Array

Question

I want to create an array contains variables in different class like this codes:

internal class Students
{
public string Stdname;
int Credit_hours;
int id;
string dept;
Course []courses;
string DateOfBirth;
public Students(string name, int id ,string DateOfBirth,Course[]courses) {
this.Stdname = name;
this.id = id;
this.DateOfBirth = DateOfBirth;
this.courses = courses;
}

public void print(Course[] courses, Func<Course, bool> filter, params int[] courseIDs)
{
Console.WriteLine("|name: "+Stdname+"|ID: "+id+"|The Date Of Birth"+ DateOfBirth +"|Courses:" );
foreach (Course course in courses)
{
if (filter(course) && courseIDs.Contains(course.CourseId))
{
Console.WriteLine("|Course ID: " + course.CourseId + "|Course Name: " + course.CourseName);
}
}
}
}

Answer 1

in c# arrays contain homogeneous elements;

inside the class give all the visibility, otherwise those are private by default. and try to use PascalCase.

note: if you don't know how many elements will you use maximally, then don't use arrays, use list instead....

internal class Students {
private Students() {
this.Students = new List<Students>();
// load it from file (csv), for the first time
}

public List<Students> Students;
// and use properties (getters and setters)
}
