Although we don't need to focus on memory management and garbage collection in the. NET Framework, we need to be aware of this in our minds for the purpose of improving the performance of our applications. Understanding the basic behavior of memory

The principle is actually very simple, take out two time difference seconds, and then between 0 to the second number of random to get an integer, to add it to the smaller times, it can be said that there is no technical difficulties in the

The garbage collector behaves well in memory management, and it removes objects that are no longer in use in a very efficient way. But no matter how you look at it, it takes more processor time to apply and release a heap-based object than to

A simple fact:. NET applications are running in a managed environment, and this environment has a lot of conflict with different designers, and that's effective C #. A great deal of discussion about the benefits of this environment requires changing

This is the only principle in this book that is occupied by an entire function, and you should avoid writing such a function. GetHashCode () is used only in one case: that is, the object is used for keywords based on the hash set, such as the

Also in the DOS era, people are looking for a multitasking implementation. Then there is a TSR type of background-resident program, more representative of the side Kick, Vsafe and other excellent TSR procedures, the emergence and application of such

First, the preface Looking at the 5th edition of C++primer recently, previously read the 4th edition, but found that the 5th version of the entire knowledge layout and the interpretation of individual knowledge with the 4th version of the

Inheritance (inheritance) and dynamic binding are an important component of object-oriented, that is, inheritance (inheritance) and polymorphism (polymorphism), You can make a derived class (derived class) an interface (interface) that has a base

In the inheritance process, you need to distinguish between copy and virtual copy (virtual copy); When a derived class is converted to a base class, it is possible for copy (copy) to cut out the derived part of the derived object (sliced down),

Class template (class template) friend and common class friends, there are many differences, The main reason is that the class template contains template parameters (template parameter), which causes the friends and class templates to have many

Write the program, you need to write data in the folder, if the folder does not exist, you can not write, at the program entrance needs to be judged; Two solutions to Windows because they belong to the system layer. Reference: Http://stackoverflow.

File transfer The examples used in the previous two articles are transmission strings, and sometimes we might want to pass files between the server and the client. For example, consider a situation where the client displays a menu that sends files

When an expression contains multiple operators, the precedence of the operator controls the order in which a single operator is evaluated. For example, an expression x+y*z is evaluated by x+ (Y*Z) because the "*" operator has a higher priority than

To use C # to manipulate word, you first add a reference: 1, add Reference->com->microsoft Word 11.0 Object Library 2, in the. cs file add Using Word; The following examples include C # 's creation of Word documents, inserting tables, setting

I. Environmental preparedness In this article, all programs are developed under Linux and tested to work properly. In the development process, we need to use gSOAP, can be downloaded from the following Web site: http://www.cs.fsu.edu/~engelen/soap.

C # How to achieve multiple inheritance, the key is the interface can write the implementation of the method Namespace Extensions{Using System;Using ExtensionMethodsDemo1; public static Class Extension{Extended interfacepublic static void MethodB (

The best programmers will make mistakes in programming, not to mention those of us beginners; good programmers will find bugs and modify them. Sometimes there are some subtle bugs in the program that we have to track code to debug when we can't find

. NET since 2.0, has greatly improved the function of mail.smtpclient, for the e-mail, can be very comfortable. However, the drawback is not to provide the ability to save the content of the message as a EML file In fact, SmtpClient and MailMessage
