创建form1的新实例并更改该表单属性 [英] Creating a new instance of form1 and change that forms property

问题描述

在我当前的项目中，我制作了一个粘滞便笺式应用程序，其中用户可以打开多个相同表单的实例。然而，我想知道在C＃中是否有一种方法可以创建form1的新实例，但是新窗体的标题/文本/标题为form2。

如果这是可以实现的，我想推动如何编写我的应用程序的部分的正确方向。

谢谢大家。

我意识到我忘了添加一些重要的东西：

我需要能够计算当前打开多少个实例。从那里开始，我将为表单文本添加+1。

解决方案

尝试从类中访问表单属性：

  MyForm newForm = new MyForm（）; 
 newForm.Show（）; 
 newForm.Text =Form2; 
  

或者从当前表单调用一个方法来设置文本：

  //在MyForm中
 public void SetTitle（string text）
 {
 this.Text = text; 
} 
 
 //调用方法
 MyForm newForm = new MyForm（）; 
 newForm.Show（）; 
 newForm.SetTitle（Form2）; 
  

希望这有助于您！

打开的表单数量可以尝试如下所示：

  //在MyForm中
 private int counter = 1; 
 public void Counter（int count）
 {
 counter = count; 
} 
 //示例
 MyForm newForm = new MyForm（）; 
 counter ++; 
 newForm.Counter（counter）; 
  

这可能会让人困惑，但可以说你有一个按钮可以打开一个新的实例同样的形式。由于您有一个窗体在开始时打开 counter = 1 。每次点击该按钮时，它都会向窗体发送 counter ++ 或 2 。如果你打开另一个表单，它会发送 counter = 3 等等。可能有更好的方法来做到这一点，但我不确定。

In my current project, I am making a sticky-note type application in which the user can have multiple instances open of the same form. However, I was wondering if there was a way in C# where I can create a new instance of form1 however have the new form's title/text/heading to be form2.

If this is achievable, I would like a nudge into the correct direction of how to code that part of my app.

Thanks everyone.

--EDIT--

I realized I forgot to add something important:

I need to be able to calculate how many instances are currently open. From there I will add +1 to the form text.

解决方案

Try accessing the forms properties from the class:

MyForm newForm = new MyForm();
newForm.Show();
newForm.Text = "Form2";

Or call a method from the current form to set the text:

// In MyForm
public void SetTitle(string text)
{
    this.Text = text;
}

// Call the Method
MyForm newForm = new MyForm();
newForm.Show();
newForm.SetTitle("Form2");

Hope this helps!

To check the amount of forms open you could try something like this:

// In MyForm
private int counter = 1;
public void Counter(int count)
{
    counter = count;
}
// Example
MyForm newForm = new MyForm();
counter++;
newForm.Counter(counter);

It may be confusing to use, but lets say you have a button that opens a new instance of the same form. Since you have one form open at the start counter = 1. Every time you click on the button, it will send counter++ or 2 to the form. If you open another form, it will send counter = 3 and so on. There might be a better way to do this but I am not sure.
