如何将HTML代码从编辑器插入MySQL数据库？

MySqlConnection con = new MySqlConnection(@\"Connection String  \");//I\'ve tested the connection string and its working fine

MySqlCommand cmd = new MySqlCommand(\"INSERT INTO ins (tes) VALUES (\'\" + Editor1.Content + \"\')\", con);

con.Open();
cmd.ExecuteNonQuery();
con.Close();

MySqlCommand cmd = new MySqlCommand(\"INSERT INTO ins (tes) VALUES (\'\" + Editor1.Content.Replace(\"\'\", \"\'\'\") + \"\')\", con);
con.Open();
cmd.ExecuteNonQuery();
con.Close();

tes

MySqlCommand cmd = new MySqlCommand(\"INSERT INTO ins (tes) VALUES (@text)\", con);

cmd.Parameters.Add(\"@text\", SqlDbType.Text);
cmd.Parameters[\"@text\"].Value = txtTextField.Text;

con.Open();
cmd.ExecuteNonQuery();
con.Close();
