Question

您好我正在开发一个网络应用程序，我正在使用C＃WPF和MVVM模式。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，并且用户可以创建多个vlan。所以我需要同时从用户那里获取多个信息，最后我将通过telnet命令配置所有值。从用户那里获取多个输入并将其存储到最终以便可以正确配置的可能和简单方法是什么？建议会非常明显。

我的VLAN ViewModel代码是：

  public class VLANSViewModel : WizardPageViewModelBase
  {
    #region Fields


    #endregion // end region fields

    #region Constructor

    public VLANSViewModel(ConfigurationLibrary configuration)
      : base(configuration)
    {
      VlanIP1 = "192";
      VlanIP2 = "168";
      VlanIP3 = "1";
      VlanIP4 = "1";
    }
    #endregion

    #region Properties


    public string VlanName
    {
      get

        {
          return;

        this.ConfigurationLibrary.ConfigLibraryVlanName = value;
        this.OnPropertyChanged("VlanName");

我想一次为VLAN值保存多个值。现在有什么建议吗？

Answer 1

我认为您正在寻找一个很好的介绍，从头开始到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＆＃34;开始使用MVVM＆＃34; guid，如this one in Catel。

从列表中选择项目并将其添加到列表中？
