c# 创建窗口句柄出错

Question

主窗体代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Sunisoft.IrisSkin;namespace xr
{
    public partial class Form1 : Form
    {
        SkinEngine skinEngine1 = null;
        public Form1()
        {
  skinEngine1 = new SkinEngine();
            skinEngine1.SkinAllForm = true;
            InitializeComponent();            //this.skinEngine1.SkinFile = "DiamondGreen.ssk";
        }        private void 流量ToolStripMenuItem1_Click(object sender, EventArgs e)
        {        }        private void 流量阻力损失ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            //子窗体
            LZ fm = new LZ();
            fm.MdiParent = this;
            fm.Show();
        }        private void wg1_Click(object sender, EventArgs e)
        {
            if (!wg1.Checked)
            {
                wg1.Checked = true;
                wg2.Checked = false;
            }
            Form1_Load(sender, e);
        }        private void wg2_Click(object sender, EventArgs e)
        {
          if (!wg2.Checked)
            {
                wg2.Checked = true;
                wg1.Checked = false;
            }
            Form1_Load(sender, e);
        }        private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                string style = "";
                if (wg1.Checked)
                {
                    style = "DiamondBlue.ssk";
                }
                else
                {
                    style = "DiamondGreen.ssk";
                }
                skinEngine1.SkinFile = style;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
      
    }
}运行时
namespace xr
{
    static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());此处提示创建窗口句柄出错
        }
    }
}但是把绿色的去掉，就可以运行。
小弟是新手不大懂。

看了一下，是不是这两个代码有问题：skinEngine1 = new SkinEngine();
skinEngine1.SkinAllForm = true;
