IrisSkin2的使用问题

Question

为什么用IrisSkin2控件会让我的程序经常出现 “未将对象引用设置到对象的实例”，皮肤控件已经引用成功，效果已经有了，就是一个窗体开了关、关了开，次数多了就有“未将对象引用设置到对象的实例”的错误。求解，谢谢

Answer 1

這個是垃圾的，很多bug，等你程序做好了，你就會後悔

其实我是想实现换肤功能的，好像不换肤的话就没问题，但是只要点了一下要换肤的设置界面，然后关掉，在点其它窗口，多点几次就有问题，忒悲
 private void comboBskin_SelectedIndexChanged(object sender, EventArgs e)
        {
            loginform = new LoginForm();
            if (this.comboBskin.Text == "默认")
            {
               
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\corona-CORONA12.skn";
            }
            else if (this.comboBskin.Text == "blue")
            {
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Plex Style-M6SVRBAR.skn";
            }
            else if (this.comboBskin.Text == "luna")
            {
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\luna-HOMESTEAD.skn";
            }
            else if (this.comboBskin.Text == "Plex Style")
            {
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Mac OS X-BLUE.skn";
            }
            else if (this.comboBskin.Text == "Tiger")
            {
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Tiger-TGR.skn";
            }
            else if (this.comboBskin.Text == "ProLCD")
            {
                loginform.skinUI1.SkinFile = Application.StartupPath + "\\skins\\ProLCD-PROLCDAC.skn";
            }
        }
在登录界面中（LoginForm中）
 switch (shinname)
            {
                case "默认":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\corona-CORONA12.skn";
                        break;
                    }
                case "blue":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Plex Style-M6SVRBAR.skn";
                        break;
                    }
                case "luna":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\luna-HOMESTEAD.skn";
                        break;
                    }
                case "Plex Style":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Mac OS X-BLUE.skn";
                        break;
                    }
                case "Tiger":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\Tiger-TGR.skn";
                        break;
                    }
                case "ProLCD":
                    {
                        this.skinUI1.SkinFile = Application.StartupPath + "\\skins\\ProLCD-PROLCDAC.skn";
                        break;
                    }
            }
有问题吗？
