将变量从主窗体传递给输入表单 [英] Passing variables from main form to input form

问题描述

我有一个简单的问题。我有一个主窗体，然后是一个启动窗体，从那里我可以选择一个新的3D模型来生成。从启动窗体中选择新的3D模型时，首先要检查我以前的模型是否已被保存。我只想使用一个委托将主窗体的布尔值传递给启动窗体，但是我似乎无法访问主窗体或其任何变量。我以为这么简单：< code> frmMain myForm = new frmMain（）;< / code>，但是键入frmMain在智能感知中不会显示任何内容。

任何提示？

解决方案

在主窗体上添加公共资源

  public bool IsDirty 
 {
 get; set; 
} 
  

然后您可以访问 this.ParentForm.IsDirty 在您的启动表单中，

记得在显示启动窗体时传递对主窗体的引用... startupForm.showDialog（this）;

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.

Any hints?

解决方案

Add a public property on your main form

public bool IsDirty
{
    get;set;
}

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

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