Before the. net Framework was put forward, writing components was regarded as a kind of work that requires advanced skills, which made many people daunting. The emergence of. net makes component compilation so approachable. The core language C # Of.

Like Java, C # provides a rich set of class libraries, methods, and events for developers to use. C # also introduces GDI +, which evolved from GDI, which has more powerful functions than GDI and simplifies programming for programmers. Therefore,

1. (int) is a type conversion. It can be implicitly converted from int type to long, float, double, decimal type. Explicit conversions are required from the long type to the int type. Otherwise, compilation errors may occur.2. int. Parse () is a

The second section of metamorphosis provides extensions for if/else, swith/case, and while. The comments vary and I feel a little far-fetched. One of the examples is a Swith extended application. Today, we suddenly have a new idea and made some
