在Entity Framework4中执行T-sql语句

可以使用ExecuteStoreQuery<T>方法：

   1:          [Test]

   2:          public void ExecuteTSQLInEF4()

   3:          {

   4:              using (var context = new AdventureWorksEntities())

   5:              {

   6:                  var query = context.ExecuteStoreQuery<Employee>("SELECT TOP 10 * FROM HumanResources.Employee");

   7:                  foreach (var employee in query)

   8:                  {

   9:                      Console.WriteLine(employee.Title);

  10:                  }

  11:              }

  12:              Console.ReadLine();

  13:          }

T是Genric,可参考MSDN

使用ExecuteStoreCommand 方法：

这个更加灵活，你可以执行Update,Insert语句

   1:          [Test]

   2:          public void ExecuteTSQLInEF4_Part2()

   3:          {

   4:              using (var context = new AdventureWorksEntities())

   5:              {

   6:                  var query = context.ExecuteStoreCommand("SELECT TOP 10 * FROM HumanResources.Employee");

   7:                  foreach (var employee in query)

   8:                  {

   9:                      Console.WriteLine(employee.Title);

  10:                  }

  11:              }

  12:              Console.ReadLine();

  13:          }

代码很简单，您只要对Entity Framework有一定了解，可以看懂上面的代码。EF4中ObjectContext提供了比较多的方法供我们使用。
