I am a newbie creating an API using C#, encountered error "Severity Code Description Project File Line Suppression State Warning CS0108"

Question

I am encountering this same error on the following fields:

public string txnumber { get; set; }
public string qnumber { get; set; }
public string accountnumber { get; set; }
public decimal amount { get; set; }
public string emailaddress { get; set; }

this is defined in the class Txn.cs.

The error text for all the variables is:

======== here is the Txn.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace QAny.Models
{
    public class Txn
    {
        // define all the proeperties of the table with get and set
        public string txnumber { get; set; }
        public string qnumber { get; set; }
        public string accountnumber { get; set; }
        public decimal amount { get; set; }
        public string emailaddress { get; set; }

    }

    // will create a class to create an object of txn class

    public class createTxn : Txn
    {

    }

    public class ReadTxn : Txn
    {
        public ReadTxn(System.Data.DataRow row)
        {
            txnumber = row["txnumber"].ToString();
            qnumber = row["qnumber"].ToString();
            accountnumber = row["accountnumber"].ToString();
            amount = Convert.ToDecimal(row["amount"]);
            emailaddress = row["emailaddress"].ToString();
        }

        public string txnumber { get; set; }
        public string qnumber { get; set; }
        public string accountnumber { get; set; }
        public decimal amount { get; set; }
        public string emailaddress { get; set; }

    }
}

"hides inherited member", Show the class declaration and the parent class.. Compiler Warning (level 2) CS0108. Note that the compiler tryed to give that information 6 times just in the quoted error message — Drag and Drop
Does this answer your question? Why is a property hiding Inherited function with same name? — Drag and Drop
And Why do I get warning CS0108 about a property hiding a method from a base class? — Drag and Drop

Messages you are seeing indicate that class ReadTxn derives from class Txn which already contains members with the same names.

Those are not errors, just warnings. If you want to suppress them just add new keyword to your property declaration, but remember this also probably means you're doing something wrong because hiding members of a base class is rarely something you actually want to do. To understand this concept better you should read about inheritance in c#. Microsoft docs can be good place to start.
