Where are you stuck ? Despite being weird, it's kind of trivial. You need to iterate over your buttons and compare their names to the strings you have in your array.

public static void create_button()
{
for (int i = 0; i < arrlist.Count; i++)
{
string value = arrlist[i] as string;
value.visible=true
}
MessageBox.Show(value);
}

now over here value and button name are same and i want to set visible like this

OK, so you have no idea how to program at all ? I suggest you read a beginner book if you don't know how to compare two values.

It might help,

I assume all the Buttons have been created in design time,

C#

namespace ButtonsVisibilityTest
{
    using System;
    using System.Collections;
    using System.Windows.Forms;
    public partial class frmMain : Form
    {
        private ArrayList visibilityControlList = new ArrayList() { "AAA", "BBB", "CCC" };
        public frmMain()
        {
            InitializeComponent();
        }

        private void frmMain_Load(object sender, EventArgs e)
        {
            AAA.Visible = GetVisibilityStatus(AAA.Text);
            BBB.Visible = GetVisibilityStatus(BBB.Text);
            CCC.Visible = GetVisibilityStatus(CCC.Text);
            DDD.Visible = GetVisibilityStatus(DDD.Text);
            EEE.Visible = GetVisibilityStatus(EEE.Text);
            FFF.Visible = GetVisibilityStatus(FFF.Text);
        }
        private bool GetVisibilityStatus(string buttonName)
        {
            return visibilityControlList.Contains(buttonName);
        }
    }
}
