补充：
webBrowser1.ObjectForScripting = this;
这句话的意思是webBrowser1的脚本执行的Com绑定的方法是 从Form1 来的，
而MyMessageBox1和ShowForm
却是在WinOperationClass
类里面的，肯定是不行的
第一个可以是因为form1里面有MyMessageBox这个方法
你吧MyMessageBox1和ShowForm移动到form1中或者把MyMessageBox移动到WinOperationClass里面，再把 webBrowser1.ObjectForScripting = this;这句改成
WinOperationClass w=new WinOperationClass();
webBrowser1.ObjectForScripting = w;
就可以了
推荐第二种……把所有的 Com可见的方法放在一个类里面好维护
