Solved Compiler Error CS0050 (C#) (1 Viewer)

[silentwolf]

Hi guys,

I am running into a problem in C# and hope someone could let me know how I would need to change following Code.

incosistent accessability: return type List<Person> GetPeople is less accessable then method 'DataAccess'.GetPeople.

This is a code Tim Corey did profide on a You Tube Tutorial. Unfortunatelly I get the Error but can't seam to work out where I would need to change the accessibility.

So maybe someone could tell me please?

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Dapper;

namespace SonnenhausCSharpAndSQLServer
{
  public class DataAccess
  {
    public List<Person> GetPeople(string lastName)
    {
      using (IDbConnection connection = new System.Data.SqlClient.SqlConnection(Helper.CnnVal("Sonnehaus")))
      {
        var output = connection.Query<Person>($"SELECT * FROM Employees WHERE SurName = '{ lastName}'").ToList();
        return output;
      }
    }
  }
}

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SonnenhausCSharpAndSQLServer
{
  public partial class Dashboard : Form
  {
    List<Person> people = new List<Person>();

    public Dashboard()
    {
      InitializeComponent();
      UpdateBinding();
    }

    private void UpdateBinding()
    {
      peopleFoundListbox.DataSource = people;
      peopleFoundListbox.DisplayMember = "FullInfo";
    }

    private void searchButton_Click(object sender, EventArgs e)
    {
      DataAccess db = new DataAccess();
      people = db.GetPeople(lastNameText.Text);
      UpdateBinding();
    }
  }
}

Many thanks

I noticed you have yet to receive a reply to your question. I'm not surprised, because I doubt if there's many people here that have experience with the c sharp language, but you never know! Hence I am bumping it up the list so that it gets another look. Best of luck.

That's hard because the code you quoted shows only part of the problem.
Here is a hint:
Look at your definition of the Person class. I guess, you defined the class as private or protected, but you use it (indirectly) as return type of your public GetPeople method. - This cannot work because callers of GetPeople may receive a type they don't know anything about.

Hi guys,

sorry was not here but yes I did manage to get it to work!
@sonic8,
Yes that was the issue the Class was not defined as public but did not spot it at first.

Many thanks for replies and hints!
Cheers
