取得所有网卡的MAC地址，包括禁用的

先在nuget包中添加System.Management.Automation引用。

然后下面就是代码了。

using System;
using System.Collections.ObjectModel;
using System.Management.Automation;
using System.Text;
using System.Windows.Forms;

namespace GetMAC
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

private void button1_Click(object sender, EventArgs e)
        {
            StringBuilder sb = new StringBuilder();
            using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                PowerShellInstance.AddCommand("Get-NetAdapter");

Collection<PSObject> PSOutput = PowerShellInstance.Invoke();

foreach (PSObject result in PSOutput)
                {
                    sb.Append(result.Members["PermanentAddress"].Value + "\r\n");
                }
            }
            textBox1.Text = sb.ToString();
        }

}
}
