1. type conversion:
Type conversion includes display conversion and implicit conversion. The basic rules for type conversion in. NET are as follows:Any type can be safely converted to its base class type, which can be completed by implicit

1. attribute is always used to replace accessible data members.
2. readonly 3 is preferred between readonly and Const. the as operator is preferred between AS and forced type conversion. use conditional attributes instead of Conditional
1. IntroductionType security is one of the key considerations at the beginning of the. NET design. For program designers, it is often unable to fully grasp the type security of system data. Now, all this has been solved for you in the design
primitive types for programming languagesSome data types are so common that many compilers allow code to manipulate them in simplified syntax. System.Int32 a = new System.Int32 (); A = 0a = 1; Equivalent to: int a = 1; this syntax not only enhances
About C #C # is one of the few languages that reach the Microsoft Common Language Runtime (CLR). Achieving the CLR's language can benefit from the features it brings, such as cross-language integration, exception handling, security enhancements, a
Boxing and unpacking are the actions that are performed to convert between value types and reference types.1. boxing occurs when a value type is converted to a reference type2. unpacking occurs when a reference type is converted to a value typeThe
Benefits of Generics:1. You can guarantee type safety and avoid boxing and unboxing, and generic classes will be replaced by specific types at compile-time.2. Let's take a ArrayList to say, ArrayList to do the unpacking operation, that is, ArrayList
4. Box packing and unpackingBoxing and unpacking are important concepts in C #. It allows any type of data to be converted to an object, while allowing any type of object to be converted to a compatible data type. Boxing: is to convert any data
1, assigning a value type to a reference type becomes boxed. Object obj= 10; 2, assigns the reference type to the value type for the unboxing operation. an int a = (int) Obj;3,is operator that checks whether an object is a type and returns a bool
Generics are a feature of programming languages. Allows programmers to write in strongly typed programming languagesThe code defines some mutable parts that must be specified before they are used. The various programming languages and their
, boxing and unpacking is an abstract concept 2, boxing is theValue types are converted toobject type is converted to each other, and the value type is linked to the reference type for example: int val =, Object obj = val; Console.WriteLine ("Value
In this paper, a simple example of the implementation of C # Boxing and unboxing operations, simple boxing is to convert a value type to a reference type, unboxing is to convert the reference type to a value type, is involved in the use of stacks
When you use a series of strings (strings) in C # code and need to create a list for them, the,list generic class is a very good solution for storing a series of strings (strings). Here are some examples of list generic classes, let's take a look at
Numeric type of 1.ScalaScala's numeric types are similar to Java's, and their scope is consistent with Java. Unlike Java, they are objects and are instances of the corresponding numeric classes. Scala provides powerful support for these numeric
