Database operations using C # Class | Ebubekir Bastama

Good day, friend.

In this article, I will show you the automatic sql connection with class with C #.
At first we add a class to our project and we create a method that returns "SQLConnection".

        public SqlConnection connection()
            if (con.State == ConnectionState.Closed)
            return con;


If the state of the connection is closed, we open the state of the connection. Now let's show how we use it.

  public void kolonverigetirme(string sqlcumle)
            SqlCommand kmt = new SqlCommand(sqlcumle,connection());
            var s= kmt.ExecuteScalar();
            rowcount = int.Parse(s.ToString());           

In this example, we wrote a method to use the class again, and we got the number of columns and a global variable. But as you can see, we did not say "con.open".
The only thing we do is "connection ()". Our connection was automatically turned on, as shown.
