In the C, C + +, and D programming languages, Const is a type qualifier, a keyword applied to a data type that indicates tha t the data is constant (does not vary). While this can is used to declare constants, const in the C family of languages

In the C + + programming language, a reference is a simple reference datatype that's less powerful but safer than the point ER type inherited from C. The name C + + reference may cause confusion, as in computer science a reference are a general

This morning I reviewed some of the commonly used classes in the C # language that I learned yesterday: the String class, the math class, and the DateTime class.Several representative exercises have been done:1. Get the current time and add n days

If the namespace is longer and is used frequently in programs, you can use using to set the namespace alias, and C # introduces an alias mechanism to shorten programmer development time such as:Using Nsserialize = System.ComponentModel. Design.

9.7 Structure TypeThe 8th chapter mentions that structs and classes are very similar, but structs are value types , and classes are reference types . What does that mean? The most concise way is to use an example to illustrate. The code is as

The keyword partial is a contextual keyword that only has the meaning of the keyword when it is put together with class, struct, interface. Therefore, the introduction of partial does not affect variables with the name partial in the existing code.

In C # There are probably two kinds of data types: value types and reference types, which need to be determined by the developer of the defined type where to assign an instance.Value types and reference types differ in principle, and value types are
