如何从il生成器调用Action<string，bool>

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

public class ILGeneratorExample
{
    public static void Main()
    {
        // 创建动态程序集
        AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
        AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run);
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule");
        
        // 创建动态类型
        TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicType", TypeAttributes.Public);
        
        // 创建动态方法
        MethodBuilder methodBuilder = typeBuilder.DefineMethod("DynamicMethod", MethodAttributes.Public | MethodAttributes.Static);
        
        // 定义方法的参数
        methodBuilder.SetParameters(typeof(string), typeof(bool));
        
        // 创建il生成器
        ILGenerator ilGenerator = methodBuilder.GetILGenerator();
        
        // 创建局部变量
        LocalBuilder actionDelegate = ilGenerator.DeclareLocal(typeof(Action<string, bool>));
        
        // 初始化局部变量为Action<string, bool>委托的实例
        ilGenerator.Emit(OpCodes.Ldnull);
        ilGenerator.Emit(OpCodes.Ldftn, typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string), typeof(bool) }));
        ilGenerator.Emit(OpCodes.Newobj, typeof(Action<string, bool>).GetConstructor(new Type[] { typeof(object), typeof(IntPtr) }));
        ilGenerator.Emit(OpCodes.Stloc, actionDelegate);
        
        // 调用Action<string, bool>委托的Invoke方法
        ilGenerator.Emit(OpCodes.Ldloc, actionDelegate);
        ilGenerator.Emit(OpCodes.Ldstr, "Hello, IL Generator!");
        ilGenerator.Emit(OpCodes.Ldc_I4_1);
        ilGenerator.Emit(OpCodes.Callvirt, typeof(Action<string, bool>).GetMethod("Invoke"));
        
        // 返回
        ilGenerator.Emit(OpCodes.Ret);
        
        // 创建动态类型的类型
        Type dynamicType = typeBuilder.CreateType();
        
        // 创建动态方法的委托
        Action<string, bool> dynamicMethodDelegate = (Action<string, bool>)Delegate.CreateDelegate(typeof(Action<string, bool>), dynamicType.GetMethod("DynamicMethod"));
        
        // 调用动态方法
        dynamicMethodDelegate("Hello, Action!", true);
    }
}
