var conntion = new SqlConnection (connstring);
Conntion. Open ();
return conntion;
}

List
Public list<user> GetList ()
{
using (idbconnection con = userdal.sqlconn ())
{
String Sqlcommandtex = "SELECT * from Tb_user";
List<user> userlist = Sqlmapper.query<user> (Con, Sqlcommandtex). ToList ();
return userlist;
}
}

Delete
public int del (int id)
{
using (idbconnection con = userdal.sqlconn ())
{
String comm = "Delete from Tb_user where id = @id";

int res = con. Execute (comm, new {id = id});
return res;
}

Parameter list
Public User GetUser (int id)
{

{
String sql = "SELECT * from Tb_user where [email protected]";
User q = con. query<user> (SQL, new {id = id}). Singleordefault ();

Modify
public int UPD (User QQ)
{
using (idbconnection con = userdal.sqlconn ())
{
String sql = "Update tb_user set [email protected],[email protected],[email protected] where [email protected]";
int q = con. Execute (SQL, QQ);
