As a php development engineer, to improve the technology, you must have a deeper understanding of C. PHP engineers are most exposed to the Apache server, so today they will be trained first. For more information,
The default initialization process of the. NET system sets all objects to 0. We will inevitably create a value type initialized to 0, so we should use 0 as the default value of the type to avoid unnecessary bugs.
1. Set 0 to the enumerated valid

We know that all static member variables of this type should be initialized before a type instance is created in C. The C # language provides a static initiator and a static constructor. Where,A static constructor is a special constructor. It will
# Include " Stdio. h " # Define N 5 Void Main (){ Int A [ 5 ], Num, I = 0 , J, temp; While (I N) {printf ( " Enter 1 ~ Number of 9 " ); Scanf ( " % D " ,& Num ); If (Num> 9 | Num 0 ) {Printf ( " Incorrect input range \ n " );
Drag a datagridview control in winform and an openfiledialog control. The function of this example is to read an Excel file. I am still studying other functions.

Multi-thread support for Attributes
Attributes are implemented through methods, so natural attributes also have all the language features of the method (abstract, interface, virtual ...)
Attribute allows
In C #, callback is implemented through delegation. The delegate provides us with a secure callback definition. Most delegates are related to events, but this is not all application scenarios of the Delegate. When classes need to communicate, in

To ensure that the type can complete its work, we should allocate the minimum access level to the type as much as possible. The lower the visibility, the less changes you need to upgrade and change later-because you can access your functionCodeThe

Recently, I am working on the dsoframer control. I plan to build a custom control to encapsulate this COM component. There are many twists and turns in the middle. After studying it for a week, I finally finished it.
The following is a summary of
# Include # Include # Define Maxlength 1000 Typedef Struct { Int Total; Int Date [maxlength];} linelist; Void Showlist (linelist * List ){ Int I; If (List-> total =0 ) {Printf ( " Empty linear table \ n " ); Return ;} Printf ( "
Persistence is an important feature of type. As long as our type is not a UI control, form, or form, we should add serialization support for the type as much as possible .. Net serialization is to save all member variables in the class to the output
