Most efficient way to insert Rows into MySQL Database

I've read a lot of questions about that but i couldn't find one that is fast enough. I think there are better ways to insert a lot of rows into a MySQL Database

I use the following code to insert 100k into my MySQL-Database:

public static void CSVToMySQL()
{
    string ConnectionString = "server=192.168.1xxx";
    string Command = "INSERT INTO User (FirstName, LastName ) VALUES (@FirstName, @LastName);";
    using (MySqlConnection mConnection = new MySqlConnection(ConnectionString))
    {
        mConnection.Open();

        for(int i =0;i< 100000;i++) //inserting 100k items
        using (MySqlCommand myCmd = new MySqlCommand(Command, mConnection))
        {
            myCmd.CommandType = CommandType.Text;
            myCmd.Parameters.AddWithValue("@FirstName", "test");
            myCmd.Parameters.AddWithValue("@LastName", "test");
            myCmd.ExecuteNonQuery();
        }
    }
}

This takes for 100k rows about 40 seconds. How can i make this faster or a little more efficient?

Might be faster to insert multiple rows via a DataTable/DataAdapter or at once:

INSERT INTO User (Fn, Ln) VALUES (@Fn1, @Ln1), (@Fn2, @Ln2)...

Due to security issues i can't load the data into a file and MySQLBulkLoad it.
