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);
