c# - 动态调用具有复杂参数的方法 (C#)

Question

我想调用 method1在class1 dynamically .我不想使用 Prm class直接地。如何发送p parameter dynamically . Here是一种方式，但我无法管理

namespace WindowsFormsApplicationMethodCall
{
    public class Prm
    {
        public string p1 { get; set; }
        public long p2 { get; set; }
    }
    public class Class1
    {
        public string Method1(Prm p)
        {
            return "Hello world";
        }
    }
}

用法:

private void button1_Click(object sender, EventArgs e)
{
  var ass = Assembly.LoadFrom("abc.dll");
  var business = ass.CreateInstance("WindowsFormsApplicationMethodCall.Class1");
  var mInfo = business.GetType().GetMethod("Method1");
  var anonymParameter = new { p1 = "", p2 = 2 };
  mInfo.Invoke(business,new object[]{ anonymParameter});
  //var res = mInfo.TolerantCast(new { p1 = "", p2 = 2 });
  //var param = new Dictionary<string,object>();
  //param.Add("p", result);                
}

我发现了这个错误:<>f__AnonymousType0`2[System.String,System.Int32] 类型的对象无法转换为类型

从类“Prm”创建实例并改为使用它

var anonymParameter = new { p1 = "", p2 = 2 };

to

var anonymParameter  = ass.CreateInstance("WindowsFormsApplicationMethodCall.Prm");
anonymParameter.GetType().GetProperty("p1").SetValue(anonymParameter,""); 
anonymParameter.GetType().GetProperty("p2").SetValue(anonymParameter,2);
