wpf中的listview输出

Question

我正在尝试在wpf中制作一个wifi扫描程序，我尝试在Windows窗体应用程序中，它通过c＃完美地工作但我在wpf中使用以下代码获取了listview第一列的重复输出

＆LT;

       <ListView.View>
            <GridView>
                <GridViewColumn Width="100 "/>
                <GridViewColumn Width="100"/>
                <GridViewColumn Width="100"/>
             </GridView>
        </ListView.View>



and code behind
Wlan.WlanAvailableNetwork[] networks = wlanInterface.GetAvailableNetworkList(0);
            foreach(Wlan.WlanAvailableNetwork network in networks)
            {
                Wlan.Dot11Ssid ssid = network.dot11Ssid;
                string networkname = Encoding.ASCII.GetString(ssid.SSID, 0, (int)ssid.SSIDLength);
                System.Windows.Forms.ListViewItem item = new System.Windows.Forms.ListViewItem(networkname);
                item.SubItems.Add(network.dot11DefaultCipherAlgorithm.ToString());
                item.SubItems.Add(network.wlanSignalQuality + "%");
                lv1.Items.Add(item);
