Как вызвать статический метод в обработчике событий?

static class DbMethod
{
static void Connect(System.Data.Common.DbConnection sqlConnection1)
{
var connectionString = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;
sqlConnection1.ConnectionString = connectionString;
try
{
sqlConnection1.Open();
if (sqlConnection1.State == System.Data.ConnectionState.Open)
{
MessageBox.Show("Подключение открыто");
}
}
catch (Exception)
{
if (sqlConnection1.State != System.Data.ConnectionState.Open)
{
MessageBox.Show("Невозможно открыть подключение");
}
}
finally
{
if (sqlConnection1.State == System.Data.ConnectionState.Open)
{
sqlConnection1.Close();
}
sqlConnection1.Dispose();
}
 
}
}

private void button1_Click(object sender, EventArgs e)
{
DbMethod.Connect;
}

using System;
using System.Data.SqlClient;
 
namespace ConsoleApplication37
{
    class Program
    {
        static void Main(string[] args)
        {
            using (SqlConnection conn=new SqlConnection("Data Source=(localdb)\\MSSQLLocalDB;Integrated Security=true; Initial Catalog=usersdb"))
            {
                conn.Open();
                SqlCommand command = new SqlCommand("Select * from users", conn);
                SqlDataReader dr= command.ExecuteReader();
 
                while (dr.Read())
                {
                    Console.WriteLine(dr[0]);
                    Console.WriteLine(dr[1]);
                }
                dr.Close();
            }
        }
    }
}

private void button1_Click(object sender, EventArgs e)
{
DbMethod.Connect(sqlConnection1)
}

private void button1_Click(object sender, EventArgs e)
{
SqlConnection sqlConnection1 = new SqlConnection;
DbMethod.Connect(sqlConnection1);
}
