1.simply Exec Sqlstr:
public void DoSql()
{
SqlOperator.oSqlConnStr=@"password=noneed;user id=albert;data source=218.5.74.183;initial catalog=Albert"//<----Define default Connection string for this Appliction ，one Appliction only need define .in one place.

using(SqlOperator myOperator=new SqlStr("select * from Test"))
{
myOperator.Exec();
}
}

1.simply Exec SPr:
public void DoSqlSP()
{
SqlOperator.oSqlConnStr=@"password=noneed;user id=albert;data source=218.5.74.183;initial catalog=Albert"//<----Define default Connection string for this Appliction

using(SqlOperator myOperator=new SqlSP("SP Name"))
{
myOperator.AddP("ParameterName",Value)
myOperator.AddP("ParameterName2",Value)
myOperator.AddP("ParameterName3",Value)
myOperator.Exec();
