c# - “当前上下文中不存在名称‘参数’”与 IParamDynamic

Question

我在以下代码中收到错误，因为错误位置的注释：

using Autodesk.iLogic.Interfaces;
using System;
using System.Windows.Forms;

namespace DllTest
{
    public partial class Form1 : Form
    {
        public IParamDynamic Parameter = null;  // From Autodesk.iLogic.Interfaces        

        public double x;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            x = Parameter("myVariable"); //Error: The name 'Parameter' does not exist in the current context.
        }
    }
}  

谁能帮帮我？非常感谢！
