How to Create Setup file for .NET Windows application?

public Form1()
{
    InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
   //Below code is used to uninstall application
   
   //Get Command Line Arguments
   string[] arguments = Environment.GetCommandLineArgs();            
   foreach (string argument in arguments)
   {
       if (argument.Split('=')[0].ToLower() == "/u")
       {
           string guid = argument.Split('=')[1];
           string path = Environment.GetFolderPath(Environment.SpecialFolder.System);
           ProcessStartInfo si = new ProcessStartInfo(path + "\\msiexec.exe", "/i " + guid);
           Process.Start(si);
           Close();
           Application.Exit();
           System.Environment.Exit(0);
       }
   }   

   //Load DataGridView first time when form load
   refreshGrid();        
}

void refreshGrid()
{
    string query;
    con.Open();
    if(textBox1.Text=="")
    {
        query="select eno,empname,sal from emp";
    }
    else
    {
        query = "Select eno,empname,sal from emp where empname like '%" + textBox1.Text + "%'";
    }
    cmd=new OleDbCommand(query,con);
    da = new OleDbDataAdapter(cmd);
    dt.Clear();
    da.Fill(dt);
    dataGridView1.DataSource = dt;
    con.Close();
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
    //Refresh grid values when each text entered in textbox by user.
    refreshGrid();
}           
}
