这几天在玩儿Vault API， 从Autodesk Vault 2014开始提供了Vault Development Framework（VDF） API，让开发工作更简单了。在Vault 2013里面可以使用PropertyService 来获取属性（包括属性定义和属性至），在Vault 2014中的VDF API里，我们可以通过PropertyManager来获取。下面代码演示了如何登录到Vault并取得PropertyManager:
前面的文章提到了使用VDF内置的登录对话框登录非常简单，如果你不用使用那个登录框，也可以自己做界面，使用下面的*面的登录方式：
////login with UI
//VDF.Vault.Currency.Connections.Connection connection = VDF.Vault.Forms.Library.Login(new VDF.Vault.Forms.Settings.LoginSettings()); //Another way to log into Vault without UI
VDF.Vault.Results.LogInResult results =
VDF.Vault.Library.ConnectionManager.LogIn(
"localhost", "Vault", "Administrator", "",
VDF.Vault.Currency.Connections.AuthenticationFlags.Standard, null);
if (!results.Success)
{
Console.WriteLine("Login failed. exit...");
Console.ReadLine();
return;
} VDF.Vault.Currency.Connections.Connection connection = results.Connection; VDF.Vault.Services.Connection.IPropertyManager propMgr = connection.PropertyManager;
这个例子中，我要递归的获取Vault中所有的目录和文件，看到这几个字，我首先想到的就是用FileManager和FolderManager，不过这两个家伙对于获取文件本身，比如checkout并下载等工作来说很好用，我其实只要获取FileInteration进而获取他们的属性，所有FileManager和FolderManager并不是好办法。同事提醒我可以用IEntityOperationManager。 Folder和File等都是Entity，对于这些Entity的操作还有一个更底层的IEntityOperationManager， 其实FileManger和FolderManager也是调用的IEntityOperationManager。通过IEntityOperationManager的GetBrowseChildren方法就可以获取指定entity的所有子实体，就可以实现递归获取所有文件了。
好了，下面是代码：

using System;
using System.Collections.Generic;
using System.Linq;
using VDF = Autodesk.DataManagement.Client.Framework;

{
////login with UI
//VDF.Vault.Currency.Connections.Connection connection

//Another way to log into Vault without UI
VDF.Vault.Results.LogInResult results =
VDF.Vault.Library.ConnectionManager.LogIn(
"localhost", "Vault", "Administrator", "",
VDF.Vault.Currency.Connections.AuthenticationFlags.Standard, null);
if (!results.Success)
{
Console.WriteLine("Login failed. exit...");
Console.ReadLine();
return;
}
VDF.Vault.Currency.Connections.Connection connection = results.Connection;
if (connection.IsConnected)
{
ReadProperties(connection);
VDF.Vault.Currency.Entities.Folder folder = connection.FolderManager.RootFolder;
PrintChildren(connection, folder);

{

object propValue = connection.PropertyManager.GetPropertyValue(
