從列表中選擇項目並將它們添加到列表中？

嗨我正在爲我使用C＃WPF和MVVM模式的網絡應用程序工作。這將是一個快速配置應用程序，以便用戶可以從應用程序配置設備。混淆的問題是我想要獲取有關vlans的信息，並且可能有多個用戶可以創建的vlans。所以我需要同時從用戶那裏獲取多個信息，最後我會通過telnet命令配置所有的值。從用戶那裏獲取多個輸入並將其存儲到最終以便它可以正確配置的可能和簡單的方法是什麼？建議將非常可觀。從列表中選擇項目並將它們添加到列表中？

我對VLAN視圖模型代碼是：

public class VLANSViewModel : WizardPageViewModelBase 
    {

    public VLANSViewModel(ConfigurationLibrary configuration)

    #endregion // end region fields

我想在同一時間保存的VLAN值的多個值。現在有什麼建議？

你想如何獲得用戶輸入？通過GUI？通過命令行？某種提示？ – ZivS

如果你描述輸入格式，它也會更容易幫助你 – ZivS

我想你正在尋找一個很好的介紹，從頭開始學習一個可以正確處理模型的MVVM應用程序。在這種情況下，我建議使用「入門MVVM」guid，例如this one in Catel。

從列表中選擇項目並將它們添加到列表中？
