C# 获得本地通用网卡信息

可以通过使用命名空间下的ManagementObjectSearcher类及其方法Get来获得通用网卡信息。

其中，最重要的是ManagementObjectSearcher构造函数的输入参数，可以传入以下的QueryString。

SELECT * FROM Win32_NetworkAdapterConfiguration

以下的例子为将本地网卡的配置信息写入一个文件并保存，代码如下：

using System.IO;
using System.Linq;
using System.Management;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration") ;
            ManagementObjectCollection managementObjectCollection = managementObjectSearcher.Get();
            StreamWriter writer = new StreamWriter("result.csv");
            bool isFirstRow = true;
            foreach (ManagementObject managementObject in managementObjectCollection)
            {
                string header = string.Empty;
                string content = string.Empty;
                string separator1 = ",";
                string separator2 = " | ";
                foreach (var item in managementObject.Properties)
                {
                    if (isFirstRow)
                    {
                        header = $"{header}{separator1}{item.Name}";
                    }
                    string valueTemp = string.Empty;
                    if (item.Value != null)
                    {
                        if (item.Value is string[]  || item.Value is ushort[])
                        {
                            string[] valuesStrTemp;
                            if(item.Value is ushort[])
                                valuesStrTemp = ((ushort[])item.Value).Select(x => x.ToString()).ToArray();
                            else
                                valuesStrTemp = item.Value as string[];

                            for (int i = 0; i < valuesStrTemp.Length; i++)
                            {
                                valueTemp = $"{valueTemp}{separator2}{valuesStrTemp[i]}";
                            }
                            if(valuesStrTemp.Length != 0)
                                valueTemp = valueTemp.Remove(0, separator2.Length);
                        }
                        else
                            valueTemp = item.Value.ToString();
                    }
                    content = $"{content}{separator1}{valueTemp}";
                }
                if (isFirstRow)
                {
                    header = header.Remove(0, separator1.Length);
                    writer.WriteLine(header);
                    isFirstRow = false;
                }
                content = content.Remove(0, separator1.Length);
                writer.WriteLine(content);
            }
            writer.Close();
        }
    }
}

运行结果如下：
