C# 获得本地通用网卡信息的示例代码

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：
