在本系列教程中,我们以一个大型CMS系统的完整开发流程为例,和大家一起探讨net开发的经验和教训。在本程序中,我们采用了流行的三层/N层框架+仓储模式的架构模式。项目分层示意图:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Data; using System.Data.SqlClient; namespace EasyFast.Repository.Interface { public interface IRepository<T> where T : class { T GetById(int id); T Find(string where, string orderColumn, List<SqlParameter> parameters); int Add(T model); int Delete(int id); int Update(T model); int GetPageCount(string tableName, string where, List<SqlParameter> parameters); DataTable GetPageList(string tableName, string fieldNames, string where, string orderColumn, int startRecordIndex, int endRecordIndex, List<SqlParameter> parameters); DataTable GetDataTable(string tableName, string fieldNames, string where, string orderColumn, List<SqlParameter> parameters); } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using EasyFast.Repository.Interface; using System.Data; using System.Data.SqlClient; namespace EasyFast.Repository { public class Repository<T> : IRepository<T> where T : class { public T GetById(int id) { T model = default(T); return model; } public T Find(string where, string orderColumn, List<SqlParameter> parameters) { T model = default(T); return model; } public int Add(T model) { int _result = 0; return _result; } public int Delete(int id) { int _result = 0; return _result; } public int Update(T model) { int _result = 0; return _result; } public int GetPageCount(string tableName, string where, List<SqlParameter> parameters) { int _result = 0; return _result; } public DataTable GetPageList(string tableName, string fieldNames, string where, string orderColumn, int startRecordIndex, int endRecordIndex, List<SqlParameter> parameters) { DataTable dt = new DataTable(); return dt; } public DataTable GetDataTable(string tableName, string fieldNames, string where, string orderColumn, List<SqlParameter> parameters) { DataTable dt = new DataTable(); return dt; } } }
