Regarding mulitple rows insert in one shot using ADO .net connected to postgres

Hi ,

I want to insert multiple Rows in one shot to improve my performance .

From C# code I am using ADO .net to connect to postgres .
Currently i am pasting the code which is not of postgres but in my dev environment similar things  i am doing with Postgres.

MySqlConnection mySql = new MySqlConnection();
        mySql.CreateConn();
        mySql.Command = mySql.Connection.CreateCommand();
        mySql.Command.CommandText = "INSERT INTO dbo.table1 (textBox1, textBox2) VALUES (@textBox1, @textBox2)";
        
        mySql.Command.Parameters.Add("@textBox1", SqlDbType.VarChar);
        mySql.Command.Parameters["@textBox1"].Value = TextBox1.Text;
        mySql.Command.Parameters.Add("@textBox2", SqlDbType.VarChar);
        mySql.Command.Parameters["@textBox2"].Value = TextBox2.Text;

        mySql.Command.ExecuteNonQuery();             
 
        mySql.Command.Dispose();
        mySql.Connection.Close();
        mySql.CloseConn();


Hi i have hilighted the line in  which I wanted to ask doubts .

Currently i am inserting one row in one time and then executing the query .
So with this approach i need to execute it many times for multiple rows insert because of this my database is poor in doing this each time for very large data.

What i want here is to insert multiple rows and then executing it in one time only so that it will be faster.

Please help me out in this regards .
