从列表中选择项目并将它们添加到列表中？

嗨我正在为我使用C＃WPF和MVVM模式的网络应用程序工作。这将是一个快速配置应用程序，以便用户可以从应用程序配置设备。混淆的问题是我想要获取有关vlans的信息，并且可能有多个用户可以创建的vlans。所以我需要同时从用户那里获取多个信息，最后我会通过telnet命令配置所有的值。从用户那里获取多个输入并将其存储到最终以便它可以正确配置的可能和简单的方法是什么？建议将非常可观。从列表中选择项目并将它们添加到列表中？

我对VLAN视图模型代码是：

public class VLANSViewModel : WizardPageViewModelBase 
    { 
    #region Fields 


    #endregion // end region fields 

    #region Constructor 

    public VLANSViewModel(ConfigurationLibrary configuration)

     VlanIP2 = "168";

    #endregion 

    #region Properties

    #endregion // end region fields 

    public override string DisplayName

我想在同一时间保存的VLAN值的多个值。现在有什么建议？

你想如何获得用户输入？通过GUI？通过命令行？某种提示？ – ZivS

如果你描述输入格式，它也会更容易帮助你 – ZivS

我想你正在寻找一个很好的介绍，从头开始学习一个可以正确处理模型的MVVM应用程序。在这种情况下，我建议使用“入门MVVM”guid，例如this one in Catel。
