问题描述

我正在尝试检索IP地址。

但它给出了这个例外

对象引用未设置为实例一个对象。

am trying to retrieve ip address.
but it's giving this exception
"Object reference not set to an instance of an object."

ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\cimv2");
            ObjectQuery query1 = new ObjectQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
            ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);
            ManagementObjectCollection queryCollection = searcher1.Get();

            foreach (ManagementObject m in queryCollection)
            {

                listBox2.Items.Add(m["DefaultIPGateway"].ToString());
            }

任何人都可以解决此查询。

推荐答案

ManagementObjectCollection queryCollection = new ManagementObjectCollection（）;

queryCollection = searcher1.Get（）;





试试这个

ManagementObjectCollection queryCollection = new ManagementObjectCollection();
queryCollection = searcher1.Get();


try this

使用Visual Studio交互式调试器，我能够使用以下代码获取IPAddress：

Using the Visual Studio interactive debugger, I was able to get the IPAddress using this code:

ManagementScope scope = new ManagementScope(@"\\.\ROOT\CIMV2");
ObjectQuery query1 = new ObjectQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);
ManagementObjectCollection queryCollection = searcher1.Get();

foreach (ManagementObject m in queryCollection)
{
    string[] addr = (string[])m.GetPropertyValue("IPAddress");
    if (addr != null)
    {
        Console.WriteLine(addr[0]);
    };
}
