This article mainly explains "how to understand the C# data type". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to understand the C# data type".

The main differences are:

The ◆ constant declares that Java uses the final keyword for this purpose, while C # uses the keyword const or readonly.

◆ compound C # data type: in Java, we can use class keywords to create a compound C # data type as a class without methods, but C # provides struct for this, just like in C.

◆ destructor: C # allows us to create destructor methods that are called before destroying an instance of the class. In Java, you can provide a finalize () method to include code that clears resources before the object is garbage collected. In C #, this function is provided by a class destructor. A destructor is similar to a constructor that has no arguments and is preceded by the wave character "~".

◆ function pointers: C # provides a construct called delegate to create type-safe function pointers. Java does not have any equivalent mechanism.

C # data type

C # provides all the data types available in Java and adds support for unsigned numbers and new 128-bit high-precision floating-point types.

In Java, for each basic data type, the core class library provides a wrapper class to represent it as a Java object. For example, the Integer class wraps the int data type, while the Double class wraps the double data type.

In C #, all basic data types are objects in the System namespace. For each C# data type, an abbreviation or alias is provided. For example, int is short for System.Int32, while double is short for System.Double. Because C# represents all basic data types as objects, it is possible to call object methods according to the basic C# data type. For example:

Int iTunes 10; Console.WriteLine (i.ToString ()); thank you for reading, the above is the content of "how to understand the C# data type". After the study of this article, I believe you have a deeper understanding of how to understand the C# data type, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
