Contructor is inaccessible due to its protection level

Question

my error is:

Error 1 'aCI.CheckTexture.CheckTexture()' is inaccessible due to its protection level

and i use this code to check some files MD5/Hash :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

namespace aCI
{
class CheckTexture
{   
    Thread Search;
    protected CheckTexture()
    {
        Search = new Thread(Scan);
        Search.Start();
    }

    protected void Scan()
    {
        if (GetMD5Hash("1.rar") != "9647997C556C5A37A63EFAFBCA4A40D0"
           || GetMD5Hash("2.rar") != "6626959A9099B4C6F5C755E0D2E57EF8"
           || GetMD5Hash("3.rar") != "4D6611A825F81024E0153E2753B8A27E")
        {
            System.Windows.Forms.MessageBox.Show(
            "Sorry come back and restor your orginal files.",
            "Error",
            System.Windows.Forms.MessageBoxButtons.OK,
            System.Windows.Forms.MessageBoxIcon.Error);
            return;
        }
    }

}

Then i try Using class CheckTexture from the above code in here:

 private void BtnMpLanClick(object sender, RoutedEventArgs e)
    {
        if (!File.Exists("chrome.exe"))
        {
            MessageBox.Show("Cannot find chrome.exe");
            return;
        }

        else
        {
            //Process.Start("chrome.exe");
            this.StartTheProcess("chrome.exe", "");

            Thread.Sleep(10);

            try
            {
                // I have error on this line:

                CheckTexture Scan = new CheckTexture();

            }
            catch (Exception)

            { }

        }

    }

but I have that error on this line:

CheckTexture Scan = new CheckTexture();

SO pleas if possible someone tel me what is my mistake. Thank you for help

Answer 1

The class isn't public. Change it to:

public class CheckTexture
{   
    Thread Search;
    public CheckTexture()
    {
        Search = new Thread(Scan);
        Search.Start();
    }
