请问怎么修改啊，急求，谢谢啦

你代码无限循环了，你在form1中有new Calculate.Calculate();
然后在Calculate中又有new Form1();最终就是一个无限实例化的循环过程。
其实完全没必要做这做，你的Calculate只是单纯的计算，所以完全可以将public void calculate更改为比如public static string calculate，然后Calculate中也不涉及任何对form1操作，在form1中调用的时候就可以不用实例化Calculate，直接写
textBox1.Text=Calculate.calculate(参数);
