Attribute is a method of associating additional data to an Attribute (and other constructor), while enumeration is the most commonly used structure in programming, enumeration is essentially a constant value. Compared to using these values directly,

I have been using c # For A While (it was suddenly changed from java). As I am a newbie, I seem to have encountered many problems during the process, now let's think about some strange problems. Maybe we will make the same problem in the future. Now

In a previous C # project, a requirement was to extract the content of Word documents by page. Later, this requirement was unavailable, but some methods were found out from the middle. Currently, this program can be basically used to read .doc).docx

Proxy mode: provides a proxy for other objects to control access to this object.   The Subject class defines the common interfaces of RealSubject and Proxy, so that Proxy can be used wherever RealSubject is used. RealSubject class, which

1. Background When learning C #, we know that using reflection can greatly facilitate our programming (dynamic access to information, call type members, instance creation, etc ), however, there are few opportunities to directly use reflection in

Singleton ensures that a class has only one instance and provides a global access point to it. Generally, we can make a global variable to make an object accessible, but it cannot prevent you from instantiating multiple objects. The best way is to

Double-click a txt file to open it in notepad, because the txt file is associated with the Notepad program. If you want to customize the file type, you can directly call your program and open it by double-clicking it? OK. First, we can find the

= = ==   [EnumDescription( = = ==   Is a self-written class, and the source code will be pasted below. txt = EnumDescription.GetEnumText( txt == EnumDescription.GetFieldTexts( =EnumDescription.GetFieldTexts(= =   Source code [AttributeUsage

    The first thing to do is to build a development environment. Indows 8 not only supports traditional desktop applications, but also introduces a new Metro-style application designed specifically for touch. For Metro applications, it must

Lead: The CPU only recognizes binary code. How does the C # source code become a binary code that can be recognized by the CPU? The procedure is as follows: 1. C # source code 2. Use the Command Prompt window provided by VS to convert the C #

Although app. config is added in C # and access is convenient, sometimes it is not used to it. So let's do a kind of ini configuration file read and write under the C ++ imitation. Others write about calling the unmanaged kernel32.dll. I have also

6. Virtual and non-virtual functions Below is a non-virtual function Plane { TopSpeed() { Jet : Plane { TopSpeed() { Main(= ,plane.TopSpeed()); Because TopSpeed () is a non-virtual function, the above Code will print 300. To solve this

Today I read the example of ajax in head first ajax, which is very good. This book is very good and recommended. Ajax (Asynchronous Javascript and XML) is Asynchronous Javascript and XML, but Javascript and xml cannot be called Ajax. To put it

Due to not a lot of recent work, simple IDE has been simply written; many functions are still being improved. Tools mainly include the SQL designer, Form Designer, and code designer. Interface principle: Use the DesignSurface component of MS to

From the communication in the previous chapter, we found that if Tcp is used to send messages continuously, messages will be sent together, which causes some problems for programming, it may cause some problems for our information parsing. This

In the first round. First, create a department class. Assume that there are only two fields: department ID and department name. ID { ; DeptName { ; The following shows the UML class diagram of the Department table. IDpartment interface,

If you are not clear about bitwise operations, you can read my article, "foundation is the top priority ~ Bitwise calculation and integer variable bitwise calculation (like Enumeration type) What we want to do today is to verify the difference

C # The user seems to want C # to be compiled as a local machine code like C ++. If C # can be compiled as a machine code, it can do as follows: 1. Efficiency improvement can replace C ++. 2. decompilation. Of course, Microsoft is not allowed to do
