Check out example codes for "c# class constructor". It will help you in understanding the concepts better.

Code Example 1

public class Person
{
   private string last;
   private string first;

   public Person(string lastName, string firstName)
   {
      last = lastName;
      first = firstName;
   }

   // Remaining implementation of Person class.
}

Code Example 2

//The Class
public class MyClass
{
  	//Some Variables
	public readonly int var1;
  	public readonly string var2;
  	//readonly only lets you set it ina constructor	
  
  	//The Constructor (public [class name](parameters))
  	public MyClass(int param1, string param2)
    {
      	//Setting the earlier variables
     	var1 = param1;
      	var2 = param2;
    }
}

//Creating an object using that class
MyClass Class1 = new MyClass(10, "Hello, World!");
MyClass Class2 = new MyClass(9999, "This is the second object!");

Console.WriteLine(Class1.var1);
Console.WriteLine(Class2.var2);

//Output
//10
//This is the second object!
