Writing this seriesArticleBefore that, I had to declare one thing, that is, from the very beginning we started to use. Net in our ownProgramAnd Excel, such as reading data display reports from Excel and exporting data from the program to excel. This

First, you must be familiar with file and folder operations in. net. File and directory are the two most important classes. Understanding them will greatly facilitate the implementation of subsequent functions.This section briefly introduces two.

Monitor object 1. monitor. the enter (object) method is to obtain the lock, monitor. the exit (object) method is to release the lock, which is the two most commonly used methods of monitor. Of course, to avoid the lock being released due to

C # differs greatly from Java in understanding the static keyword, mainly in the internal class. In addition, because JAVA does not have a data structure similar to delegate, internal classes must take important responsibilities such as

The constructor initialization list starts with a colon, followed by a list of data members separated by commas (,). Each data member is followed by an initialization formula in parentheses. For example: Class Cexample { Public : Int A;

In C ++, the database status is very high. Mr. Bjarne stroustrup, father of C ++, has repeatedly said that designing libraries to Expand functions is better than designing more syntaxes. In reality, C ++ has a wide variety of database categories and

Any data which is declaredPrivateInside a class is not accessible from outside the class. A function which is not a member or an external class can never access such privateData. But there may be some cases, where a programmer will need access to

When dealing with the amount, it is usually necessary to output an upper-case form of the amount, which is a traditional Chinese Style. Hey hey, it also improves security. There are many ways to write RMB in upper case. Today, I provide one for
