Getting Object reference required for the non-static method

Please take note that this is uncompleted code, but just facing some small issue, as i using a lot of c++ OOP concept. i might have some issue when trying to change from another platform.

I get error when compiled and stated nonstatic method/property error 

using System;

public class People
{
    string name;
    int age;
    int height;
    public virtual void insertDetail(People stu)
    {
        Console.Write("Please enter name : ");
        stu.name = Console.ReadLine();
        Console.Write("Please enter age  : ");
        while(!int.TryParse(Console.ReadLine(), out stu.age))
        {
            Console.WriteLine("You enter characters! Please re-insert");
        }
        Console.Write("Please enter height: ");
        while(!int.TryParse(Console.ReadLine(), out stu.height))
        {
            Console.WriteLine("You enter characters! Please re-insert");
        }
    }
}

public class Class : People
{
    static People[] students = new People[5];
    public override void insertDetail(People stu)
    {
        Console.WriteLine("==================================");
        base.insertDetail(stu);
    }


    public static void Main(string[] args)
    {

        for (int i = 0; i < students.Length; i++)
        {
            students[i] = new People();
            insertDetail(students[i]);
        }

        Console.ReadKey();
    }
}

As said in comments, you need an instance to use instance method.

Create an instance for Class inside Main

public class Class : People
{
    static People[] students = new People[5];
    public override void insertDetail(People stu)
    {
        Console.WriteLine("==================================");
        base.insertDetail(stu);
    }


    public static void Main(string[] args)
    {
        Class c = new Class(); // this is required to access insertDetail

        for (int i = 0; i < students.Length; i++)
        {
            students[i] = new People();
            c.insertDetail(students[i]);
        }

        Console.ReadKey();
    }
}

You get that error when you make a static call to an instance method like Object.ToString() using the type name as the qualifier when you really need an instance.

First of all never use Class as your class name. As for the error you need to give more information about what are you trying to do. You have to add static modifier to your method:

public static void insertDetail(People stu)

Or if you want for it to be override than:

public virtual void insertDetail()
{
    this.name = "Some name";
    //...
}
