Question

我在oracle中有一个表，包含不同的用户名，密码，尝试，同意，管理和锁定日期。用户名和密码是输入参数，其他的是输出参数。如果数据库中的用户名和密码存在，我必须返回登录状态Y否则N. 另外我需要获得outstarmeter的值，例如，tryss，agree，admin等。当我在oracle中执行存储过程时，输出很好，我无法在C＃中填充它。这是我的代码。我正在使用asp.net的登录控件（login.aspx）

 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
 {

     string username = Server.HtmlEncode(Login1.UserName);
     string pwd = HttpUtility.HtmlEncode(Login1.Password)

     var isUserValid = userbll.ValidateUser(username, pwd, out userInfo);
     //calling function to bll.

Userinfo是一个单独的类，包含所有属性（name，pwd，attempt，agree，admin等），我将userinfo作为out参数传递

userBLL.css

public bool ValidateUser(string username, string password, out UserInfo userInfo)

    {
       string vLoginStatus=dataClass.ValidateUser(username, password, out userInfo);

       if (vLoginStatus == "Y")
       {
           return true;
       }
       return false;

DLL代码

internal string ValidateUser(string username, string password, out UserInfo userInfo)

    {
        OracleParameter[] p = 
        {
            OracleHelper.MakeInParam("in_username", OracleDbType.Varchar2, 20, username),
            OracleHelper.MakeInParam("in_password", OracleDbType.Varchar2, 32, password),
            OracleHelper.MakeOutParam("out_Login_ok", OracleDbType.Varchar2, 1),

            OracleHelper.MakeOutParam("out_admin", OracleDbType.Varchar2, 1),
            OracleHelper.MakeOutParam("out_agree", OracleDbType.Varchar2, 1),

            OracleHelper.MakeOutParam("out_type", OracleDbType.Varchar2, 2),
            OracleHelper.MakeOutParam("out_locked", OracleDbType.Varchar2, 1),

            OracleHelper.MakeOutParam("out_errornumber", OracleDbType.Int32, 0)
        };

        OracleHelper.ExecuteNonQuery(OraClientConnectionString,
               CommandType.StoredProcedure,
          string.Format("{0}.{1}.{2}", Schema, PackageName, "stored proc Name"), p);


         var vLoginStatus = ((OracleParameter)p[2]).Value.ToString();
        userInfo = new UserInfo
        {
            Username = username,
            Password = password,

            Admin = ((OracleParameter)p[3]).Value.ToString(),
            Agree = HrOracleHelper.ConvertToBoolean(((OracleParameter)p[4]).Value.ToString()), // hrhelper is just a class to change agree and locekd to boolean

            Locked = HrOracleHelper.ConvertToBoolean(((OracleParameter)p[5]).Value.ToString()),
            F
        };
        var errorNumber = ((OracleParameter)p[6]).Value.ToString();
        if (Convert.ToInt32(errorNumber) != 0)
        {
            //Nlog.logerror
            return "N";
        }
        return vLoginStatus;

我的问题是关于已验证用户的数据库登录状态是Y，但是我没有得到它，而且我没有在c＃中获得任何outout参数值。如何在c＃中获取数据库输出参数值？

无法将参数值从oracle返回到c＃
