日期实体类文件和多个模式

Question

场景：
具有多个架构的数据库，例如[DBO]，[S1]，[S2]。

模式可能包含一个与另一个模式中的表同名的表，但它们可能不一定具有相同的定义，因此[dbo]。[table1]可能与[s1]相同或不同[表1]。

我创建了一个生成类文件的应用。例如，这里是为[dbo]生成的类文件。[StudentRemote]进行了一些修改以隐藏一些加密信息：

using System;
using System.ComponentModel.DataAnnotations;
using System.Security.Cryptography;

namespace FlexIT.Model
{
    namespace dbo
    {
        public class StudentRemote
        {
            private Guid _id = Guid.NewGuid();

            public StudentRemote()
            {

            public StudentRemoteController() : base("StudentRemote", "ID", "table", "dbo")
            {
            }
            // Create custom methods here
            // Use "public new" to completely override a method in the generic controller
        }
    }
}

正如您所看到的，我有一个主命名空间 - FlexIT.Model - 和一个＆＃34;子命名空间＆＃34;这是表实体的模式。

因此...

在我调用此实体模型的应用程序中，我执行以下操作。 （此代码查询[dbo]。[StudentRemote]并解密名字。）

您可以在我的使用陈述中看到我尝试做的以及我是如何做的。

我的问题 - 是否有更好的方法来处理同一实体模型中的多个模式？

using System;
using System.Collections.Generic;

using fm=FlexIT.Model;
using fmdbo=FlexIT.Model.dbo;

    class Program

        static public string FlexITKey = "FakeKeyForSecurityPurposes";
        static void Main(string[] args)
        {
            var src = new fm.dbo.StudentRemoteController();
            // or...
            // var src = fmdbo.StudentRemoteController();
            // or, if we were querying [temp].[StudentRemote]...
            // var src = fm.temp.StudentRemoteController();
            // or...
            // var src = fmtemp.StudentRemoteController();
            //
            src.Gets(pKeyname: "ID", pKeyval:new Guid(), pWhere:"or id is not null");

            foreach (var sr in src.InsertRec)
            {
                foreach (var prop in typeof(fm.dbo.StudentRemote).GetProperties())
                {

                    fm.MappingAttribute myMappings = (fm.MappingAttribute)attributes[typeof(fm.MappingAttribute)];
                    if (myMappings.Salt != null)
                    {
                        prop.SetValue(sr, DecryptIt(prop.GetValue(sr, null).ToString(), myMappings.Salt, sr.Salt));
                    }
                }
                Console.WriteLine(sr.FirstName);
            }          
        }

        public static string DecryptIt(string encryptedString, string additionalSalt = "", string recordSalt = "")
        {
            //s=encrypted string
            //e=additional salt
            //h=record salt if needed. This is usually the student's salt value


            CryptoFilterBox mycrypto = new CryptoFilterBox();

            if (String.IsNullOrEmpty(encryptedString) || encryptedString.Trim().Length == 0)
            {
                return encryptedString;
            }
            mycrypto.set_InBuffer(encryptedString.Replace("''", "'"));
            mycrypto.set_Password(FlexITKey + (String.IsNullOrEmpty(recordSalt) ? "" : recordSalt) + additionalSalt);
            mycrypto.Decrypt();
            return mycrypto.OutBuffer;
        }

    }
