1、我的测试代码：

namespace RefTest01{    [UnmanagedFunctionPointer(CallingConvention.StdCall)]    public delegate void D_Test01(int _i);    // ***    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void button2_Click(object sender, EventArgs e)        {
    /*            if (FfnTest01 == null)                MessageBox.Show("FfnTest01 == null");            else                FfnTest01(3);          //*/            Type delegateType = typeof(D_Test01);            MethodInfo method = delegateType.GetMethod("Invoke");            Console.WriteLine(method.ReturnType.Name + " (ret)");            foreach (ParameterInfo param in method.GetParameters())            {                Console.WriteLine("{0} {1}", param.ParameterType.Name, param.Name);            }        }    }}

　　打印信息：

Void (ret)Int32 _i
