在Autodesk Vault 2014中使用VDF（Vault Development Framework） API获取所有文件的属性信息

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，使用下面的无界面的登录方式：

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

          = 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", "",

        if (!results.Success)
        {
          Console.WriteLine("Login failed. exit...");
          Console.ReadLine();
          return;
        }
 
        VDF.Vault.Currency.Connections.Connection connection = results.Connection;

      IEnumerable<VDF.Vault.Currency.Entities.IEntity> entities = connection
        .EntityOperations.GetBrowseChildren(parentFolder);
      if (entities != null && entities.Count<VDF.Vault.Currency.Entities.IEntity>() > 0)
      {
        foreach (var ent in entities)
        {
          if (ent is VDF.Vault.Currency.Entities.FileIteration)
          {
            VDF.Vault.Currency.Entities.FileIteration fileIteration
              = ent as VDF.Vault.Currency.Entities.FileIteration;
 
            Console.ForegroundColor = ConsoleColor.Green;

            Console.ForegroundColor = ConsoleColor.Yellow;
 
            //Now print the properties of the file
            PrintProperties(connection, fileIteration);
 
 
          }
          else if (ent is VDF.Vault.Currency.Entities.Folder)
          {
            // Recursively print info about subfolders and files in them
            //-------------------------------------------------------------------------
 
            VDF.Vault.Currency.Entities.Folder folder
              = ent as VDF.Vault.Currency.Entities.Folder;

        }
      }

    static void PrintProperties(VDF.Vault.Currency.Connections.Connection connection,

      {
        // Print the Name from the Definition and the Value from the Property
        object propValue = connection.PropertyManager.GetPropertyValue(
