NHibernate Demo 和 效率测试

本文关于NHibernate的Demo和效率测试，希望对大家有用.

1.先去官网下载Nhibernate

2.放入到项目中并建立Helper类

  private static ISession _Session = null;
 
         public static ISession Session
         {
             get
             {
                 if (_Session == null)
                 {
 
                     Configuration cfg = new Configuration();
 
                     // _Session session factory from configuration object
                     _Session = cfg.Configure(CurrentLocation + "Nhibernate.config").BuildSessionFactory().OpenSession();
                 }
 
                 return _Session;
             }
         }

写操作方法

更新

 public static string SaveOrUpdate<T>(T item)
         {
             Helper.Session.Clear();
             string msg = string.Empty;
             try
             {
                 using (Helper.Session.BeginTransaction())
                 {
                     Helper.Session.SaveOrUpdate(item);
                     Helper.Session.Transaction.Commit();
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
 
             return msg;
         }

 public static string Save<T>(T item)
         {
             Helper.Session.Clear();
             string msg = string.Empty;
             try
             {
                 using (Helper.Session.BeginTransaction())
                 {
                     Helper.Session.Save(item);
                     Helper.Session.Transaction.Commit();
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
 
             return msg;
         }

 public static string Update<T>(T item)
         {
             Helper.Session.Clear();
             string msg = string.Empty;
             try
             {
                 using (Helper.Session.BeginTransaction())
                 {
                     Helper.Session.Update(item);
                     Helper.Session.Transaction.Commit();
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
 
             return msg;
         }

 public static string Delete<T>(T item)
         {
             Helper.Session.Clear();
             string msg = string.Empty;
             try
             {
                 using (Helper.Session.BeginTransaction())
                 {
                     Helper.Session.Delete(item);
                     Helper.Session.Transaction.Commit();
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
 
             return msg;
         }

 public static string Delete<T>(List<T> itemsToDelete)
         {
             Helper.Session.Clear();
             string msg = string.Empty;
             try
             {
                 using (Helper.Session.BeginTransaction())
                 {
                     foreach (T item in itemsToDelete)
                     {
                         Helper.Session.Delete(item);
                     }
                     Helper.Session.Transaction.Commit();
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
 
             return msg;
         }

Delete

 public static IList<T> GetEntityList<T>(IList<ICriterion> whereCondition)
         {
             return GetEntityList<T>(whereCondition, null);
         }

获取数据实体列表

 public static IList<T> GetEntityList<T>(IList<ICriterion> whereCondition,IList<string> orderColumnList)
         {
             Helper.Session.Clear();
             ICriteria criteria = Session.CreateCriteria(typeof(T));
 
             if (whereCondition != null && whereCondition.Count > )
             {
                 foreach (ICriterion cri in whereCondition)
                 {
                     criteria.Add(cri);
                 }
             }
 
             if (orderColumnList != null && orderColumnList.Count > )
             {
                 foreach (string orderColumn in orderColumnList)
                 {
                     criteria.AddOrder(Order.Asc(orderColumn));
                 }
             }
 
             return criteria.List<T>();
         }

获取数据实体列表

 public static void ExecuteProcedure(string procedureName, List<ProcedureParameter> lstParameters)
         {
             Helper.Session.Clear();
             try
             {
                 var cmd = Session.Connection.CreateCommand();
 
                 cmd.CommandText = procedureName;
                 cmd.CommandType = CommandType.StoredProcedure;
                 foreach (var para in lstParameters)
                 {
                     var iPara = cmd.CreateParameter();
                     iPara.ParameterName = para.ParameterName;
                     iPara.Value = para.Value;
                     iPara.Direction = para.Direction;
                     iPara.DbType = para.DataType;
                     if (para.Size != )
                     {
                         iPara.Size = para.Size;
                     }
                     cmd.Parameters.Add(iPara);
                 }
                 cmd.ExecuteNonQuery();
 
                 foreach (var p in lstParameters)
                 {
                     if (p.Direction == ParameterDirection.Output)
                     {
                         p.Value = ((System.Data.Common.DbParameter)cmd.Parameters[p.ParameterName]).Value;
                     }
                 }
             }
             catch(Exception ex)
             {
                 throw ex;
             }
         }

执行存储过程

3.建立单元测试项目

略

最后，我知道没有代码你们是不会来的，so，如下 ：
