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

运行结果如下：
