问题描述

朋友们，
我有多种形式.数据互不相同.有些功能是所有表格共有的.我想要的是制作一个父窗体并将通用代码放置在那里.请帮助我如何为所有表格创建共同的父母.
感谢您阅读我的问题.

Hi friends,
I have a number of forms. There data are different from each other. There are some functions that are common to all the forms. What I want is to make a parent form and place the common code there. Please help me how can I create a common parent for all the forms.
thank you for reading my question.

推荐答案

创建一个新的类，如下所示:

Create a new class like this:

public partial class FormBase : Form
{
  // put your common data members/methods in here
}

然后，您可以继承其他所有形式的表单，如下所示:

Then, you can inherit this form in all of your other forms, like this:

public partial class MyForm1 : FormBase
{
}

确保为每个对象都提供一个默认的构造函数，以便您仍可以在设计器中使用它们.

编辑=========

为什么我的答案被选为1?完全没有任何意义.

Make sure you give each one a default constructor so you can still work with them in the designer.

EDIT =========

Why was my answer voted a 1? That makes no sense at all.

首先创建一个名称为Parent的表单，标识符应为Public:

First Create a form name it Parent, identifier should be Public:

public partial class Parent : Form
{
 // You can have Protected variables and Methods
}

现在您可以将子表单名称命名为child

Now you can make child form name child

public partial class child : Parent
{
 // you can use all protected variables and methods of Parent class
}

此处 [ ^ ]是Microsoft所谓的视觉继承的演练.

看看是否有帮助.
