I have some queries (to an acccess database) like this :

string comando = "SELECT * FROM ANAGRAFICA WHERE E_MAIL='" + user + "' AND PASSWORD_AZIENDA='" + password + "'";

推荐答案

您需要使用的参数。好了不要有，但将是preferable。

You need to use parameters. Well dont have to but would be preferable.

SqlParameter[] myparm = new SqlParameter[2];
myparm[0] = new SqlParameter("@User",user);
myparm[1] = new SqlParameter("@Pass",password);

string comando = "SELECT * FROM ANAGRAFICA WHERE E_MAIL=@User AND PASSWORD_AZIENDA=@Pass";
