C# WPF 创建一个动态程序集 把MAC 地址保存进去在读取文件获取MAC值

要创建一个动态程序集，可以使用C#中的AssemblyBuilder类。以下是一个例子，展示了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.IO;
using System.Reflection;
using System.Reflection.Emit;

public class Program
{
    public static void Main(string[] args)
    {
        // 获取MAC地址
        string macAddress = GetMacAddress();

        // 创建动态程序集
        AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
        AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);

        // 创建模块
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule", "DynamicAssembly.dll");

        // 创建类
        TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicClass", TypeAttributes.Public);

        // 创建字段
        FieldBuilder fieldBuilder = typeBuilder.DefineField("MacAddress", typeof(string), FieldAttributes.Public | FieldAttributes.Static);

        // 在类的静态构造函数中保存MAC地址
        ConstructorBuilder constructorBuilder = typeBuilder.DefineConstructor(MethodAttributes.Static, CallingConventions.Standard, Type.EmptyTypes);
        ILGenerator constructorIL = constructorBuilder.GetILGenerator();
        constructorIL.Emit(OpCodes.Ldstr, macAddress);
        constructorIL.Emit(OpCodes.Stsfld, fieldBuilder);
        constructorIL.Emit(OpCodes.Ret);

        // 创建类并保存程序集
        Type dynamicType = typeBuilder.CreateType();
        assemblyBuilder.Save("DynamicAssembly.dll");

        // 使用反射读取MAC地址
        Assembly dynamicAssembly = Assembly.LoadFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "DynamicAssembly.dll"));
        Type dynamicClassType = dynamicAssembly.GetType("DynamicClass");
        FieldInfo macAddressField = dynamicClassType.GetField("MacAddress", BindingFlags.Public | BindingFlags.Static);
        string savedMacAddress = (string)macAddressField.GetValue(null);

        Console.WriteLine("Saved MAC Address: " + savedMacAddress);
    }

    private static string GetMacAddress()
    {
        // 获取MAC地址的代码
        // ...
        return "00-00-00-00-00-00"; // 假设获取到了MAC地址，并返回
    }
}

这段代码将创建一个名为DynamicAssembly.dll的动态程序集，并在其中保存了MAC地址。然后，使用反射从程序集中读取保存的MAC地址。请确保将GetMacAddress()方法替换为实际获取MAC地址的代码
