如何在运行时在c#中动态创建模型

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

public class Program
{
    public static void Main()
    {
        // 创建一个动态程序集
        AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
        AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run);
        
        // 创建一个动态模块
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule");
        
        // 创建一个动态类型
        TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicModel", TypeAttributes.Public);
        
        // 添加属性到动态类型
        typeBuilder.DefineField("id", typeof(int), FieldAttributes.Private);
        typeBuilder.DefineField("name", typeof(string), FieldAttributes.Private);
        
        // 创建构造函数
        ConstructorBuilder constructorBuilder = typeBuilder.DefineConstructor(MethodAttributes.Public, CallingConventions.Standard, new Type[] { typeof(int), typeof(string) });
        ILGenerator constructorIL = constructorBuilder.GetILGenerator();
        constructorIL.Emit(OpCodes.Ldarg_0);
        constructorIL.Emit(OpCodes.Call, typeof(object).GetConstructor(Type.EmptyTypes));
        constructorIL.Emit(OpCodes.Ldarg_0);
        constructorIL.Emit(OpCodes.Ldarg_1);
        constructorIL.Emit(OpCodes.Stfld, typeBuilder.GetField("id"));
        constructorIL.Emit(OpCodes.Ldarg_0);
        constructorIL.Emit(OpCodes.Ldarg_2);
        constructorIL.Emit(OpCodes.Stfld, typeBuilder.GetField("name"));
        constructorIL.Emit(OpCodes.Ret);
        
        // 创建动态类型
        Type dynamicType = typeBuilder.CreateType();
        
        // 创建动态对象
        object dynamicObject = Activator.CreateInstance(dynamicType, 1, "Dynamic Model");
        
        // 使用动态对象
        Console.WriteLine(dynamicObject.GetType().Name);
        Console.WriteLine(dynamicObject.GetType().GetProperty("id").GetValue(dynamicObject));
        Console.WriteLine(dynamicObject.GetType().GetProperty("name").GetValue(dynamicObject));
    }
}
