using System;
public class Program
{
public static void Main()
CloudCollectionHelper cloudHelper = new CloudCollectionHelper();
SlackHelper slackHelper = new SlackHelper();
cloudHelper.DatabaseID=12345;
Console.WriteLine(slackHelper.GetSlackPageTokens());
}
class CloudCollectionHelper
{
public long DatabaseID { get; set; }
}
class SlackHelper:CloudCollectionHelper
{
public long GetSlackPageTokens()
{
return DatabaseID;
}
}
}

current output: 0 Expected Output: 12345

I need output 12345 because DatabaseID from the cloudhelper so i need that databaseID in the slackhelper.

this is my c# online compiler: https://dotnetfiddle.net/QNQeEX

I dont want to write something below because I have 1000+ field in the cloudhelper

SlackHelper slackHelper = new SlackHelper();
slackHelper.DatabaseID=12345;
Console.WriteLine(slackHelper.GetSlackPageTokens());

Thanks in advance.

Hi Talaviya,
Try this code:
class Vehicle  // base class (parent)
{
  public string brand = "Ford";  // Vehicle field
  public void honk()             // Vehicle method
  {
    Console.WriteLine("Tuut, tuut!");
  }
}

class Car : Vehicle  // derived class (child)
{
  public string modelName = "Mustang";  // Car field
}

class Program
{
  static void Main(string[] args)
  {
    // Create a myCar object
    Car myCar = new Car();

    // Call the honk() method (From the Vehicle class) on the myCar object
    myCar.honk();

    // Display the value of the brand field (from the Vehicle class) and the value of the modelName from the Car class
    Console.WriteLine(myCar.brand + " " + myCar.modelName);
  }
}

your code should be like below
public static void Main()
       {


           SlackHelper sh = new SlackHelper();

           Console.WriteLine(sh.GetSlackPageTokens());
           Console.ReadLine();
       }


public  class CloudCollectionHelper
   {
       public  long DatabaseID { get; set; }
   }
public  class SlackHelper:CloudCollectionHelper
   {

       public long GetSlackPageTokens()
       {
           DatabaseID = 12345;
           return DatabaseID;
       }
   }
