将变量从主表单传递到输入表单 [英] Passing variables from main form to input form

问题描述

我有一个简单的问题.我有一个主表单，然后是一个启动表单，我可以从中选择一个新的 3D 模型来生成.从启动表单中选择新的 3D 模型时，我想首先检查我之前处理的模型是否已保存.我只是想使用委托将一个布尔值从主窗体传递给启动窗体，但我似乎无法访问主窗体或其任何变量.我认为这很简单:<code>frmMain myForm = new frmMain();</code>，但是在智能感知中输入 frmMain 不会显示任何内容.

I have a simple question. I have a main form, and then a startup form from where I can select a new 3D model to generate. When selecting a new 3D model from the startup form, I want to check first whether the previous model I worked on has been saved or not. I simply want to pass a boolean value from the main form to the startup form using a delegate, but I can't seem to access the main form or any of its variables. I thought it would be as simple as saying: <code>frmMain myForm = new frmMain();</code>, but typing frmMain doesn't show up anything in intellisense.

有什么提示吗?

推荐答案

在主窗体上添加公共属性

Add a public property on your main form

public bool IsDirty
{
    get;set;
}

然后您可以在启动表单中访问 this.ParentForm.IsDirty，

you can then access this.ParentForm.IsDirty in your startup form,

记得在显示启动表单时传递对主表单的引用... startupForm.showDialog(this);

remember to pass a reference to the main form when you show the startup form ... startupForm.showDialog(this);
