C# WPF 创建一个动态程序集 把MAC 地址保存进去

以下是一个示例代码，展示如何创建一个动态程序集，并将MAC地址保存在其中：

using System;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;

namespace DynamicAssemblyExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建动态程序集
            AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
            AssemblyBuilder dynamicAssembly = AssemblyBuilder.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);

            // 创建动态模块
            ModuleBuilder dynamicModule = dynamicAssembly.DefineDynamicModule("DynamicModule", "DynamicAssembly.dll");

            // 创建动态类
            TypeBuilder dynamicClass = dynamicModule.DefineType("DynamicClass", TypeAttributes.Public);

            // 添加字段来保存MAC地址
            FieldBuilder macAddressField = dynamicClass.DefineField("MacAddress", typeof(string), FieldAttributes.Public);

            // 添加构造函数
            ConstructorBuilder constructor = dynamicClass.DefineConstructor(MethodAttributes.Public, CallingConventions.Standard, new Type[0]);
            ILGenerator constructorIL = constructor.GetILGenerator();
            constructorIL.Emit(OpCodes.Ldarg_0);
            constructorIL.Emit(OpCodes.Call, typeof(object).GetConstructor(Type.EmptyTypes));
            constructorIL.Emit(OpCodes.Ret);

            // 创建类的实例
            Type dynamicType = dynamicClass.CreateType();
            object dynamicObject = Activator.CreateInstance(dynamicType);

            // 获取MAC地址
            string macAddress = GetMacAddress();

            // 设置动态类的字段值
            dynamicType.GetField("MacAddress").SetValue(dynamicObject, macAddress);

            // 保存动态程序集至磁盘
            dynamicAssembly.Save("DynamicAssembly.dll");

            Console.WriteLine("Dynamic assembly created and saved successfully!");
        }

        static string GetMacAddress()
        {
            // 获取本机的MAC地址
            var macAddresses = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()
                .Where(nic => nic.OperationalStatus == System.Net.NetworkInformation.OperationalStatus.Up && nic.NetworkInterfaceType != System.Net.NetworkInformation.NetworkInterfaceType.Loopback)
                .Select(nic => nic.GetPhysicalAddress().ToString())
                .ToList();

            return macAddresses.FirstOrDefault();
        }
    }
}

运行这段代码后，它将创建一个名为 "DynamicAssembly.dll" 的动态程序集，并将本机的第一个有效MAC地址保存在其中的 MacAddress 字段中
