what's new in vs 2005

 

1. 泛型约束很少，可以是 :new(), class, classtype,interface type,struct
2. 对于fileIO，可以很容易获取起ACL信息。
3. 对于XML，可以使用XSD这个工具获取（infer）XML的XSD
4. 匿名方法
1. // anonymous method
   MessagePrintDelegate mpd2 = delegate(string msg)
   {
   Console.WriteLine("[Anonymous] {0}", msg);
   };
   
5. 资源模型，strongtyped resource
6. ADO.NET
1. Datatable 可以创建一个DataTableReader，以reader的方式访问datatable
1. DataTable dt = new DataTable("Customers");
   // load data from previous demo
   dt.ReadXml(@"..\..\..\..\TableXml\TableXml\bin\debug\Customers.xml");
   DataTableReader dtr = dt.CreateDataReader();
   while (dtr.Read())
   {
   Console.WriteLine("[{0}] {1} {2}",
   (int)dtr["CustomerID"],
   (string)dtr["FirstName"], (String)dtr["LastName"]);
   }
   Console.ReadLine();
   
2. 异步的调用方法，BeginXXX
3. DataAdapter 的批量更新数据苦，可以设置一个batchupdate size
1. SqlDataAdapter da = new SqlDataAdapter(selectCmd) ;
   da.UpdateCommand = updateCmd;
   da.InsertCommand = insertCommand;
   da.UpdateBatchSize = 10;
   
4. Transaction Scope
5. Provider 模型，更容易实现共产访问DAC
1. DbProviderFactory factory =
   DbProviderFactories.GetFactory("System.Data.SqlClient");
   DbConnection conn = factory.CreateConnection();
   conn.ConnectionString =
   "data source=localhost; initial catalog=SampleDB; Integrated Security=SSPI;";
   conn.Open();
   
6. Managed SP
7. ASP.NET 2.0
8. Remoting 可以用泛型
1. RemotingConfiguration.RegisterWellKnownServiceType(
   typeof(SharedObjectImplementation<string>),
   "StringObject.rem",
   WellKnownObjectMode.SingleCall);
   RemotingConfiguration.RegisterWellKnownServiceType(
   typeof(SharedObjectImplementation<DateTime>),
   "DateObject.rem",
   WellKnownObjectMode.SingleCall);
