How does asp.net use the anti-injection login authentication program for ODP, that is, oracle connections?
This article introduces the knowledge of "asp.net how to use ODP, that is, the anti-injection login authentication program of oracle connection". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
The copy code is as follows:
/ / user login check

Bool result = false
/ / regular expression check
If (Regex.IsMatch (fanciLoginName @ "^ [a-zA-Z0-9] {1Magne15} $") & & Regex.IsMatch (falloff LoginPassgy @ "^ [a-zA-Z0-9] {1jce15} $"))
{
OracleConnection objConn = new OracleConnection (ConfigurationManager.ConnectionStrings ["ConnectionString"] .ConnectionString)
OracleCommand objCmd = new OracleCommand ("select * from USERS where username=:pUserName and password=:pPassWord", objConn)
ObjCmd.Parameters.Add ("pUserName", OracleDbType.Varchar2). Value = f_LoginName
ObjCmd.Parameters.Add ("pPassWord", OracleDbType.Varchar2). Value = f_LoginPass
ObjConn.Open ()
OracleDataReader objDr = objCmd.ExecuteReader ()
/ / read the content
If (objDr.Read ())
{
Result = true
}
/ / close the database
ObjDr.Close ()
ObjConn.Close ()
}
Return result
}
