推荐答案

这里有两个部分. br/>
首先，这是关于表单协作的流行问题.最健壮的解决方案是在Form类中实现适当的接口，并传递接口引用而不是对Form的整个实例"的引用.请查看我过去的解决方案以获取更多详细信息:如何以两种形式在列表框之间复制所有项目 [ http://en.wikipedia.org/wiki/Multiple_document_interface#Disadvantages [在WPF中使用MDI窗口的问题 [ ^ ]，

There are two parts here.

First, this is the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class and passing the interface reference instead of reference to a "whole instance" of a Form. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].

Second part is this: stop torturing yourself and scare off your users! Get rid of MDI, this is a really ugly thing discouraged even by Microsoft. I can tell you what to do instead to get much nicer design options which are much easier to implement. Please see:
