如何在SQL Server中使用SMO自动生成脚本？

我想在SSMS 2008中自动生成脚本（在SSMS中 - >任务 - >生成脚本）。我已经读过SQL Server 2008不支持数据库发布向导（包括SQLPUBWIZ SCRIPT）但这种自动化可以在SQL Server 2008中使用SMO完成。我没有关于SMO的线索以及如何使用SMO做到这一点，所以你能给我一些建议（资源等）如何开始吗？

SMO脚本的关键是Scripter类。所有其他工具（如SSMS）使用此类生成对象创建脚本。 MSDN上有一个示例用法：

{ 
   //Connect to the local, default instance of SQL Server. 
  Server srv = new Server(); 

   //Reference the AdventureWorks2008R2 database.  
  Database db = srv.Databases["AdventureWorks2008R2"]; 

   //Define a Scripter object and set the required scripting options. 
  Scripter scrp = new Scripter(srv); 
   scrp.Options.ScriptDrops = false; 
   scrp.Options.WithDependencies = true; 

   //Iterate through the tables in database and script each one. Display the script. 
   //Note that the StringCollection type needs the System.Collections.Specialized namespace to be included. 
   Microsoft.SqlServer.Management.Sdk.Sfc.Urn[] smoObjects = new Microsoft.SqlServer.Management.Sdk.Sfc.Urn[1] ;
   foreach (Table tb in db.Tables) {   
      smoObjects[0] = tb.Urn; 
      if (tb.IsSystemObject == false) { 
         System.Collections.Specialized.StringCollection sc;
         sc = scrp.Script(smoObjects); 
         foreach ( string st in sc) { 
            Console.WriteLine(st); 
         } 
      } 
   } 
}

虽然这个问题已经得到了准确的回答，但我还是花了几天的时间来整理一个脚本，该脚本编写了我在数据库服务器上关注的所有对象。这是我的代码，以防它在某些时候对其他人有用。

有几种方法可以编写数据库中的所有对象，但最简单的方法之一是SMO传输类。下面是一些脚本化所有对象的PowerShell代码：

add-type -AssemblyName "Microsoft.SqlServer.ConnectionInfo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
add-type -AssemblyName "Microsoft.SqlServer.Smo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
add-type -AssemblyName "Microsoft.SqlServer.SMOExtended, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"

$sourceSrv = "$env:computername\sql2k8"
$sourceDb = "Northwind"

$server =  new-object ("Microsoft.SqlServer.Management.Smo.Server") $sourceSrv
$db = $server.Databases[$sourceDb]

$transfer = new-object ("Microsoft.SqlServer.Management.Smo.Transfer") $db
$transfer.CopyAllObjects = $true
$transfer.DropDestinationObjectsFirst = $true
$transfer.CopySchema = $true
$transfer.Options.IncludeIfNotExists = $true

$transfer.ScriptTransfer()
