Environment is vistual studio 2019 and.net. Core 3.0 practice encapsulation and attributes in the console application environment don't know how to write the set with constraints, the original program can perform as follows


The namespace ConsoleApp2
{
Public class Student
{
Private int _AGE;

Public int the AGE
{the get=& gt; _AGE; The set=& gt; _AGE=value; }




The namespace ConsoleApp2
{
Class Program
{
The static void Main (string [] args)
{
Student student=new Student();
Student. AGE=18;//set the attribute values, so that the object of the Age value of 18
Console. WriteLine ($" xiao Ming's AGE is {student. AGE} ");//get the student. The Age attribute value
The Console. ReadKey ();

}
}
}
