Question

大家好，我有一个问题，我想将我的WPF组合框与我使用正则表达式提取的值绑定。这是我的代码：

string pattern = "/^dhcp pool.*/g";
Console.WriteLine(pattern);
MatchCollection matches = Regex.Matches(_str, pattern);

foreach(Match match in matches)
{
    Console.WriteLine("+++++++++++++dhcp pool is ++++++++++++++" + match.Groups[1].Value);
    DHCPoolName = match.Groups[1].Value;
}

DHCPPoolName是我绑定为我的组合框的ItemSorurce的属性的名称。

XAML代码：

<ComboBox
    Grid.Column="1"
    Grid.Row="1"
    Margin="0,4"
    ItemsSource="{Binding DHCPoolName}">              
</ComboBox>

DHCPPoolName属性：

 public string DHCPoolName
        {

            // Retreive value from Configuration Library
            get
            {
                //Console.WriteLine("get WpaWpa2RadiusKey");
                return this.ConfigurationLibrary.ConfigLibraryDhcpPoolName;
            }

            // Set value in Configuration Library
            set
            {
                if (!String.Equals(this.ConfigurationLibrary.ConfigLibraryDhcpPoolName, value))
                {
                    //Console.WriteLine("set WpaWpa2RadiusKey");
                    this.ConfigurationLibrary.ConfigLibraryDhcpPoolName = value;

                    // ValidateWLAN1RadiusKey(value);

                    this.OnPropertyChanged("DHCPoolName");
                }
            }
        }

我没有成功地将我的组合框与我提取的值绑定，任何人都可以告诉我我在哪里做错了吗？

您可以定义字符串Collection

private ObservableCollection<string> dhcppoolname;
 public ObservableCollection<string> DHCPoolName
    {
        get
        {
            if(dhcppoolname == null)
            {
                dhcppoolname = new ObservableCollection<string>();
            }
            return dhcppoolname;
        }
        set
        {
            dhcppoolname = value;
            OnPropertyChanged("DHCPoolName");
        }
    }

在foreach循环中

    foreach(Match match in matches)
   {
      Console.WriteLine("+++++++++++++dhcp pool is ++++++++++++++" + match.Groups[1].Value);
      DHCPoolName.Add(match.Groups[1].Value);
   }

如何将组合框与正则表达式提取的值绑定？
