What is expansion? Extended stored procedures allow you to use external routines such as C to create your own. For users, the extended stored procedure and common stored procedure have the same execution method. Parameters can be passed to the

Last time I tested the function call speed evaluation for classes and struct (http://www.cnblogs.com/zyl910/archive/2011/09/19/2186623.html) and sealing classes (http://www.cnblogs.com/zyl910/archive/2011/09/20/2186622.html) respectively. Now we

Ah_bill has a lot of knowledge about Java, while C # has a look at it only because of work needs. C # is very similar to Java in syntax, at first, I was confused about delegation and events. I believe that most beginners have similar confusions.

When I was writing a program, I always felt that a field could meet the requirements. Why should I use attributes that are difficult to define?To define get and set, the Code volume is large and I really don't know their differences and

Sometimes we want to save the class instance for future use. An intuitive method is to write the class as one line, separate each attribute with \ t, and then read it with streamreader. However, this is too troublesome. There are many lines of code,

First, we need to know whether the program memory has been leaked, and then find out which line of code has been leaked in order to fix it. Of course, the simplest method is to use professional detection tools, such as boundscheck, which is very
