a problem:CodeToo many objects. I don't know where to modify this object. There are actually two ways. 1. When debugging, you can set a data breakpoint. GDB has a watch breakpoint. for example, GDB> watch *

C # multithreading: Principle of volatile keywords from: blog garden font size: [large, small] Abstract:The volatile keyword is only used for class or structure fields. It is used to notify the compiler that multiple threads will access this

If a double-type value is not a number, it can be expressed in. net. DoubleD =Double. Nan; The prototype of double. Nan is as follows: //// Summary:// Represents a value that is not a number (NAN). This field is constant.Public const

Producer and consumer issues are always classic issues. Simply making multiple threads compete, occupying resources and then processing them will make the complexity of the system quite complex, and it is difficult to control the concurrency of

For native C ++ development in Windows Mobile and Windows WinCE (Windows Embedded CE), you sometimes need to retrieve the path of the current execution file or call the path information of the module, for example, the configuration file and local

C # process-related sorting 1. Obtain the user name of a process based on the process name? You need to add a reference to system. Management. dll. Using System. diagnostics; Using System. Management; Static Void Main ( String [] ARGs ){

1. When creating a new object, CLR will create its type object at the same time (if the object type object does not exist). The type object includes static fields and methods. 2. The memory allocated to objects in the heap includes instance fields,

Icloneable sounds like a good idea: icloneable interfaces can be implemented for those types that support replication. If you do not want to support replication, do not implement it. But our type is not in the vacuum. Setting a type to support the

I believe some of my friends have also met such an interview question. I will try to answer this question. 1. Allocate objects to the stack Therefore, objects must be prohibited from being allocated on the stack. A simple method is to privatize

Struct definition: # Include "stdafx. H "// memory alignment 1 byte # pragma pack (1) struct day {int datetime; int open; int high; int low; int close ;## Pragma pack () Pointer reading: // Test. CPP: defines the entry point for the console

When creating a binary component, it also means that you need to use late binding and reflection to find what you need with Special FunctionsCode. Reflection is a powerful tool that allows you to write software that can be dynamically configured.

User input may be diverse: You must verify the input as much as possible in interactive controls. Writing user input verification may be tricky, and there may also be errors, but it is still necessary. You cannot trust your input too much. The user

. NET provides interfaces, which are different from class or struct type definitions. In some cases, the interface seems to be the same as the abstract class, so some people think that the. NET interface can be used to replace the abstract class

The classes in many. Net class libraries provide two different methods for processing event handles. You can add an event to it or override the event abstraction method of its base class. Why do we provide two different methods for the same thing?
