Although calling stored procedures is not difficult to implement, reasonable code organization in the program can make the program structure clearer and easier to maintain. The following example divides the calling of a stored procedure into three

I. Definitions of text files and binary files As we all know, computers are physically stored in binary. Therefore, the difference between a text file and a binary file is not physical, but logical. The two are only different at the encoding level.

There are indeed many existing encryption and decryption classes using the. NET Framework. To be more flexible and secure, you can convert string to Char and then encrypt and decrypt it using your own method. Using system;Using system.

We know that for some basic data types (int32, long, double, etc.) We can perform some operations through +,-, *, but for some of the complicated types defined by ourselves, if we want to implement these functions, we can only define some methods to
